Core Expertise:
Philosophy
Less is More
The best code I've written is no code at all. Every line is a future maintenance cost—I think carefully about adoption, rollout, and whether complexity is justified.
Build to Learn
In personal projects, I push boundaries and experiment at the edge of overengineering. It's how I learn, grow, and stay excited about building things.
