Summary
🤩
Rockstar🎓
Top SchoolJan Mehnen is a founder and engineer with 15 years of experience building hardware-enabled manufacturing and automation systems, currently leading a stealth startup focused on next-generation European production. He combines a PhD-level background in production technology with hands-on work in avionics, fixed-wing UAV command-and-control, and sensor-driven automation from his role at mb+Partner. Jan is also an active back-end contributor to notable open-source projects in the IPFS/libp2p ecosystem, improving pubsub, HTTP API behavior, and test coverage for widely used Go libraries. His work bridges applied research—machine learning and CFRP heat conduction studies—with practical prototyping and production automation, from mobile runway systems to automated localization. Known for moving both atoms and bits, he thrives at the intersection of industrial strength and new technology, translating complex research into deployable systems. Based in Hamburg, he often blends deep technical detail with product-oriented execution and enjoys connecting with engineers who reimagine how things are made.

The go interface to ipfs's HTTP API
Role in this project:Back-end Developer
Back-end DeveloperContributions:9 commits, 3 PRs, 2 pushes in 1 year 1 month
Contributions summary:Jan primarily worked on implementing and refining the `pubsub` functionality within the go-ipfs-api library. Their contributions involved the design and implementation of data structures like `PubSubRecord` and `Subscription`, along with corresponding methods for subscribing, publishing, and canceling subscriptions. The code changes reflect a progression from an initial prototype to a more refined, yet still simplified, implementation of the pubsub feature, including changes to how the messages are handled. These changes involved base64 encoding, JSON decoding and the implementation of specific methods to handle the flow of information.
