Focus

What I specialize in

From the Flutter front end to Terraform-managed cloud infrastructure — these are the areas where I add the most value.

Mobile Development with Flutter

Cross-platform iOS and Android apps from a single codebase — from architecture to release in the App Store and Play Store.

Fullstack Engineering

REST APIs and backend services with Python (FastAPI, Flask), wired up to modern Flutter front ends — from architecture to delivery.

Data Modeling & Persistence

Structured data models in PostgreSQL, versioned and migrated with Alembic — a reliable foundation for backend services and analytics.

Cloud Run & Google Cloud

Microservices running as containers on Google Cloud Run, including IAM, networking and deployment configuration across multiple environments.

Infrastructure as Code

GCP infrastructure — projects, networks, CI/CD runners — made reproducible and version-controlled with Terraform instead of manual console clicks.

DevOps & CI/CD

Automated build, test and deployment pipelines with GitLab CI, Docker and Fastlane — from commit to production.

I am a Senior Software Engineer with a Master's degree in Computer Science and more than six years of professional experience building mobile applications, backend services and cloud-based systems. My focus is on Flutter, Python and Google Cloud, complemented by modern DevOps and Infrastructure-as-Code practices.

I don't just write application code. I design, build and operate complete software systems.

Fullstack & Mobile Developer

Schwäbisch Media – Das Medienhaus im Süden

Mobile · Backend · Cloud · DevOps

Since June 2024 I've owned fullstack and mobile development for iOS and Android within the app team. I build and extend Flutter apps, design new features, and build backend services with FastAPI and Flask that I run as microservices on Google Cloud Run. I manage the underlying GCP infrastructure — networks, projects and CI/CD runners — as Terraform-based Infrastructure as Code. I also take technical responsibility for our production applications and advise product owners, concept designers and graphic designers on technical questions.

Web Development · Backend

During this time I was responsible for maintaining and developing a web application for the graphical evaluation of engine test bench utilization, used by internal managers and team leads. The web app was responsive and hosted on an internal Windows server. The backend used the Python framework Django for business logic and as a connection interface to an Oracle database for reading measurement data.
