FastAPI Jobs

I want to prove that a phone call can flow seamlessly into Bitrix24 without human intervention. The minimal-viable bot should answer an incoming call, ask two-to-three preset questions, understand the caller’s short-sentence replies (it needn’t cope with one-word grunts or long story-telling yet), pull out the key data, and write the result into my Bitrix24 via its REST API. Here’s the journey I need running end-to-end: 1. Public phone number receives the call and hands it to the bot. 2. Bot plays a text-to-speech greeting and questions. 3. Caller responds; speech-to-text converts the audio. 4. An NLP layer extracts structured fields such as “desired service”, “company name”, and “contact channel”. 5. The JSON payload is push...

I’m expanding our product team and need a backend specialist who can dive straight into our Python codebase, extend our microservices, and keep our PostgreSQL layer healthy and performant. The role is fully remote, part-time, and highly collaborative; daily stand-ups, pair sessions, and code reviews are the norm, so you must be comfortable communicating fluently in Portuguese or Spanish. Our current stack centres on Python 3.x, FastAPI, Celery, Docker and Kubernetes, all wired up to PostgreSQL. Your day-to-day work will involve designing and refining REST / gRPC endpoints, improving test coverage, optimising SQL queries, and ensuring smooth CI/CD releases. Every two-week sprint you’ll own a set of stories, ship merge-ready PRs, document your changes, and jump into peer reviews...

I need production-ready software that proves out the latest frontier-model capabilities from end to end. The work spans everything from designing the data layer to wiring up sleek UIs, then packaging and deploying so that real users can click around and see the model in action. You can reach for the stack that lets you move fastest—Python/Django or FastAPI, Java/Spring Boot, TypeScript/Node.js or , even Rust, C#, or modern C++. Cloud services (AWS, Azure, GCP) and containerisation with Docker/Kubernetes are welcome if they speed delivery; I’m flexible as long as the final result is easy to stand up and maintain. Frontier-model features sit at the heart of each build. Whether it’s natural-language understanding, computer-vision pipelines, data-driven recommendations, or ...

I run a market-research agency and I need a developer who can turn raw survey results into an easy-to-navigate, web-based dashboard and also set up a clean redirect flow for respondents once they finish a study. Here’s what I’m after: the dashboard should present the data primarily as sortable, paginated tables or lists. I want anyone on my team to be able to slice the data on the fly with interactive filters—think demographics, wave, device type—without waiting for a page refresh. Charts and maps aren’t essential right now; clarity in table form is. The source data will arrive in CSV or via API from our survey platform, so you’ll need to build (or hook into) an automated pipeline that fetches the latest file, stores it securely—MySQL, Postgr...

I’m building a modern, responsive AI-powered web tool that relies on React for the UI and a Python/FastAPI backend connected to Supabase/PostgreSQL. Core functionality centers on three AI capabilities—natural language processing, image recognition, and predictive analytics—exposed through well-structured APIs. The scope includes: • Frontend: component-driven React interface with TypeScript, state management, and full mobile responsiveness. • Backend: FastAPI services, authentication (JWT or Supabase Auth), role-based access, and real-time endpoints. • Database: relational modelling in PostgreSQL, Supabase edge functions, and row-level security. • AI integration: orchestrating LLM or vision endpoints (OpenAI, Anthropic, or custom models) and ...

I’m building the first-round MVP of an Australian telephone polling platform and need a developer who can take it from concept to a working cloud-hosted product. The core workflow is straightforward: the system automatically dials a list of phone numbers, asks scripted questions, recognises spoken answers with NLP-based voice recognition, and stores each response for later analysis. It must comfortably interpret multiple-choice replies (e.g. “Press or say one for…”), open-ended comments, and numeric inputs such as postcode or age. Key capabilities I need implemented: • Automated outbound call scheduling with retry logic and time-zone awareness. • Real-time voice recognition powered by Natural Language Processing so the caller can respond naturally rath...

I’m putting together a full-stack e-commerce application, PhoneHub, and I need an experienced developer who can take it from architecture to deployment. The storefront will run on React + Vite with Tailwind CSS for styling, while the API layer will rely on Python, FastAPI, and SQLModel. Key piece of the build is an AI shopping assistant whose main job is to generate recommendations. It must surface related accessories, current best-sellers, and truly personalized suggestions drawn from each visitor’s behaviour. I plan to power this with ChromaDB and a RAG-style retrieval flow, so familiarity with vector databases and prompt engineering is a plus. Core platform requirements • JWT authentication and role-based access • Product catalogue with bulk upload support ...
