Hi, my name is

Dennis Trautwein.

Nice to meet you!

I'm a physicist working as a software engineer based in Switzerland currently specializing in peer to peer systems as part of a PhD endeavour.

About Me

Hi! I'm Dennis, a software engineer based in Switzerland who enjoys building things that live on the internet and also power the internet.

Shortly after graduating from Christian-Albrechts-University, I joined the engineering team at where I developed and successfully launched the Mercedes Benz Mobile SDK. Then I became an industrial PhD candidate and joined OriginStamp in Switzerland to explore peer to peer systems in trustless environments.

Currently, I'm also funded by Protocol Labs with a two year PhD Fellowship for studying node heterogeneity in Peer-To-Peer networks, particularly IPFS and Filecoin.

Here are a few technologies I’ve been working with recently:

  • AWS
  • Kubernetes
  • ArgoCD
  • Golang
  • Terraform
  • Protobuf/GRPC
  • libp2p

Where I’ve Worked

Research Engineer @ Protocol Labs

Sep 2022 - Present

  • Study, design and propose measurement methodologies to quantify the healthy operation of libp2p protocols for IPFS, Filecoin and other platforms.
  • Propose metrics that help quantify the performance of networking processes and protocols.
  • Validate design proposals through simulation experiments and/or proof-of-concept distributed, large-scale testbed, or real-world implementations.
  • Contribute and lead implementation of protocol optimizations.
