Building reliable systems from idea to production.

About

I’m a software engineer who enjoys turning ideas into reliable, usable products. I like owning things end-to-end — from designing the architecture and writing the code to debugging, optimizing, and shipping the final product.

I enjoy working close to the problem, understanding why something works (or doesn’t), and finding simple solutions to complex problems. Most of my projects sit at the intersection of software, AI, automation, and the web, where I can experiment with new ideas while still focusing on solid engineering. I learn by building, breaking, debugging, and rebuilding. Whether it’s a side project or something meant for real users, I care about writing maintainable code and actually getting things shipped.
