Summary

I’m a full-stack engineer with 16 years of React, Node, and TypeScript under my belt, and I figured out a long time ago that AI is the best pair-programmer I’ve ever had. I’ve evolved into an AI early adopter who’s as comfortable tuning a prompt as I am debugging a race condition. I’ve built my own workflows for AI-driven code reviews and bug squashings because, frankly, life’s too short for manual drudgery. I'm not some 'resisting relic' clinging to the old ways—I’m out here building the future with high-quality code and a sprinkle of machine intelligence. Fast, scalable, and just a little bit futuristic.
