I got into programming by reverse-engineering games and hacking together tools to make my life easier—small scripts, terminal apps, and bots. That curiosity turned into obsession once I picked up Rust and Go. I’ve since built full-stack apps, AI systems, and even my own Redis clone. I thrive on solving real problems with clean, performant code, and I’m now looking to bring that energy into a backend engineering role where I can ship fast, learn fast, and break things (on purpose and for good reasons).…I got into programming by reverse-engineering games and hacking together tools to make my life easier—small scripts, terminal apps, and bots.
