Founding Engineer @Experiment Labs | AI-Native Products & Backend Infrastructure

About

I like building things end to end. Not just features, full systems: the auth, the queues, the AI pipeline, the billing, the infra. If it ships and works in production, that's what counts. Most of my work sits at the intersection of backend systems and AI, which is where I want to keep going. I'm drawn to problems where the engineering is genuinely hard, not just wiring APIs together. Built and shipped Crelyzor (https://crelyzor.hrshkshri.com/), an AI-native workspace I started because the tools I wanted didn't exist. Open to founding engineer or early engineer roles at startups.
