I am Olubayo Samuel Olalekan, a Master’s student in Electrical Engineering at Universität Rostock with a focus on wireless communications, localisation, multipath propagation, and experimental measurements, and a growing research interest in resilient 5G/6G connectivity systems.
I currently work as a Research Assistant at the University of Rostock, conducting simulation-driven and measurement-based research on BLE localisation and channel sounding in multipath-rich environments. I combine a solid theoretical foundation in ranging and velocity estimation with hands-on experience in Linux-based testbeds, embedded systems, and data analysis.
Alongside research, I have spent more than a decade in technology leadership: CTO roles, founding an e-learning platform that reached thousands of young Africans, and delivering software and hardware for clients on three continents. I am a PTDF-DAAD scholar, and I am building my career in the German engineering industry.

I have had the pleasure of working with Sam as a client for my own website and as a collaborator on several shared projects. As a Backend and WordPress Developer, he is in a league of his own.
When he built my personal site, he brought so many ideas to the table to ensure the clean interface we had. He ensured the security was watertight and, most importantly, structured the CMS so that I have total control. He was also proactive enough to recommend an upgrade years later to keep me aligned with best practices, rather than waiting for things to break.
