We are looking for an experienced brand naming / branding professional to help us rebrand our technology startup. ABOUT THE COMPANY We are building a hyperlocal marketplace that connects people who need help with everyday tasks with nearby people willing to complete those tasks and earn money. Examples include moving a few boxes, picking something up, yard work, tech help, tutoring, simple home support, and other everyday needs. The requester posts the task, describes what they need, chooses the time/location, and sets the price. Nearby users can view the opportunity and either accept the price or submit a counter-offer. The core idea is simple: people nearby helping each other — neighbors helping neighbors — while giving people a flexible way to earn money using th...

...Prediction Bot” into a fully working Android app. The concept is simple: feed the app either live video or pre-recorded movement data of chickens near a roadway and have it predict if, when, and where a bird will step onto the road. The platform is strictly mobile and Android is the only operating system I need supported. Here’s what I expect: • A lightweight Android application (Kotlin or Java) with a clean UI that shows a camera preview or data feed and overlays the real-time prediction. • An on-device model—TensorFlow Lite, PyTorch Mobile, or a comparable framework—that can run offline and outputs a confidence score plus an ETA for the crossing. • A simple stats panel logging every prediction with time-stamp so I can review accur...

We need an experienced Android Java developer to review the existing application, understand the current Azure Face API integration, and modify the application so it can work reliably with our new Python facial-recognition API. The work will be completed in two phases. ## Phase 1 – Replace Az...

I’m looking for a patient, engaging tutor who can guide true beginners through the fundamentals of Japanese grammar and vocabulary. The goal is to build a solid base so that, over time, everyday conversation and simple reading feel natural. Here’s what I have in mind: • Weekly live sessions (audio or video) that break down new grammar points in clear, practical examples. • Targeted vocabulary drills that move beyond word lists into real-life usage. • Short homework or quizzes after each lesson so I can track progress between meetings. Your teaching style should be interactive—screen-sharing example sentences, using spaced-repetition flashcards, or any other tools you prefer (Anki, Google Docs, digital whiteboards, etc.). Native speakers are pref...

...free to integrate Firebase Cloud Messaging if it speeds things up; I just need the service to scale and to handle basic fail-over scenarios.

I’m looking for a developer who can build a lean, production-ready Android shopping app that does one thing exceptionally well: move users from “Add to Cart” straight through a secure checkout and payment gateway. Scope • Native Android build (Java or Kotlin) that runs smoothly on the current OS versions. • Core screens: simple product view (fed by my existing API), cart summary, shipping details, payment screen, and order confirmation. • Integrated payment gateway—Stripe is preferred, but I’m open to your recommendation as long as it supports major cards and works worldwide. • Guest checkout only; no user sign-up or login flows. • Clear error handling, validation, and success/fail callbacks so I can track each order&...

I’m building a web application and need a seasoned Java full-stack developer to work alongside me from backend through to the React UI. The help I’m after is truly end-to-end: designing or extending Java REST APIs, wiring them into responsive React components, and keeping everything clean, tested, and well-documented. You’ll jump between backend logic (Java 17, Spring Boot, JPA/Hibernate, Maven) and the React frontend depending on the task at hand, always with an eye on performance, security, and code quality. Unit and integration tests, pull-request reviews, and occasional CI/CD tweaks in GitHub Actions and Docker are part of the routine. Acceptance criteria for anything we merge are straightforward: • All automated tests pass and new code mee...

...accept or decline, and both parties get confirmation inside the app. Although real-time tracking and payment integration are off the critical path for this first version, the codebase should be clean and modular so those features can be bolted on later—or even ported to iOS or Web without a full rewrite. Deliverables • Production-ready Android app (APK + Play Store-ready bundle) • Full Kotlin/Java source code in a Git repo with README setup instructions • Simple backend (Firebase, Supabase, or similar) handling user auth, ride data, and push notifications • Brief technical document outlining architecture, key libraries, and where future modules (tracking, payments) will plug in • One walk-through session to hand over the project and answer...

I have a fully-built mobile app in FlutterFlow that I’m now ready to take native. Your job is to reproduce the entire experience in Swift for iOS and Java for Android, matching the original design pixel-for-pixel, duplicating every feature, and retaining the same smooth performance—or improving it where possible. The current build works, but being tied to FlutterFlow limits my control over custom code and optimisation. I’ll provide the existing FlutterFlow project, Figma screens, backend endpoints, and a brief test plan so you can see what “identical” really means. Key expectations • UI/Design fidelity: layouts, colours, typography, animations, and any custom widgets must look and feel exactly the same on both native platforms. • Feature...

