independent web studio
I build production web products with Next.js and NestJS — and I stay with them through deployment, debugging, and the parts that only break at 2am on real infrastructure.

What I focus on
I enjoy building end-to-end products that are clean, scalable, and maintainable. Most of my work is shipping features, wiring frontend to backend, and supporting production deployment on AWS.
Ship it, then own it
Writing the feature is half the job. I stay through deploy, logs, and the incident that shows up a week later.
One system, not many
Reusable primitives and consistent conventions beat clever one-offs. New requirements should cost less over time, not more.
Boring infrastructure
I reach for the well-understood AWS building blocks first. Interesting architecture is a cost, not a feature.

Two kinds of work
Product engineering at a company, and client sites I design, build, and deploy myself. Different constraints, same standards.
Product engineering at Pionero JSC — client-facing platforms and internal tools, most of them running on AWS.
- Built the streaming transcript UI and kept updates stable under a continuous socket feed.
- Handled reconnection and out-of-order chunks so the transcript never visibly jumped.
- Integrated with backend inference services hosted on Azure.
