Summary
🤩
Rockstar🎓
Top SchoolMarcin Chalczyński is a senior backend engineer with a decade of experience building resilient server-side systems for IoT, automotive and web products from prototype to production. Based in Cologne, he has driven OTA and device-cloud projects—pushing mender.io from POC to a public 1.0 and evolving its on‑prem offering into a SaaS—while working across architecture, APIs and day-to-day Golang microservices development. His background spans low-level embedded firmware to Erlang-based asynchronous services and modern containerized backends, giving him a rare end-to-end perspective on connected-device stacks. Frequently the team technical lead, he combines pragmatic system design with hands-on coding, mentorship and operational awareness. Colleagues rely on him to turn fuzzy requirements into maintainable, deployable systems that bridge hardware and cloud.
