A 24-agent AI org that develops my codebase 24/7.

Inside Trevion, headless Claude agents in isolated git worktrees plan, code, test, and open pull requests around the clock. Every change lands as a PR — a human reviews and merges; nothing ships itself.

03About

The engineer behind Legen.

I design and ship production-grade AI systems end-to-end — platforms, not features. Over 3+ years I've independently architected, deployed, and maintained 10+ systems: agentic AI pipelines, field-service CRMs, autonomous outbound engines, AI voice coaching, and the infrastructure underneath them.

My focus is agentic AI done rightLLM-powered systems that coordinate deterministic workflows with state machines, human approval gates, and authorized scopes enforced in code.

I think in systems: streaming pipelines, OLTP/OLAP separation, observability, audit-logged state transitions, and Docker/CI/CD deploys. Final-year CS (B.Tech 2026), applying theory directly to production.
