BUILDING SCALABLE SOFTWARE, CLOUD PLATFORMS AND AI-POWERED PRODUCTS

Good software is a business decision.

I build and own systems that revenue depends on — from cloud architecture to AI integration. For 15 years, for corporations like BMW, TUI and Rossmann as well as for startups.

01 — RESULTS

What you can measure me by.

No buzzwords — systems that run today, delivering the result they were built for.

100,000+
price updates per day
Cache system for pricing & availability

High-load cache for travel prices and availabilities, designed and shipped to production. Running in regular operation for years — without nightly heroics.

OCR sender recognition for letter pre-notification

Computer-vision pipeline for automatic sender recognition — integrated production-ready into one of Germany’s largest logistics processes.

Own product studio — from idea to operations

As co-founder and CEO/CTO of LaunchX GmbH I own UptimeEye, PlannyMeals, BrutalCoach, LaunchPilot, Miroir and TrackyMeals end-to-end: a shared OpenAPI-first Go backbone, deep LLM integration, a fully agentic development workflow.

02 — SERVICES

What I take on.

Four disciplines — in each of them I have taken my own systems into production, and operated them beyond that.

01

Cloud-native architecture

Production-ready platforms on Kubernetes & AWS — architecture that uses the cloud instead of merely renting it.

AWS EKS · TERRAFORM · FLUXCD · GITLAB CI
02

Backend engineering

Java & Go for systems that digest millions of events per day. Event-driven, cleanly cut, operable.

JAVA · KOTLIN · GO · SPRING BOOT · KAFKA · POSTGRESQL
03

Frontend where it counts

React & Next.js when the backend needs a face — still readable two years from now.

REACT 19 · NEXT.JS 15 · TYPESCRIPT · TAILWIND
04

AI integration

Agentic workflows, OCR & LLM pipelines — pragmatically in production, with predictable costs and clear failure modes.

03 — APPROACH

Four sentences I measure every decision against.

I
Business impact before technical elegance.

Elegant code solving the wrong problem is waste. First understand what matters — then build.

II
Operability is a feature.

A system that can’t be debugged at 3 a.m. isn’t finished. Logs, metrics, traces belong in the design.

III
Boring tech, where possible.

Postgres before Mongo, Kafka before the latest trend. Proven tools beat GitHub hype every time.

IV
Code someone can delete.

Modules with clear boundaries, no needless lock-in. Software that outlives the next generation.
