AI Research Engineer · Leoforce

I'm an AI Research Engineer at Leoforce, building multi-agent systems, the orchestration patterns, tool use, and routing that make agents actually work together. I stay close to what's new in agents and write about what holds up. Before that, two years building RAG systems for 60k documents at ANZ, and a patented DL model in the construction domain at IIT Bombay.

Writing

01

I write about AI agents, what works and what breaks. Failures, tricks, and whatever's new that's actually worth knowing.

Most popular AI agent repos are weekend projects

I read the source of every popular open-source AI agent framework. The load-bearing idea in each is small, and the parts that matter in production are exactly the ones that don't go viral.
