Building scalable solutions that matter

I'm a passionate Full Stack Software Engineer with 3+ years of experience building scalable fintech microservices, compliance systems, and developer tools. I specialize in TypeScript, GoLang, React, and cloud infrastructure — with a focus on performance, reliability, and user impact.

Currently at Signzy, building compliance and fintech microservices that power digital onboarding at scale. Previously at Advanced Millennium Technologies where I helped serve 10M+ users across 40 countries.
