Building products that people love

01About Me

I’m a Senior Full Stack Software Engineer who thrives on creating products that users can fall in love with.

At Sazmining, I pioneered the industry’s first Bitcoin Mining as a Service platform integrated with the OCEAN decentralized mining pool, delivering real-time transparency and non-custodial payouts using TypeScript, Supabase, and React. I design scalable systems, automate financial workflows with Node.js microservices, and lead teams to elevate engineering standards while mentoring others. I’m driven by a vision to build products that not only solve problems but also spark joy and advance human potential.

02Philosophy

Growth Through Technology

I've seen firsthand how technology can solve real problems and create meaningful impact. Every line of code I write is an opportunity to build something that matters, every system a chance to make someone's life better.
