About

As a software engineer who has shipped numerous apps and SaaS products, I understand how challenging it is to create something viable. The truth is, we’re not just building products—we’re building solutions to problems. And since every problem has its own audience, the first step is finding those people and building with them. That’s the only way to create something people genuinely want.


I’m a back-end-first engineer—building systems and digitalizing businesses are at the core of my expertise. While I consider myself a stack-agnostic engineer, I’m most familiar with the MERN stack and Python’s Flask framework.
