I build agentic systems that remember and keep working for days — on a schedule, not a prompt.

01About
I'm a Senior Data Scientist at OLX, with a growing identity as an AI Engineer. I build agentic systems for a marketplace — the harness they run on, the memory they keep, and the personalization layer underneath.
I came to this from aerospace engineering and robotics, then spent four years at Farfetch on search, NLP, and knowledge graphs. That leaves me T-shaped: broad enough to move across the stack, deep enough to ship AI systems that stay observable and scalable in production.
Off the clock, I build for my own house — home automation, CLIs, and the occasional robot.
If you're working on agentic systems, or just want to geek out about AI architecture, let's connect. The full CV is on LinkedIn.
