Über mich

Berlin-based software architect & Rust engineer. Co-founded Seismiq GmbH (edge+AI earthquake sensors). A decade in Python, Rust for 6 years. I design and ship systems end to end — cloud architecture to backends, down to embedded. Security-first, automation-driven. I bring your MVP to production.

Hi,

I'm a Berlin-based software engineer working both locally and remotely. During my PhD I built strong big-data analytics experience with TensorFlow and Keras, analysing large datasets with high precision and speed.

In 2018, I co-founded seismiq GmbH and lead the development of a new sensor system for earthquake preparedness, combining edge computing and AI.

Python was my primary language for over a decade before I moved to Rust about six years ago. Since then I've built deep expertise across the ecosystem — tokio, serde, thiserror, tracing, tauri, chrono, and more — and developed embedded Rust applications for ARM Cortex, ESP32, and RP2040. Working that close to the metal sharpened my grasp of Rust's core strengths: borrowing, lifetimes, and writing efficient code for highly resource-constrained hardware.

I care about clean, maintainable code, treat security as a first-class concern, and automate as much of the development lifecycle as I can. I also bring strong DevOps experience. Since the rise of LLMs, I use Claude Code to work faster while my experience lets me steer architecture and make sound design decisions.

I'd love to chat. Let's get in touch.

Projekthistorie

Software Architect Rust / Python and Managing Director

Seismiq GmbH

Architektur und Bauwesen

< 10 Mitarbeiter

As engineering lead, I drove the design, implementation, and testing of an extensible sensor platform spanning both hardware and software — including a scalable Rust/Python backend and a web frontend. From the outset I established a high level of CI/CD automation and infrastructure as code (Ansible), which paved the way for very short development and release cycles.
  1. Embedded Linux & embedded Rust for IoT devices (Yocto)
  2. Extensive deployment automation with GitLab CI, Ansible & Docker
  3. Full-stack development across Rust, Python, and Vue.js
  4. Infrastructure monitoring with Grafana & InfluxDB

Senior Software Engineer

Nala Earth GmbH

Energie, Wasser und Umwelt

< 10 Mitarbeiter

  1. Rust backend development
  2. Svelte frontend
  3. AWS infrastructure extension and maintenance

Senior Software Engineer Rust

OsTech GmbH

Industrie und Maschinenbau

10-50 Mitarbeiter

I developed a rust backend and desktop application using tauri and
svelte for efficient, user-friendly testing of laser controllers. The chosen
combination of tauri and svelte allowed to deliver a fully functional UI
with blazing fast backend that asynchronously (tokio) manages large
laser arrays and analyses recorded data.
  • Tokio async runtime
  • Postgresql for persistance
  • Sea-Orm for database handling (postgres)
  • Svelte + tailwindcss (UI)

Software & DevOps Engineer

Baker Hughes

Energie, Wasser und Umwelt

>10.000 Mitarbeiter


I automated deployments of legacy software towards continuous delivery.
Review of the softare stack, deployment and testing strategy in place to
analyze and improve deployment processes. I optimized existing software
for efficient containerized orchestration (Azure DevOps & Kubernetes).
I developed an OpcUa client in rust to bootstrap existing services in a
kubernetes cluster.
  • GitOps w. ArgoCD shipping with k8s
  • Containerization of existing software
  • OpcUA client and server using rust
  • C# interface for Podman to manage container
  • Design and implementation of integration tests
  • Hosting trainings on containerization and DevOps principles

Scientific Software Engineer

German Research Centre for Geosciences GFZ Potsdam

Architektur und Bauwesen

1000-5000 Mitarbeiter

I designed and implemented Python tools around the open building map that analyse building footprints and ground motion predictions. OpenAPI web service and front-end for user accessibility. I trained deep convolutional neural networks for the detection and localization of massive earthquake swarms. I leveraged distributed computing in Python for geospatial big data (PostGIS).
I co-developed a seismological data processing framework (pyrocko.org) which has become a standard in the seismological global community.
