Alena MartinkováFull stack developer focused on backend

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 first diagram to production

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.

Currently building at Rankacy

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.

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.

The stack I trust, and how I run it

Backend & platform engineering

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

  • 01Python · FastAPI
  • 02PostgreSQL · SQLAlchemy
  • 03Redis · RabbitMQ
  • 04API design & event-driven services
product.tsx

Product & frontend

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

  • 01React · Vue
  • 02State, forms & real-time UI
  • 03Close collaboration with design & product
  • 04Accessibility & performance
delivery.yml

Delivery & reliability

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

  • 01CI/CD pipelines
  • 02Docker · Kubernetes
  • 03PyTest · Cypress · integration tests
  • 04Metrics & logging
leading.md

Leading & AI-assisted work

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

  • 01Mentoring & code review culture
  • 02Specs, estimates & planning
  • 03AI in the loop where it genuinely speeds us up
  • 04Architecture decisions stay with engineers

Projects I’m glad to put my name on

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

E-sports analytics platform

Rankacy

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
