Independent Fullstack Engineer focused on system reliability, internal tooling, and operational clarity.
I work on systems where failure is expensive.
My focus is on identifying brittle logic, reducing operational overhead, and improving how systems behave under real-world conditions. I’m particularly interested in the parts of systems that are usually labeled “temporary”, “manual”, or “good enough”.
Most of my work lives at the intersection of:
- Reliability
- Internal tooling
- Payment and data flows
- Developer experience inside production systems
- Debugging and improving failure handling in backend systems
- Reducing manual operational workflows through small, targeted automation
- Improving observability and clarity around critical code paths
- Contributing fixes and improvements to production-used open source tools
I prefer scoped, well-defined problems over large rewrites.
- TypeScript, Node.js
- React and Next.js (when necessary)
- SQL and document databases
- Event-driven and API-based systems
I value boring, well-understood technology when reliability matters.
I contribute to open source projects used in production, typically focusing on:
- Bug fixes
- Reliability improvements
- Clear documentation
- Edge cases that appear under load or failure conditions

I’m open to short diagnostic engagements and targeted fixes.
Quiet systems. Clear behavior. Fewer surprises.
