3. AI Model Inference API Gateway Category: Backend Development / API Engineering Budget: £1,350 GBP — Fixed Price, 3 Milestones Project deadline: Saturday, 10 October 2026 Description: We're building a backend gateway that sits in front of one or more machine learning models and exposes them as a clean, versioned inference API. The gateway needs to handle request queuing under load, model version routing, response caching where appropriate, and consistent error handling when a model fails to return a result. This is a pure backend/API service — no UI work involved. Key requirements: • Strong backend/API development skills (Python, Java, or C#) • Experience serving ML models via API (e.g. FastAPI, TorchServe, Tri...
I’m ready to turn my existing REST API into a polished React Native mobile application. The API is fully documented and the screen designs are complete; what I need now is a clean, TypeScript-based codebase that follows good component architecture and stays as close to pure React Native as possible. Core requirements • Authentication: wire the app to my API using Basic authentication and persist credentials securely. • Navigation & UI: a tabbed interface that presents a master list (pulled from the API) and corresponding detail views, matching the provided Figma files pixel-for-pixel. • Offline experience: cache the entire app’s data locally so users can browse previously fetched content without a connection, with automatic ...
...Milestones Project deadline: Tuesday, 6 October 2026 Description: We need a backend engineer to build a real-time event streaming service that ingests high-volume events from multiple producers, queues them reliably, and routes them to downstream consumers with guaranteed delivery ordering. The service needs to handle backpressure gracefully, support consumer groups, and expose a clean internal API for publishing and subscribing to topics. This is purely a backend/messaging-infrastructure build — no UI involved. Key requirements: • Strong experience with Kafka, RabbitMQ, or a comparable message broker • Solid understanding of event-driven architecture and idempotent consumers • Experience designing internal pub/sub or queueing APIs • Comfortable workin...
I work with MRMS radar data stored as .grib2 files on Amazon Web Services and need a reliable way to turn those files into standard GEMPAK (.gem) datasets for further data-analysis workflows. The exact path you choose is up to you—whether you craft a Python or Bash script, chain existing utilities such as wgrib2, leverage native GEMPAK converters, or wrap everything inside a small API or container. What matters is that the solution consistently ingests the MRMS archives from AWS, performs the format translation, and leaves me with clean, ready-to-use .gem files. Key points I have in mind • The conversion must run unattended once configured, ideally accepting a date/time or file list and processing in batch. • Output .gem files should preserve the full MRMS met...
...fits comfortably within WhatsApp’s character limits and looks clean on both Android and iOS. • Format the order menu so customers can see numbered or bulleted options and understand the next step at a glance. • Activate the auto-reply inside my WhatsApp Business settings—or provide a simple, screenshot-driven walkthrough I can follow myself. If you prefer to work through the WhatsApp Business API, that’s fine as long as the end result still triggers for all incoming messages. Once we start, I will send over the exact list of menu items, product codes, and my preferred sign-off. Your final deliverables are: 1. The ready-to-paste message text. 2. A brief setup guide (PDF, doc, or annotated screenshots). Let’s keep the wording friendly...

...REST-style API exposed on my Hostinger account that reads from that database and returns clean, focused search results. If someone asks the endpoint for “fridge”, I must not see fridge magnets or unrelated accessories—just actual refrigerators. The API has to run behind a localhost restriction (i.e. accept calls only from ), yet still sit on Hostinger so I can interact with it through server-side scripts. Key points you should cover while building: • Schedule the scraper to run monthly without manual intervention. • Respect Amazon’s structure changes with selectors that are easy for me to tweak later. • Store data in a well-indexed MySQL schema so the API responds quickly. • Deploy the code on Hostinger and docume...

We need someone who understands the complete realtime voice pipeline and can benchmark, optimize and redesign the architecture where necessary. Technologies Already Tested We have already experimented with: OpenAI Realtime OpenAI voice models Sarvam AI STT/TTS ElevenLabs TTS Plivo Twilio SIP/telephony Streaming STT → LLM → TTS architectures Realtime speech-to-speech architecture Our current implementations work, but the cascade architecture introduces noticeable latency, while our current realtime implementation is more expensive than our target. We therefore need an expert to find the optimal architecture rather than simply replacing one API with another. Primary Goals 1. Re...
...Bank of Jamaica’s regulatory Sandbox. Before I take that step, I need a fresh set of expert eyes to validate two things: 1. The overall security posture of each application. 2. Their alignment with Jamaican and international regulations covering Data Protection & Privacy, Anti-Money Laundering (AML), and Electronic Payments & Transactions. You will receive architecture diagrams, user flows, API documentation and direct access to a staging environment for both apps. I am specifically interested in whether my encryption strategy, authentication logic and general vulnerability surface meet current industry best practices (OWASP Top 10, ISO 27001, PCI DSS, etc.). On the compliance side, I want a clear gap analysis that maps each requirement in the above-mentioned re...
