whoami

Most engineers either build or break. I do both — that's the whole point.

I architect autonomous, multi-agent AI systems and the security that keeps them honest: offensive tooling, exactly-once payment integrity, and platform backends proven at scale. 1,715 commits across public and private work say it better than a tagline.

~/ai
Agentic AI

Multi-agent, self-adversarial systems with the ReAct loop — METIS, KaziAI, GenJob. Reasoners that plan, act, and coordinate at runtime.
~/security
Build & Break

Offensive tooling and defensive integrity. A 10-round audit that surfaced 22 bugs incl. criticals — HTML injection, broken auth gates.
~/scale
Platform Backend

Django/FastAPI/Go services at scale — a 12.6M-record portal, real-time marketplaces, and a +60% throughput rewrite in Go.
~/identity
Decentralized ID

Verifiable credentials and trust graphs — LinkedTrust: Hyperledger Aries, AnonCreds, W3C VCs, the AT Protocol.

what I can build for you

Hire me for the hard parts — the autonomous systems, the security that proves they're safe, and the backends that don't fall over. Outcomes, not demos.

Agentic AI Systems

Multi-agent, self-adversarial systems on the ReAct loop. Reasoners that plan, act, and coordinate — shipping outcomes, not chatbots.

METIS · KaziAI · GenJob

Security & Audits

Offensive testing and defensive integrity. I find the holes — HTML injection, broken auth gates, payment races — before attackers do.

I build autonomous AI systems. Then I attack them first.
