Software engineer and CTO.
I build practical software that helps businesses operate better — especially in finance, operations, and SaaS.
I focus on simple, reliable systems that solve real problems and ship quickly.
- Build and scale web and mobile products (Rails, React, Flutter)
- Design multi-tenant SaaS platforms
- Improve performance, reliability, and architecture
- Build finance and operational tools
Finance, decision-making tools, and software that directly improves how a business runs.
If there is a real problem to solve, I’m interested.
I help teams:
- turn ideas into working products quickly
- simplify complex systems
- ship consistently
Open to freelance, consulting, or senior engineering roles.
