About

I am a hands-on Full-Stack Software Engineer and QA Automation Specialist with a track record of delivering production-ready applications across e-commerce, AI-driven deployment automation, secure API migrations, and Stripe-based billing platforms. I design clean, modular code with security in mind, including AES-256-GCM encrypted secret vaults and feature verification against acceptance criteria before release.

With 25 years of precision engineering experience in FAA air traffic control, military electronics, and federal QA, I bring a disciplined, methodical approach to software development. I excel at automated testing (Python unittest, Jest, Playwright), live usability testing on deployed apps, and robust CI/CD workflows. I’m open to remote roles with companies outside Uganda and enjoy collaborating with global teams to ship reliable software.
