I build and improve Python backends for SaaS products: REST APIs, database integrations, and AI features using Django, FastAPI, PostgreSQL, and RAG. I'm a Top Rated developer with a 100% Job Success Score and 7+ years of software development experience. My Upwork work history includes a 445-hour Django engagement, alongside projects involving database optimization, API integrations, and full-stack applications. I can help you: • Build REST APIs and backend services with Django, Django REST Framework, and FastAPI. • Improve existing applications through database query tuning, caching, and API performance optimization. • Integrate RAG chatbots and LLM features that use your business data. • Connect third-party APIs and implement JWT authentication. • Build React/Next.js dashboards and interfaces when your project needs full-stack delivery. • Deploy applications using Docker and AWS. Selected portfolio work: • Endrel — a FastAPI and Supabase API platform. • A WhatsApp Business messaging SaaS — backend and AI platform work. • Django, Elasticsearch, and Docker integration. My core stack includes Python, Django, FastAPI, PostgreSQL, MongoDB, Redis, Docker, and AWS. For AI integration, I work with LangChain, OpenAI, and Mistral; for frontend development, React, Next.js, and TypeScript. I can work with your existing team or take responsibility for development from requirements through deployment. You can expect clear progress updates, maintainable code, and practical discussions about scope and trade-offs. Send me your current stack, what you want to build or improve, and your biggest technical challenge. I'll help you identify a practical next step.
