About

I build production-grade systems at the intersection of full-stack engineering and AI - shipping everything from RAG pipelines and LLM agent workflows to scalable APIs and backend infrastructure. Currently at Oncourse AI as a Full-Stack Engineer, where I've: - Cut API latency by 50% and eliminated recurring failures across critical endpoints - Built AI workflows (RAG chat, quiz agents, content pipelines) that replaced manual learning and support flows - Scaled SEO infrastructure to 4M+ impressions in 3 months through automated research and publishing systems - Designed a centralized content system reducing duplication across questions, lessons, and media Before that, as Founding Engineer at Saathi.app, I owned the full backend - reduced latency by 60%, scaled data pipelines to 1M+ records, and built LLM orchestration systems for real-time travel planning. I'm a multi-hat engineer. My core is backend and AI systems, but I ship end-to-end when the problem needs it - from infrastructure to frontend to growth tooling. 🔍 Open to Full-Stack, Backend, and AI Engineering roles where I can own systems and ship fast.
