Hi, I'm Mars — Full Stack Software Engineer
I build fast, accessible web experiences.
About
I'm a full-stack software engineer with a deep passion for problem solving, working across Java and JavaScript frameworks along with SQL and NoSQL databases. Most recently I spent over three years as a Software Engineer in Test at Mastercard, building automated regression suites and monitoring infrastructure that kept production systems reliable.
Today I'm the founder and lead engineer behind Donada, a Cardano-based NFT platform where holders can rent out their assets to earn yield and become eligible for scheduled, automatically-paid prize draws. As a solo developer, I own the full stack — smart contracts, frontend, and infrastructure.
When I'm not building, you'll find me biking, gaming, tinkering on hobby coding projects, or indulging in general nerdery 🤓.
