Services

From writing individual software to owning the product end to end: I take accountability for roadmap, backlog and architecture.

Technical Product Ownership

Interim / Fractional Product Owner · Discovery to Release

Product ownership backed by architectural judgment: I align product vision, stakeholder goals and technical feasibility into a clear roadmap and actionable backlog — steering the team from discovery to production releases.

AI Product Strategy & LLM Integration

AI Product Owner · From PoC to Production

From AI prototype to reliable product capability: I evaluate AI use cases for real business impact, scope document and data pipelines, and guide integration into daily workflows instead of isolated demos.

Solution Architecture & Modernization

Solution Architect · Target State, ADRs & Migration

Decouple legacy monoliths without downtime, define clean event-driven boundaries (Kafka, CQRS) and record decisions as ADRs — so product roadmap and system architecture move at the same pace again.

Cloud Platform & Delivery Governance

Platform Lead · GCP, Kubernetes & Operations

Reproducible delivery pipelines, Kubernetes on GCP, observability, disaster recovery and cost governance — a platform foundation that lets product teams ship safely and fast.

Case studies

Products I designed and built end to end.

Auftrag One

Senior software architect · 2022 – present

Auftrag One

Challenge: Relevant public tenders are spread across 200+ German, Austrian and EU sources, and companies miss them.
What I built: An event-driven platform on Go, Rust and Kafka that ingests every notice, classifies it into 331 topics with Gemini AI and scores it against each company profile. Runs on GKE with CI/CD, auto-scaling and automated backups.
Result: 530k+ notices analysed, ~8.5k new every week, 500+ active users.

Artconnect

Software architect · 2020 – 2022

Built pre-AI

Artconnect

Challenge: A legacy Ruby on Rails monolith limited how fast the platform could grow and ship.
What I built: A Kotlin/Spring Boot service architecture following CQRS, Kafka messaging, Elasticsearch full-text search, Helm deployments on Kubernetes and a rebuilt Next.js frontend.
Result: Monolith split into 6 independent services with zero downtime, handling 100k+ requests per month.

OnSand

Own product · 2025 – present

Challenge: Beach volleyball games get organized in scattered group chats, and clubs manage members in spreadsheets.
What I built: A Flutter app for finding games and skill-rated partners, plus a Next.js workspace for clubs — both on Go and Rust services with PostgreSQL and Meilisearch search, running on GKE.
Result: Two live products: the OnSand player app and OnSand Cloud for clubs, which processes club data in the EU only.
