1. PSE Innowacje

   Senior Software Engineer

   since January 2025, full-time, Wrocław

   I led the proof of concept of an app that models and visualizes high-voltage power lines, and now we are growing it into the production system. I lead the architecture of the whole thing, frontend and backend. The frontend is Angular 19 and GoJS, and I drove the migration to GoJS 3. I designed the backend layer in Quarkus: batch processing, REST API, hexagonal architecture, Oracle tuning. In a team of five I onboard new engineers, set standards and the testing strategy, and review code.

2. Media Hunters

   Tech Lead

   September 2023 to December 2024, self-employed

   I was responsible for several long-lived web apps, from the code to the architecture decisions. I designed and evolved a multi-tenant SaaS platform. I introduced CI and tests in Jest and Cypress. I built the interfaces to WCAG. I led a small team and reviewed its code.

3. Transition Technologies MS

   Software Engineer

   September 2022 to August 2023, self-employed, remote

   A sandbox where electricians design and validate complex diagrams, high-voltage towers among them. I kept the graph-shaped UI state in NgRx. I implemented WCAG 2.1 in a diagram-heavy interface: keyboard, screen readers and focus management.

4. Cobiro

   Frontend Engineer

   February 2022 to August 2022, self-employed

   I moved a legacy frontend towards hexagonal architecture in small steps, keeping production stable. I helped introduce CI. I built feature flags for experiments and gradual rollouts with fast rollback.

5. Roche

   Frontend Engineer

   January 2021 to January 2022, contract, remote

   Internal apps where researchers analyze and validate clinical data. A regulated environment with little tolerance for errors. I made them faster with route-based lazy loading and leaner API usage.

6. BRAINODE

   Junior Frontend Developer

   August 2019 to December 2020, contract, hybrid

   A high-end shop with real-time 3D product views, in Angular and Three.js. I helped build a custom WebGL rendering layer. I implemented real-time currency exchange over WebSockets that holds up on unstable networks.
