What I'm looking for

I seek a technical role focusing on embedded software development and automated HIL testing, in collaborative teams that value robust documentation, test automation, and continuous improvement.

I am an experienced embedded software engineer with over 5 years of hands-on expertise in C, C++, Python, embedded system testing, and hardware-in-the-loop simulation. I have designed and executed comprehensive test suites, automated build and test pipelines, and produced clear, auditable documentation supporting avionics, automotive, and railway projects.

My achievements include creating test suites that achieved full functional/code coverage, implementing Jenkins automation with Grafana reporting, and developing interactive documentation and internal tooling to increase visibility and reproducibility. I prioritize reliable, well-documented solutions and effective collaboration across multidisciplinary teams.
