About

I build full-stack web applications and AI systems - agents, MCP servers, LLM integrations, and the plumbing that makes them reliable in production. Before software, I spent six years as a mechanical engineer designing autonomous mobile robots, automation systems and production hardware. That is the reason I understand what engineering software is actually for, and it is what I bring to teams building tools for engineers and manufacturers. I also work with Solana and web3 infrastructure.

Currently Product R&D at CodeCrunch Techlabs and Lead Engineer at BlockchainHQ. Before software, six years designing autonomous mobile robots and automation systems.

AI Can Already Exploit Your Smart Contract for $1.22. That Number Is Falling.

Anthropic's red team priced agentic exploitation at retail: $1.22 to scan, $1,738 per vulnerability identified, $109 net profit. AI agents went from 2% to 55.8% exploit success in 12 months. Two live zero-days found Best@1. The audit window is closing.

Claude Wrote a Browser Exploit. Anthropic Published the Transcript.

Opus 4.6 wrote a working exploit for Firefox CVE-2026-2796 from scratch - addrof, fakeobj, a WasmGC pivot, fake ArrayBuffer, full RCE. Two successes in 350 attempts. Every other model: zero. The success rate isn't the story; the threshold being crossed is.

Cloudflare Shipped Enterprise MCP Governance. The Protocol Doesn't Have It Yet.

Cloudflare runs MCP for 200+ employees in production: server portals, Code Mode (99.9% token reduction), shadow MCP detection, and AI Gateway. Every one of those features is listed as an open gap in the official 2026 MCP roadmap. The vendor layer is ahead of the spec.