I’m ready to scale a high-ticket tutoring program and need a marketer who can tie together AI-driven insights, GoHighLevel automations, and sharp creative across both social media and email. Here’s what success looks like for me: our message consistently reaches parents and adult learners on Facebook, Instagram, LinkedIn, and YouTube, while a well-structured series of automated email sequences inside GHL nurtures every lead until they book a consultation. I already have the core offer and brand voice; what I lack is the technical orchestration and ongoing optimisation that turns traffic into qualified appointments. You’ll be expected to: • Build or refine funnels inside GoHighLevel, including tags, pipelines, triggers, and dashboards. • Craft AI-a...

I’m committing the next eight weeks to sharpening my SQL and Excel skills and I’d like you to steer the process. I already work comfortably at an intermediate level, but I’m still spending far too long turning raw data into clear, compelling visuals. My goal is to leave this programme able to move from question to insight quickly—writing tidy, well-structured SQL queries and translating the results into polished dashboards and charts inside Excel (and, where it makes sense, Power BI). Here’s how I picture our collaboration: • A structured learning path that steadily raises the bar each week, mixing short theory explanations with hands-on exercises drawn from real business scenarios. • Screen-sharing or paired-coding sessions where you watch me wo...

...logged, real-time push notifications must alert relevant team members so nothing slips through the cracks. Because this will be used exclusively by trained security staff, the interface has to be fast, uncluttered, and usable with one hand—think large buttons, offline caching in spotty coverage areas, and a minimal number of taps to completion. Deliverables • Android Studio project (Kotlin or Java) with clean, well-commented code • Signed APK ready for internal testing and deployment • Implementation of: – Incident reporting form – Photo & video upload – Real-time notifications (Firebase Cloud Messaging or similar) • Brief set-up guide covering build steps and configuration of the notification service Th...

...clutter-free; think a single address/search bar, slim toolbar, and nothing that distracts from the page content. Although the interface must stay minimalist, I still want users to be able to tweak it—simple theme or accent-color switches, the ability to move or hide the toolbar, and a setting to choose the default search engine will be enough. Please build on standard Android WebView (Kotlin or Java in Android Studio) and keep the codebase well-commented. I will need: • Release-ready APK • Full source code with build instructions • A short README outlining how the incognito implementation works and which UI elements are customizable I’ll test by installing the APK on Android 10-14 devices and checking that no browsing data persists betwee...

...PM. The work centres on a large-scale web application already in production. Your day-to-day focus will be split between building new modules that the business team has specced out and keeping the current codebase healthy—refactoring, fixing bugs and making incremental performance gains. We run a lean stack, so deep knowledge of core PHP and core Java is more valuable to us than framework expertise; if you can read, write and optimise plain PHP/Java, you’ll fit right in. A typical week will involve: • Scoping and coding new features from user stories supplied by the product owner • Reviewing legacy code, identifying hot spots and patching them before they escalate • Committing well-documented code to our Git repo and walking the QA engine...

I need a straightforward Android application that lets users access the app through a secure username-and-password login screen. At this stage I am focusing only on Android, so you can use Android Studio with Java or Kotlin—whichever you are most comfortable with. Core scope • Clean, intuitive login interface • Secure credential handling (local encryption or a backend such as Firebase/Auth0—open to your best-practice suggestion) • Well-structured project files and clear comments so I can maintain the code later Optional next steps (not in this job but good to keep in mind) could include subscription flows or cloud integration, so please architect the code with scalability in mind. When you hand over the APK and full source code, I will test the...

...trades from both demo and live accounts Push notifications are not required, so everything should happen in-app. Please follow cTrader’s recommended OAuth security practices, store tokens safely, and make sure the same codebase can be switched between demo and live environments with a simple build flag or configuration file. Deliverables must include: • a clean Android Studio project (Kotlin or Java) that compiles without external tweaks • documented source code covering authentication, REST calls, and WebSocket streaming where needed for trade execution feedback • a short README explaining how to register the app in cTrader, set client ID/redirect URI, and switch between environments • an installable APK for quick testing I’ll consider th...

Computer Science Tutoring for Sep 2026. Total of 6 sessions (2 sessions per week).

