I'm a product engineer who cares as much about why something is built as how it's built. With 11+ years spanning backend systems, cloud infrastructure, and mobile development, I bring technical depth that's grounded in real product thinking.

I've led engineering teams, shaped technical roadmaps, and shipped products across telehealth, logistics, fintech, and e-commerce. My focus is always on the end user — what makes a product great isn't just clean code, it's whether it solves a real problem and feels good to use.

I work at the intersection of engineering and product: translating business goals into scalable, maintainable systems, and ensuring what we ship is something users genuinely want to come back to.

Outside the terminal: fueled by a Coffee, obsessed with clean architecture, and always looking to make things simpler than they need to be.
