Rockstar🎓
Top SchoolOliver Hahm is a Professor and IoT systems engineer with 15 years of experience researching and building wireless network protocols and operating systems for constrained devices. As a co-founder and long-time maintainer of RIOT, the widely used open-source OS for the Internet of Things, he blends low-level embedded systems work (network stacks, IPv6, radio configs) with academic rigor. He has a track record bridging industry and research—roles at Inria, Zühlke and industry testbeds—plus a PhD from Université Paris-Saclay. An open standards advocate, he’s known for pragmatic fixes that improve safety and interoperability (e.g., hardening IPv6 and cryptographic code) rather than glamour features. Based in Frankfurt, he combines hands-on firmware expertise with teaching and project leadership across European research collaborations.

Sep 2010 - Dec 2022
RIOT - The friendly OS for IoT
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:3 releases, 105 reviews, 2514 commits in 12 years 4 months
Contributions summary:Oliver's contributions primarily revolve around modifying and enhancing the RIOT operating system, focusing on low-level hardware interactions and networking functionalities within the context of IoT devices. The commits include improvements to cryptographic libraries by replacing `printf` calls with debugging statements, removing non-ISO compliant macros, and adjusting the channel configuration of IEEE 802.15.4 radios. The user also integrated IPv6 functionality by adding checks for different address types and improved the IPv6 stack by addressing null-pointer dereferences. Finally, the user worked on adding network layer features such as configuring the maximum size of an IPv6 datagram.
