What I have worked on so far

No empty numbers — the areas, projects and responsibilities that shaped how I work.

  1. 01 / Enterprise environments

    QA and data reliability at scale

    Projects delivered in environments connected with organizations such as PwC, Roche and E.ON: test automation, data quality and cloud platforms inside regulated, multi-team organizations.

    • UI, API and data test automation (Python, PyTest)
    • Data validation and a data reliability platform on AWS
    • Working in CI/CD pipelines and formal release processes
    • Collaboration with international, distributed teams
  2. 02 / Own products

    Apps taken from idea to the app stores

    Projects owned end to end: architecture, code, testing, release and maintenance — including the IZAPzoo loyalty platform and the ThomasSeeker application.

    • Android and iOS apps with a cloud backend
    • Admin panels and role-based permission systems
    • Releases to Google Play and the App Store
    • Maintenance and further development after launch
  3. 03 / Web & automation

    Websites, integrations and process automation

    Websites and web applications for companies, plus automations that take repetitive manual work off people's plates.

    • Company and brand websites (including Cammanvideo)
    • API integrations and data synchronization
    • Python automations and scheduled jobs
    • Technical SEO and performance foundations
  4. 04 / Local support

    Computer service and IT support in Bydgoszcz

    The practical side of IT: from diagnosing a laptop to configuring an entire office — for companies and private clients.

    • Computer diagnostics and repair
    • Networks, Wi-Fi and printers in homes and offices
    • Microsoft 365 and Google Workspace
    • Backups and security basics

Organization names describe environments where projects were delivered — they do not imply endorsement or formal partnership. Confidential projects are described in anonymized form only.
