01about

I code. I lead.

I lead the backend of a CS2 analytics platform at Rankacy, and 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.

From frontend to team leadership

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.

How I work

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.

Leadership without micromanagement

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.

Backend & platform engineering

APIs, queues and data models that keep their shape under real load.

  • Python · FastAPI
  • PostgreSQL · SQLAlchemy
  • Redis · RabbitMQ
  • API design & event-driven services
02

Product & frontend

Full stack means the product has to work, not just the endpoints.

  • React · Vue
  • State, forms & real-time UI
  • Close collaboration with design & product
  • Accessibility & performance
03

Delivery & reliability

I like systems that don’t break at 2 am. Or worse — during a Friday release.

  • CI/CD pipelines
  • Docker · Kubernetes
  • PyTest · Cypress · integration tests
  • Metrics & logging
04

Leading & AI-assisted work

The whole team should understand the system — not one person holding it all in their head.

  • Mentoring & code review culture
  • Specs, estimates & planning
  • AI in the loop where it genuinely speeds us up
  • Architecture decisions stay with engineers

03work

Work that lives on.

A selection from product work and client deliveries. Most of it still runs in production — which is the part I’m proud of.

View platform

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.

  • Event-driven FastAPI services — match processing fanned out through RabbitMQ
  • PostgreSQL with millions of match records, Redis caching the hot reads
  • Runs on AWS, serving players worldwide
  • Subscription & billing flows built on Stripe

Visit portal

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.

  • Custom availability & reservation flow, no ready-made booking engine underneath
  • Public portal and back-office administration built as one whole
