NepalWhat I'm looking for
I've delivered 80+ full-stack projects for global clients through Upwork, maintaining a 100% Job Success Score. I build production-grade Python services and AI-powered workflows that are clean, tested, secure, and built to last.
My work spans Django, DRF, FastAPI, and Flask APIs alongside React and Next.js applications. I've optimized PostgreSQL, MySQL, and MongoDB data models, improved query performance, and built user-facing healthcare dashboard components for 10K+ users.
I integrate OpenAI, LangChain, GenAI, and RAG pipelines into chatbots, search workflows, and generative applications. My open-source work includes an IG.com delta-hedging platform, a TTS/STT content summarizer, and deterministic quantitative routing architecture.
I've also driven AWS CI/CD, authentication, security, testing, API design, performance, accessibility, and SEO across freelance and product teams.
