What I'm looking for

I’m looking for remote B2B work where I can own production features end-to-end with security-first engineering, agent-assisted implementation, and rigorous review. I want teams that value quality gates, fast iteration, and clean deploys.

I’m an Agentic Engineer and founder who builds and ships production software I can own end to end—from spec and architecture to security and deploy. Coding agents handle most implementation, while I make the design calls and review every diff before it ships.

I built and shipped The Cell, a Flutter and Supabase mobile app, to iOS and Android under my own US LLC. I owned the architecture, security, subscription billing, push, analytics, and crash reporting, and I migrated the backend from Firebase to Supabase mid-build with an RLS-first schema.

My workflow is built around an agentic quality gate: I read every diff and catch failure modes like hallucinated APIs, scope creep, over-engineering, and tests being quietly weakened. I also run a self-hosted OpenClaw gateway on my VPS so agents can work without being tied to a single IDE.

With an OWASP background from my cyber security degree and production security practices like certificate pinning, scoped API keys, and secret hygiene, I focus on shipping safely—not just quickly. I’m available now for remote B2B contract work through my US LLC.
