About

I like building things that are useful.

I work at the intersection of AI and software engineering — not as separate interests, but as one practice. Most of what I build is either a system that makes a decision (an agent, a ranking model, a verification pipeline) or the infrastructure that lets that system run reliably in production.

I currently work at Tata Consultancy Services, embedded with UBS, where I build production AI agent systems and the scalable backend platforms they run on. That work has shaped how I think about software in general: an AI system is only as good as the engineering discipline around it — the APIs, the monitoring, the deployment pipeline, the verification step that catches what the model gets wrong.

Outside of that, I build my own projects — from a custom operating system written in C and assembly, to developer tools, to small products I ship end to end. I write about what I learn along the way, because the parts worth remembering are usually the ones that only become obvious after something has shipped.
