What I'm looking for

I'm targeting Technical Leader, Software Architect, Engineering Manager, or Staff / Principal Backend Engineer roles.

I’m a Software Engineer and Tech Lead who enjoys building systems, solving complex problems, and thinking about what happens beyond the code.

I write about software architecture, backend engineering, distributed systems, AI, scalability, resilience, and the decisions that make—or break—real-world software.

I’m interested in the uncomfortable questions: What should we build? What shouldn’t we build? When is a solution actually correct? And what happens when the system meets reality?

Code is the output. Engineering judgment is the craft.
