I have a React-Native application that runs on both iOS and Android and most of the core functionality is already in place. The pieces that live in my claude code compile, but several behaviours are not working as expected once the mobile client calls them. Help me develop my tinder app What I need from you • Step through the existing claude code and the corresponding React-Native components, locate the breaking points, and implement clean fixes. • Explain any changes you make so I can keep the codebase maintainable. Short Loom videos or concise comments in pull requests are perfect. • Test on both iOS and Android builds to confirm that the patched code behaves identically across platforms. Tech you will touch React-Native (latest stable), claude code functions (Ja...
Experienced TradeStation/EasyLanguage developer, (minimum 5 years' experience), expert in FSM logic sequencing, aligning the two stateless states (omc-stl and omo-stl), then prioritize entry/exit events/conditions to preclude false entries and exits (FEE)... understanding its existing architecture and state/transition behavior, diagnosing excessive losing-trade sequences, and making controlled modifications within the existing Trade Station/EasyLanguage environment. All in a TQR compliant system.
I have a production-ready Flutter codebase that is misbehaving on Android. The problems show up every time I run the app—no randomness involved—so you’ll be able to reproduce them quickly. What I’m seeing: • UI/UX issues: the user screen doesn't display • Performance problems: janky scrolls and noticeable frame drops on list-heavy pages. • Functionality errors: many API-driven features fail to return data even though the backend is healthy. Your task is to dive into the existing Dart code, locate the root causes and deliver clean, well-commented fixes. Once done, I expect a debug build for review, followed by a signed release APK/AAB. All changes should compile without warnings, run smoothly on Android 8+ devices, and keep the current archi...
I need an Android-only application that mirrors the core functionality of MobileRecorder24 while adding a fully integrated key-logging module. The build must capture the screen and system audio in the background and log every keystroke, saving all three data streams locally with the option to auto-upload to a URL I will supply later. Because I want the app to stay light, the interface should be simple and minimalistic—just a clean dashboard that lets me start or stop recording, browse stored files, configure upload credentials, and view basic status indicators. No extra visual clutter, no unnecessary animations. Your work should result in: • A signed, install-ready APK that runs smoothly from Android 8 onward • Well-commented source code (Java or Kotlin) so I can ...

C++ Systems Engineer - High-Performance Data Processing | $3000 Fixed I'm looking for an experienced C++ engineer to work on a systems-level project involving high-performance data processing and an existing C++ codebase. Budget: $3000 fixed price Language: C++17/20+ Environment: Linux / Git ## Project The project involves extending and improving an existing C++ application according to a detailed technical specification. The work will involve understanding the existing architecture, implementing new functionality, and ensuring that the changes integrate cleanly with the current codebase. The project is intended for an engineer who is comfortable working below the application level and cares about performance, correctness, maintainability, and clean design. ## Requirements Str...
I’m looking for help tracking down and fixing stubborn syntax errors in my Python project. Everything is being written and run inside Visual Studio Code, so you’ll need to be comfortable using its integrated debugger, linting extensions, and typical Python tool-chain (virtual environments, pylint/flake8, etc.). Scope of work: • Open the current repository in VS Code and reproduce the syntax errors I’m seeing. • Explain the root causes and resolve each error without altering the intended logic. • Add comments where fixes were applied so I can follow the changes easily. • Run the updated code to confirm it executes cleanly in VS Code’s terminal. • Suggest any small configuration tweaks (, recommended extensions) that would prevent sim...
I’m putting together a “flash-style” application that lets adult learners explore core cryptocurrency concepts in a classroom setting. The aim is to keep everything simple enough for first-time students yet authentic enough that they see real-world mechanics in action. Here’s what I need the build to cover: • Data encryption built in from the ground up so students can encrypt and decrypt sample strings and immediately view the results. • Basic blockchain integration that spins up a local test chain, writes a few dummy transactions, and then visualises block creation. • A small, self-contained wallet module that can generate keys, sign test transactions, and show balances—all within the local sandbox, no live coins involved. The tool only ...
