Hello, I'm Samuel. I'm the hands-on engineer behind the CTMFB mobile banking app and upcoming business banking platform; shipping TypeScript, React and React Native experiences for 30K+ users. I also lead gameplay engineering at Darkstar Games, building Unity-based multiplayer worlds with cinematic storytelling.
About me
I’m a full-stack engineer with a Computer Science background and 5+ years building production software across fintech and gaming. Today I lead the engineering behind the CTMFB consumer mobile app and the upcoming business banking platform, shipping React Native and Next.js experiences used by tens of thousands of customers.
Outside fintech, I serve as Assistant Director of Engineering at Darkstar Games, designing Unity gameplay, AI systems, and cinematic tooling for our MMO. My toolkit spans TypeScript, React, React Native, Next.js, Firebase, Supabase, C#, Unity, and GitHub Copilot pro; and I enjoy pairing AI assistance with rigorous testing to move fast without breaking things.
Beyond shipping products, I mentor developers, teach web fundamentals, and explore creative outlets like acting and storytelling. I’m also actively learning German and sharpening my French while diving into history and philosophy for inspiration.
