01. About

I'm a software developer who enjoys building a wide range of tools and applications — from system-level CLI utilities that monitor hardware, to mobile apps with Flutter, and automation bots that bridge services together. I enjoy diving deep into how things work at every layer of the stack.

Currently focused on indie development, creating apps that I wish existed.
