About

Karan Patel is a backend-focused full-stack engineer specializing in Python and FastAPI. He builds production APIs as an AI + Backend Developer at BonsAI Agents and delivered D&D Purchase, a live B2B buyer-seller platform, as an independent freelance developer.

I'm a backend engineer who cares more about whether a system actually works in production than how it looks in a slide deck. As an AI + Backend Developer at BonsAI Agents, I built and shipped 10+ FastAPI endpoints, cut average database response time by roughly 30% through indexing and query restructuring, and resolved 15+ production issues. Outside that, I've worked as a freelance full-stack developer — my strongest project, D&D Purchase, is a live B2B platform with separate buyer and seller workflows that I took from requirements to deployment for a paying client. I also build applied-AI tools on the side (RAG pipelines, document processing, AI agents) because I like understanding how new tools actually get used, not just how they demo.
