Full-stack engineer.
Product builder.

I’m Alex, a senior full-stack engineer.

Since 2015, I’ve built products across ML monitoring, fintech, mobile apps, marketplaces, and backend systems—from the first line of code through launch and growth.

01. THE SHORT VERSION

I build products from scratch, then use customer insight and product data to make them better.

My work spans frontend applications, mobile apps, backend services, payments, and internal tools. I’ve launched consumer apps with more than 100,000 downloads and built the systems behind their growth.

I’ve also moved beyond individual contribution into product ownership and team leadership—managing onboarding work, running experiments, conducting UX research, and connecting technical decisions to measurable customer outcomes.
