SlackAbout
I build software that ships. Over the past seven years I have worked across the stack, React and Next.js on the frontend, Node and Rust on the backend, Solana and EVM on-chain. Most of my time goes toward products where speed, reliability, and clear UX actually matter: DeFi protocols, data platforms, and developer tools.
Before Web3 I spent years in traditional fullstack roles, which is where I picked up the habit of owning a feature from design through deployment. I like small teams, tight feedback loops, and shipping weekly.
My development environment is built around AI. Claude Code and Codex run inside custom agent pipelines I built for planning, code review, security audits, and QA. I ship faster and catch more bugs because the tooling does the repetitive thinking. If you need a technical co-builder who works at AI speed with human judgment, book a call and let's figure out what we can build together.

- 14 / 29 findingsIncluding 3 Critical-severity bugs, in a seeded capstone audit
- 6 working exploitsProof-of-concept attacks written, executed, and verified against fixes
- Self-correcting analysisDowngraded my own Critical finding after a PoC disproved it, then documented why
- End-to-end verificationPatched every confirmed bug and re-ran tests to confirm the fix held
