Full-Stack Engineer · Product Builder · Systems Thinker
I design and ship production-grade software that scales.
I’m a full-stack engineer focused on building reliable, high-performance products for companies, startups, and businesses. I work end-to-end — from system design and APIs to polished user interfaces and deployment — with a strong focus on clarity, maintainability, and long-term growth.
I help teams build software that:
- ships fast without accumulating technical debt
- scales with users, data, and team size
- feels modern, clean, and intentional

- End-to-end product engineering (idea → production)
- Scalable backend systems & APIs
- Modern, performant frontend applications
- Developer tools and internal platforms
- Long-term systems built for growth and iteration
I don’t just implement features — I design systems, make sound technical trade-offs, and build software that teams can confidently evolve over time.
