About Me

Passionate developer creating digital experiences that matter

💼Open to contract & freelance work

Hello! I'm Thomas Musengwa

I'm a passionate full-stack developer with 7+ years of experience crafting digital experiences that drive business growth. My specialization is in building web & mobile products to transform complex challenges into elegant, accessible solutions that delight users and empower development teams. I believe in writing clean, maintainable code and creating applications that users love.

From Walmart's pickup towers to UnitedHealth's design systems, I've delivered high-impact applications that transform how millions of users interact with technology. Additionally, my efforts have saved my employers over 50,000 development hours, over $7 million in labor costs and over 3 million customer hours.

When I'm not coding, you'll find me exploring the coast and mountains of Maine, working on my 15' Chevy SS, or organizing pick-up games of Counter-Strike 2.