I run an ongoing web application project built on Java 17, Spring Boot, and the latest Angular stack. The codebase is healthy, the backlog is full, and I need an extra set of expert hands during standard USA working hours. If you already have a daytime role but can reliably commit to a second engagement, this collaboration should fit you perfectly. You will pair with me to extend existing micro-services, refine Angular components, create REST endpoints, and tighten unit and integration test coverage. Clean, well-documented code and frequent Git commits are a must; I review in real time while we overlap online, so clear communication matters as much as technical skill. Deliverables each week • Merge-ready pull requests that compile on Java 17 and pass the CI pipeline ...

Remote File Manager • From the management panel, we should be able to access the connected Windows system’s file structure. • Upload files to the system. • Download files from...

My Maven-managed Java 8/11 web app refuses to start in Tomcat 9. The code compiles cleanly, dependencies resolve, yet as soon as I hit catalina run the server aborts during start-up. I need a fresh pair of eyes to identify and fix whatever configuration detail is blocking the boot sequence. What you’ll be diving into: • Multi-module Maven project (Java 8 baseline, also builds under 11) • Standard war packaging, no Spring Boot embedded server • Tomcat 9 installed outside the project, launched via startup scripts on macOS and a staging Linux box Scope of work 1. Analyse startup logs and pinpoint the failing component or mis-configured resource (, , , or Maven plugin settings). 2. Apply the fix or guide me to adjust the configuration so the appli...

...Design direction The interface must stay simple and minimalistic—clean typography, plenty of white space, and intuitive navigation similar to native Material-You guidelines. What I will provide • Any necessary brand assets and endpoint documentation for server-side validation. • Prompt feedback on UI drafts and test builds. What I expect back • Complete Android Studio project (Kotlin or Java) with well-commented code. • Working APK for hands-on testing. • Brief setup/read-me explaining dependencies, build steps, and how to point to staging vs. production payment keys. Once the build passes functional tests and the code review, I’ll release final sign-off. Looking forward to a straightforward, well-structured implementation that ...

...structured data (CSV, Excel, or a simple database), explore it quickly through filtering and pivot-style summaries, run common statistical or machine-learning routines, and then export clean visual or tabular reports. You’re free to choose the tech stack you feel delivers the best user experience—Python (PyQt, Tkinter, or Electron with a Python backend) or a modern compiled language such as C#/.NET or Java are all acceptable. What matters is that the interface remains intuitive for non-technical staff, computations are performant on mid-range hardware, and the codebase is well documented for future maintenance. Core deliverables • An installable application (Windows first; macOS/Linux portability is a plus) • Source code in a public or private repository...

I’m ready to move from concept to a fully functioning Android application and need a developer who can guide the project from architecture through store release. The focus is 100% on the Android platform, so deep knowledge of Android Studio, Kotlin/Java, Material Design guidelines, and the Google Play submission process is essential. I’ll provide the core idea, wireframes, and any graphic assets I already have. You’ll translate those into clean, maintainable code, implement the features we agree on, test across common device sizes/OS versions, and hand over everything—source code, build files, and brief setup notes—so I can compile the project independently in the future. If you’re comfortable integrating APIs, handling offline data, and creatin...

...Wire up banner, video and interstitial ads so they display and track correctly. • Complete the remaining API endpoints that link the website to the central database, then write clear, developer-friendly documentation for them. • Refactor the existing Java and PHP code so the new API calls, wallet functions, recharge/payment gateway, subscription package management, CRM member tools, and illegal short-link controls run smoothly from the same backend interface. To succeed you’ll need solid PostgreSQL and MySQL skills plus fluency in both Java and PHP. I already have short-link creation, access tracking, data export and a basic member dashboard in place; your work will elevate these pieces and make daily site-to-database tasks seamless. Please outline ...

I need a single software tool built for Windows that brings together modules written in C#, Java, JavaScript (with Node.js), and Python. Each language already plays a specific role in my current workflow, but everything now lives in separate scripts. The goal of this project is to consolidate that functionality under one cohesive interface so the user experience feels like a unified application, even though different runtimes sit behind the scenes. Here is what I have in mind: • C# and Java components handle performance-critical routines and existing libraries I can’t easily replace. • Node.js and browser-side JavaScript power a lightweight GUI/dashboard. • Python remains in charge of data preparation and quick scripting tasks. Your job is to a...
