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. I develop highly efficient, scalable and distributed backend systems that power seamless user experiences for the end consumers.
Shortly after graduating from Christian-Albrechts-University, I joined the engineering team at freiheit.com 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.
Here are a few technologies I've been working with recently:
- Golang
- Kubernetes
- Terraform
- Protoactor
- Protobuf/GRPC
- Azure
Where I've Worked
Industrial PhD candidate @ OriginStamp AG
May 2020 - Present in Kreuzlingen, Switzerland
- Work in a micro-service environment powered EBS in the AWS cloud.
- Introduced Terraform as an infrastructure as code solution.
- Introduced Hashicorp Vault as a key managment solution.
- Worked full stack along an Angular PWA, Hugo static site, Spring Boot micro-services, Ansible VM/NAS provisioning.
Some Things I've Built
Featured Project
Mercedes Benz Mobile SDK
As part of my work at freiheit.com I built the backend part of the real time event supply for the Mercedes Benz Mobile SDK. A status update of a vehicle (like opening a door) or sending a command to the vehicle goes through my code.
- Go
- protobuf/GRPC
- Terraform
- Kubernetes
Featured Project
Image-Stego
Steganography-based image integrity via embedding Merkle tree nodes into image chunks so that each chunks integrity can be verified on its own. This enables highlighting exactly which areas of a photo were modified which is an improvment over an image-wide "pass/fail".
- Go
- Merkle Tree
- Steganography
Featured Project
BEXUS
Participated in a Balloon Experiment for University Students. Developed, built and performed a space qualified experiment on a stratospheric research balloon as part of an official mission from the European Space Agency. Measured the angular distribution of charged particles in the atmosphere.
- Networking
- CAD
- Python
- GEANT4
Other Projects
Hashicorp Vault terminal UI
A prototype of a terminal UI that allows browsing through Vault's secret hierarchy tree. You can find a demo GIF at the PR to the official Hashicorp Vault Repository.
Repulsion
Repulsion is a tiny iOS game ajar to flappy bird. Read more about it on Ray Wenderlich where it got featured on the monthly readers app reviews. It is not on the AppStore anymore because I did not update it since 2016.
You Commit
I developed and shipped an iOS applications as part of my internship in New Zealand for tracking the performance of employees. This app included a syncing algorithm to the local Core Data database to remain fully functional offline. Demo-Video