I need a fresh set of eyes on a Windows app that talks to a PS4 over the local network. You will run the build on your own test console, load GoldHEN with ps4debug, and confirm that everything handshakes exactly the way the documentation describes. Your background can be beginner-level with general PS4 homebrew, but I do expect you to have spent plenty of time using GoldHEN itself; the nuances of its debugging menus and payload handling are what matter most here. As long as your PS4 is already jail-broken, on the same LAN as your Windows PC, and ready for payloads, you’re good to go. What I’ll hand over: • the Windows executable, full source, and a quick-start guide • contact details so you can reach me live while you test What I need back: • captured logs (...
Our eKYC platform is live, but the two-factor authentication built into the public weblink is failing consistently. Users receive the OTP/SMS push, enter the code, and the process stalls with a generic “authentication error” before redirecting them back to the login page. Server logs show no obvious stack trace, so I need someone to dig in, reproduce the fault, and patch it without disrupting the rest of the flow. What I know so far • Front-end: React single-page component that posts to a Node/Express API • Auth layer: JWT for the first factor, OTP via Twilio for the second • Database: PostgreSQL 14 • Error appears only in production, not in our staging environment Your job 1. Trace the call from the React form through the Express middleware to p...
I need a compact firmware-and-hardware solution that lets a PIC microcontroller, programmed with the XC8 compiler, manage a battery-powered power supply built around a lead-acid pack. Here is what I am after: the PIC should start up from the battery, regulate or switch the output rails as required, continuously read the pack voltage, temperature or any other basic health indicators, and trigger clear actions (for example, low-voltage cutoff or status signalling) before the battery reaches critical limits. A simple serial, I²C or even LED indicator scheme is fine for status feedback—as long as I can read the key parameters easily during bench tests. Please base the code on MPLAB X + XC8 so I can compile and tweak it locally. If you prefer a specific mid-range PIC that is re...
Customize Your Existing AI/Web Pipeline for Autonomous Vendure Debugging Hello, We are looking for an engineer with Vendure or a closely related Node.js/TypeScript e-commerce background to adapt the AI programming, website-debugging, testing, or automation pipeline you already use into a fully automated debugging, testing, and delivery-verification pipeline for a Vendure storefront. You do not need to invent a new framework from scratch: if you have a pipeline you already use for your own projects, you may fine-tune it, assemble it with other components, or replace our suggested components. We already have a working pipeline prototype and a basic engineering foundation. The current design uses CAO as the coordination and supervision layer, OpenHands or CrewAI as bounded code-execution a...
We have a working n8n workflow that generates 24-second vertical marketing videos using , Google Gemini agents, ElevenLabs, and Cloudinary. A full technical audit has already been completed — the problems are identified and documented. We need an experienced n8n specialist with hands-on knowledge of AI video generation APIs to implement the fixes. The audit identified the following issues: Bridge frame captured at wrong timestamp causing repeated frames at splice points between segments Sanitisation function corrupting the negative prompt constraints No character anchor — character identity only carried as free text, causing drift between segments Image-to-video model treating reference frame as starting frame instead of identity reference 3 independent audio tracks p...

This isn't a spec-driven, cog-in-a-machine role. You will be stepping in to audit an existing ASP.NET Core codebase, stabilize the production environment, and lead the architecture for new enterprise features. If you enjoy the detective work of untangling unfamiliar code and the satisfaction of building scalable Azure infrastructure from scratch, this is for you. What You'll Do Codebase Rescue & Audit: Dive into an existing ASP.NET Core application to identify security gaps, structural flaws, and architectu...
Send me sample of your best work. I am looking for a highly experienced software developer to complete, improve, test, and commercially launch an existing proprietary business software application. To protect the project, the public posting will not disclose the software's industry, proprietary business logic, unique features, calculations, workflows, or competitive strategy. Full details will be shared only with bidders I am seriously considering. I would like my project done in 8 to 10 days. The code must be 100% original. You must speak, read, and write English proficiently. The developer must be an expert in AI-assisted and AI-generated code and must be capable of auditing existing code rather than assuming generated code is correct. You must identify and fix incomplete, broken, ...
