I build and evolve complex software systems that are meant to last.

With more than 20 years in software development, I’ve worked across the full lifecycle of long-running products: from early architecture and vague problem statements to scaling, reliability, performance and sustained delivery over many years.

My work often sits at the intersection of engineering, product thinking and people management, where judgment matters as much as code.

I’ve owned critical technical domains, shaped architectural direction and acted as a decision-maker in cross-functional environments.

I’m comfortable navigating ambiguity, aligning technical choices with real constraints and helping teams move from ideas to production without losing quality or momentum.

What I consistently focus on:

My strongest experience is in web development, where I’ve spent years building and running complex systems in production.

When needed, I work confidently with low-level, performance-sensitive systems, where efficiency, correctness and careful design truly matter.

I enjoy working in product-oriented environments where there’s an understanding of WHAT needs to be built and WHY.

I’m flexible in HOW solutions are delivered — from moving fast with imperfect constraints to prioritizing quality, longevity and correctness when the problem demands it.
