Where I Add Value
Modern engineering teams hit these problems. Here's where my experience makes a difference.
Production Systems with Hidden Architectural Debt
Legacy monoliths that resist scaling. Microservices coupled in all the wrong ways. Cloud migrations that stall mid-flight. I've led the transition from legacy to event-driven architectures at Germany's 3rd-largest media platform (Ippen Digital) and modernized core banking systems at Atruvia.
AI Integration That Needs to Survive Production
LLM-powered features built as prototypes that don't hold up in production. I bring the architectural discipline that makes AI maintainable, observable, and cost-efficient at scale: thoughtful prompt design, LLM-as-component patterns, and OpenAI/Gemini/Claude API integration that survives load and review.
Engineering Teams Without a Senior Tech Lead Voice
Greenfield projects without architectural rigor. Distributed teams that need mentorship and standards. Founder-led products that need a senior engineering counterpart. CTO reps from Micronest (German Accelerator) and Oncochain, plus Staff Engineer / System Owner work at Ippen Digital and architecture lead at Condat AG.
How I Can Help
What I bring to a team — full-time, fractional, or advisor.
Software Architecture & Modernization
Architectural design and review for cloud-native systems, legacy modernization, and microservices transitions. iSAQB CPSA + AWS Solutions Architect Associate. Output: written architecture review with prioritized recommendations, risk flags, and an executable roadmap.
AI Integration & Engineering
Build AI capabilities directly into your product. LLM-powered features, OpenAI/Gemini/Claude API integration, on-device inference where it makes sense, AI-augmented user flows. Designed to be maintainable and cost-efficient in production.
Technical Leadership & Mentorship
Tech Lead voice for greenfield projects, distributed teams, and founder-led products. Architecture workshops, code reviews, standards establishment, team mentorship. From CTO experience at Micronest and Oncochain plus Staff Engineer / System Owner roles at Ippen Digital.
Full-Stack Engineering
End-to-end development from architecture through deployment. Java/Spring, Python/FastAPI, React/Angular, AWS — from proof of concept to production-ready systems. AI-native features included where they belong.
About Me
Senior engineering + founder reps + AI-in-production experience.
Senior software engineer and architect based in Munich. Eleven years shipping production systems across banking (Atruvia), media at scale (Ippen Digital, Germany's 3rd-largest news network), aerospace (DLR Galileo), automotive (BMW Motorrad), and fintech (Giesecke & Devrient). The last two years going deep on AI integration: hands-on with major LLM APIs (OpenAI, Gemini, Claude), on-device LLM inference (llama.rn / Qwen), prompt engineering, and AI-augmented development workflows. Co-founder & CTO at Micronest (German Accelerator alum) and Co-founder & Lead Cloud Architect at Oncochain (healthcare data platform, ceased operations 2022). That mix is rare: real founder reps plus enterprise-scale engineering plus practical AI engineering. German citizen, fully remote OK. Currently exploring founding engineer, lead, staff, or senior architect roles in DACH or Remote-EU. Fractional and advisor engagements also welcome for the right team.
