About Me

I'm a Software Engineer at Trustabl AI, working on AI agent reliability and tool hardening. Previously at Hooli Software and Carbonetes, where I shipped open-source security scanners used by real organizations.

I'm a member of the Jenkins CI GitHub organization, and I use AI-assisted engineering (Claude Code) daily to ship faster without cutting corners.

Technologies I work with regularly:

  • TypeScript / JavaScript
  • Go & Python
  • Next.js & React
  • PostgreSQL
  • Docker & Bash
  • CI/CD (4 platforms)
