Summary
🤩
Rockstar🎓
Top SchoolMarkus Lassila is a Senior R&D Engineer based in Tampere with a strong embedded-systems pedigree and over a decade of hands-on experience in networking and protocol-level software. After leading teams and designing enterprise software at M-Files, he returned to embedded work at Nordic Semiconductor, contributing reliability and performance fixes to the widely used nRF Connect SDK—especially improving UART handling, serial LTE modem timing, and TLS/UDP behavior. He combines system-level troubleshooting with practical refactoring, bundling AT commands and streamlining data paths to make real-time communication more robust. His background includes protocol integration, IPv6 migration and real-time monitoring from roles at Nokia and Nokia Siemens Networks, reflecting deep experience across telecom-grade and product-focused engineering. Markus pairs academic grounding in embedded systems with a rare mix of managerial and low-level engineering skills, making him effective at both shipping features and hardening system reliability.
