Summary
🤩
Rockstar🎓
Top SchoolDaniel Maslowski is a pragmatic full-stack software engineer with 11 years of experience building web, cloud and embedded systems from Essen, Germany. He blends frontend and backend work with DevOps and firmware expertise—recently migrating the PSLab desktop app to PyQt5 and improving its documentation build pipeline. His background spans cloud migrations and infrastructure (Terraform, Docker, Kubernetes), backend services and multimedia processing at companies like img.ly and Klarna. Daniel also contributes to low-level projects such as oreboot, adding UART/debug support and QEMU integration, reflecting a rare comfort with both high-level web stacks and board-level firmware. He studies informatics and IT security, and favors open-source solutions that avoid license/patent roadblocks. Colleagues benefit from his practical problem-solving: he routinely moves legacy systems to modern, maintainable architectures while keeping an eye on reproducible deployment.
