Architecture in practice
My daily stack is Python (FastAPI), PostgreSQL, Redis and RabbitMQ, with React in front. I care about clean architecture, tests that earn their keep (PyTest, Cypress) and observability you can actually debug from.

01about
As Backend Lead at Mesocort AI, I’m responsible for backend development across the company. I also take on client projects across the whole stack on the side. I’m big on architecture that still makes sense a year later, APIs that survive real traffic, and deadlines that hold.
I started in 2019 with agency work — e-shops, booking systems and internal tools for international clients — and grew from frontend through full stack to leading a team. Leading didn’t take the code away from me: I still write a good part of it myself.

Leading a team means clear specs, honest code review and mentoring without micromanaging. Outside the code I enjoy the creative side — anything that makes the product feel better to use.

02stack
One system. From the interface to infrastructure.
State · Forms · Real-time
REST · SQLAlchemy · Stripe
Event-driven · Async jobs
Data models · SQL
Cache · Fast reads
CI/CD · PyTest · Cypress
APIs, queues and data models that keep their shape under real load.
Full stack means the product has to work, not just the endpoints.
I like systems that don’t break at 2 am. Or worse — during a Friday release.
The whole team should understand the system — not one person holding it all in their head.

A selection from product work and client deliveries. Most of it still runs in production — which is the part I’m proud of.
Rankacy tells CS2 players what to improve. I run the backend that makes that possible — match ingestion and processing, stats APIs, subscriptions — mine from the first architecture decision to the last implementation review.
An industrial-supplies e-shop built as a fully custom system — FastAPI backend with a React storefront and admin: dynamic pricing, multilingual catalogue, ERP synchronisation.
A Booking-style reservation portal for spa stays, written from scratch in Laravel and React — the public web and the internal administration as one custom system. My last and biggest agency project.
