Engineering systems
that scale with intent.

I'm a Senior Software Developer with 6+ years building backend systems and APIs that power real-world products at scale. My work sits at the intersection of technical precision and product impact.

I specialize in .NET Core backend engineering, scalable API architecture, and optimizing relational databases under real production load. I care about code that is maintainable, systems that are observable, and solutions that move the needle.
