Python Full Stack Developer | AI Conversation History (FastAPI, OpenAI)
Second time working together and he killed it again. He got our AI conversation history system up and running with zero issues. If you need a solid python dev who actually understands full stack architecture, he’s your guy. Will definitely keep up the relation with him

Full-Stack Python Developer | Optimize LLM API Responses (OpenAI + FastAPI + SaaS)
Really happy with the work. Our SaaS application's AI features were lagging and returning messy formatting, but he jumped right in and cleaned up the OpenAI, LLM pipeline, and FastAPI integration. The Next.js frontend now loads the AI responses much quicker and the outputs are finally consistent. Easy to work with and definitely rehiring him for the next task.

✅ Python Full Stack Developer | SaaS, MVP's & AI Web Developer
✅ 100+ AI Agents and Automation Workflows Delivered
I’m a Full-Stack Developer specializing in Python Full Stack Development, Next.js, SaaS Development and AI-powered web application development.
I leverage modern AI-assisted development workflows using tools like Cursor, Claude, and OpenAI so what traditionally takes weeks ships in days. I work with founders and product teams who need a Full-Stack Developer that actually understands the product. Over the past 8+ years I have engineered Python-powered SaaS platforms, AI web apps and multi-agent systems for fintech, healthcare, e-commerce, real estate, EdTech and B2B startups.
💻 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 𝗧𝗲𝗰𝗵 𝗦𝘁𝗮𝗰𝗸
As a Python Full Stack Developer I work across:
Frontend: Next.js, React, TypeScript
Backend: Python, FastAPI, Django
