GNSS sensor project: - Developed test cases, implemented & maintained tests. - Clarified requirements with stakeholders. - Implemented features for device interaction & management library. Visual & laser scanner project: - Migrated device library build setup (pipenv+setup.py+tox -> uv+setuptools+nox) & updated docs. - Introduced Devcontainer for the library environment. - Created a manual verification suite to extend automated tests.

I was responsible for building from the ground up performance tests for a cloud system.

As a member of QA team, I was responsible for: * Firmware test automation * Test maintenance * Code review participation * Gitlab CI pipelines management Automated tests allowed performing a fast (less than two minutes) smoke test for every single build, indicating if it is ready for robust testing. Dropped overall testing time from a week to less than a day, with even more precise results. Gitlab, Python, pytest