You will step into a senior development seat inside a Pune office, taking ownership of ABAP RESTful Application Programming Model (RAP) work across a live S/4HANA landscape. Day to day, I’ll rely on your 3-4 years of ABAP RAP Project experience to craft CDS views, expose robust OData services, and push modern ABAP syntax to its limits. Because you have already built Fiori applications, you’ll also advise our functional team on UI possibilities while ensuring smooth back-end integration. Solid grounding in ABAP Objects, sharp debugging instincts, and hands-on API development are essential; they keep our release cycles tight and our interfaces clean. This is a pure work-from-office role in Pune, so your physical presence and collaboration with both functional and technical ...
I’m running an iPhone 13 on iOS 16.5.1 with the rootless Dopamine jailbreak and I need a custom tweak that makes Safari believe it is receiving a live camera feed while, in reality, it is streaming a pre-recorded video. Existing “virtual camera” solutions fail with Safari/WebRTC, so this must be built specifically for that environment. Primary goal • Whenever a website opened in Safari asks for camera permission, it should receive a continuous MP4 video I have stored on-device—not the physical rear or front camera feed. There is no need for overlays or live-feed switching; the real camera should be completely bypassed. Configuration • I’d like to point the tweak to the video of my selection in the camera roll or via a static file path (e.g., th...
I am a junior design-verification engineer working on projects that rely heavily on UVM and SystemVerilog. The scope of my day-to-day work shifts—from setting up testbenches and drafting verification plans to digging through waveforms when bugs appear—so I’m looking for an experienced engineer who can step in whenever a challenge arises. Here’s what I need from you: • On-demand problem-solving whenever I hit a roadblock, whether the issue is in stimulus generation, coverage closure, or a stubborn simulation mismatch. • Broader guidance and mentorship that helps me grow: reviewing my overall approach, suggesting best practices, and explaining why a particular methodology choice matters. Code reviews are welcome when time permits, but the primary focu...
Tools and technolgy of IA Agent N8N Evolution API Supabase OpenAI My internal IA Agent suddenly stopped responding even though nothing in the environment was changed. I have already gone through the configuration files and settings, and everything appears normal, yet the service still stays silent. Here is what I can tell you: • Symptom: the agent accepts a request but never returns a reply—no errors, no logs beyond the initial handshake. • Onset: the problem surfaced randomly; there were no updates, deployments, or hardware changes that I’m aware of. • Attempted fix: only a configuration review so far. I have not restarted the whole system or re-installed the package, so you’re free to take those routes if they make sense after your analysis. ...
We have an existing astrology platform/mobile app that is already developed and running. We are looking for an experienced developer to fix a number of small existing issues and correctly configure/verify our advertising conversion events. This is **not a complete app development project**. Most of the development is already done. We mainly need bug fixing, event tracking correction, testing, and optimization. Main Tasks 1. Fix Small App Issues There are several small/silly issues in the existing app that need to be checked and fixed. Examples may include: * Small UI/UX issues * Buttons or actions not working correctly * Minor API/backend issues * Incorrect redirects * Small login/session issues * Minor notification issues * Fixing unexpected app behaviour * Other small bugs found du...
My OpenCart shop’s core has started flooding the error log with three recurring problems: • deprecated functions • outdated PHP-version warnings • deprecated class usage Because the errors sit inside core functionality, they risk slowing the site and exposing security gaps. I need a developer who knows OpenCart inside out to clean up the codebase, silence the warnings the right way (no error-suppression hacks), and leave every storefront feature working exactly as before. What I expect once you are done is simple: noticeably faster page loads and the peace of mind that the store is running on a tighter, more secure foundation. Typical tasks will include tracing the log entries back to the offending files, refactoring or replacing the legacy calls, testing...
I have a working Rust codebase that spins up a datacenter-grade proxy in front of a target site. Functionality is solid, but raw throughput is lagging behind expectations. The immediate goal is performance optimization with a laser focus on execution speed—latency per request must drop and overall RPS needs to climb noticeably without sacrificing stability. You’ll be diving into a fairly idiomatic async stack (Tokio + hyper) that already handles connection pooling, routing, and basic health checks. The challenge is to profile, pinpoint, and remove bottlenecks in the critical path: connection handshake, frame parsing, and response streaming. If you prefer flamegraph, cargo-bench, criterion, or any other standard Rust profiling tool, feel free to bring it in; I care about measur...
