Expertise

Full-Stack Engineering

I've spent most of my career building across the full stack in fintech. The part I care most about isn't whether the feature ships. It's whether the code is still understandable six months later, by someone who wasn't in the room when it was written.

AI-Native Development

I actually use AI coding tools in production. I've built internal frameworks around spec-driven prompting and structured context-setting, and presented the approach to my engineering team. It's part of how I work, not a side experiment.

Fintech Domain

Eight years building digital banking products. Credit systems, core integrations, compliance-heavy features. Working in this space keeps you honest: data integrity isn't optional, and the cost of getting things wrong is real.

About me

I care about writing good software, but I am equally focused on what that software needs to do for the business. Engineering quality and delivery speed are not opposites. Finding where they meet is usually the more interesting problem.

I bring that same thinking to distributed systems and scalable architecture, where most of my deeper curiosity lives. The web moves fast, and I take keeping up with it seriously: understanding what is worth adopting, why, and how it helps teams ship better software.
