You will get a scalable FastAPI backend with auth, database, and Docker deployment
Rising Talent
Project details
Most freelancers hand you working code — I hand you a production-ready system you can actually ship.
I'm a senior Python engineer with 6+ years building high-performance backends for startups and enterprise products. I specialize in FastAPI — one of the fastest Python frameworks available — and I architect every API to be async-first, well-documented, and easy for your team to extend.
What makes this project different:
→ Clean, modular code with full OpenAPI/Swagger docs included
→ JWT auth, role-based access, and secure environment configuration
→ Docker + Docker Compose setup so it runs identically on every machine
→ Ready to deploy on AWS, GCP, or any cloud platform
→ Celery + Redis for background tasks if your app needs them
Whether you're building an MVP or scaling an existing product, I'll deliver a backend that's solid, fast, and built to grow with you.

Job Success
Namangan, Uzbekistan - 11:41 pm local time
Most of my work is one of three things:
Voice agents that hold a conversation. I spent 16 months building a voice-interactive companion app for dementia care — AI-generated personas, full STT/TTS pipeline, and conversational memory drawn from each patient's background, likes and life events. Latency and turn-taking are what make a voice agent feel human or feel broken, and that is the part I engineer rather than configure.
Private and on-prem LLM deployment. I have put a self-hosted LLM stack onto a client's own Ubuntu server with an NVIDIA GPU — resolving CUDA and dependency conflicts, then handing over installation and implementation documentation so their team could run it without me. If your data cannot leave your network for legal or policy reasons, this is the work.
LLM pipelines and evaluation at volume. I built a system that scored 7,000 academic essays in a single week — ingesting PDF and DOC files from cloud storage, running GPT-4 against a rubric-derived prompt tuned to the client's tone of voice, batch-processing with logging and error handling, spot-check QA, and emitting per-essay scores, written feedback and rankings. Delivered a month ahead of deadline.

Core stack: Python, FastAPI, PyTorch, CUDA, OpenAI API, RAG and vector databases, Django, PostgreSQL, Docker.
I hold a 100% Job Success Score, I reply within a few hours, and I will tell you early and plainly when something in a spec won't work — before it costs you a sprint.
