About

I build web products that earn their keep.

I'm a Senior Software Engineer with 7 years shipping production software at companies like Dentallab, Innospace Infotech, Square Health and Shohoz. I care about clean architecture, scalable systems, fast feedback loops, and code my teammates actually enjoy reading.

Full stack, end to end

Six years across React, Next.js, Angular, NestJS, MongoDB, Redis, AWS and Docker — comfortable owning a feature from VPC to pixel polish.

Ship for impact, not novelty

I optimize for the metric the business cares about: scale, conversion, dev velocity. Past work serves 200k+ users on Brritto, lifted Shohoz Food sales 150%, and cut developer dependency 30% on Jotno.

Open-source contributor

Contributor to PrimeNG with 19+ merged commits. Top 10% on Stack Overflow with 80+ answers in React and Redux.

Mentor & teammate

I mentor junior engineers, review thoughtfully, and write code my future teammates can read at 3am during an incident.

Selected Work

Case studies from products I've shipped

Each of these was production work with real users and real numbers — not tutorial clones.
