Patryk Andrzejewski is a process engineer with 11 years of hands-on experience bridging manufacturing engineering and software development, based in Wrocław, Poland. He has led process improvements and quality systems for battery manufacturing at LG Energy Solution and now applies that systems-thinking to process engineering at GTHR Poland. Alongside his engineering career he contributes to open-source projects as a front‑ and full‑stack developer, with notable React/TypeScript work on Saleor’s dashboard and UI/archiving fixes for Matomo. His blend of mechanical design, PFMEA/control plan creation, and backend integrations (Magento/Vue Storefront APIs) gives him a rare cross-domain perspective on product, data and production flows. Comfortable moving between SolidWorks/CAD, SPC/MSA metrics and modern web stacks, he’s skilled at turning complex technical constraints into practical, auditable solutions. Colleagues describe him as pragmatic and detail-oriented, with a track record of shipping both production processes and polished UI features.
