About Me

I'm a software engineer with a strong track record of delivering scalable applications across web and mobile. I've delivered production systems using stacks ranging from PHP and MySQL to React Native and AWS.

I focus on developer experience, maintainability, performance—cutting response times from 10s to 10ms, upgrading legacy platforms, and building claim payment authorization flows. I've developed features and validations in mission-critical internal tools, including premium rate table and client YTD process, used by thousands of employees supporting millions of users.

I also play a key role in a cross-platform, public-facing product - owning parts of its architecture (app monitoring, localization, CI, push notifications, and component library) and building half of its features using Expo, TypeScript, and tamagui (a Tailwind-like styling system for React Native).

Outside of work, I compete in coding challenges with Python, and I've earned top placements in hackathons and game jams.

Blog

This section is my personal study journal. Each day, I document something I've explored or built—whether it's a new tech concept, a design pattern, a tricky bug, or an unexpected insight. The goal is depth over volume: one meaningful takeaway a day is worth more than 20 forgettable ones.
