From Zero to Product.
Senior Fullstack Engineer & Solution Architect — delivering across hardware, cloud, and AI systems for 12+ years.
My services
My approach: Pragmatic. Tech-agnostic. Sustainable.
1. Greenfield: Building Foundations
Startups and established companies need speed — but not a technical debt trap. I build no "one-shots" that fall apart after launch.
- Architecture for the long run: I design systems that scale from MVP to enterprise level.
- Tech stack with foresight: I choose technologies that still make sense tomorrow (e.g. Astro, Supabase, AWS).
2. Brownfield: Renovation & Modernization
I bring light into black-box architectures and ensure hard-to-maintain legacy systems become efficient and controllable again.
- Legacy Rescue: I stabilize shaky systems, refactor code in production, and make "black boxes" transparent again.
- Migration: I bring monolithic applications to the cloud or modularize them — without downtime.
3. System Integration & Automation
When systems don't talk to each other, I build the bridge.
- API Orchestration: I connect disparate interfaces into a working unit.
- Data Retrieval: I extract data even from "locked" systems and make it usable for your processes.
4. The Bridge: Edge, Kiosk & Cloud
The world doesn't end in the browser. I connect software to the physical world.
- Hardware Integration: Whether kiosk systems, terminals, or IoT devices — I integrate seamlessly into existing hardware.
- Hybrid: Moving logic to the device (edge computing with C++/Rust) while maintaining cloud connectivity.
AI Competencies: Tool & Building Block
I use Artificial Intelligence in two dimensions: as a developer who integrates it, and as a power user who directs it.
A) AI Engineering: I build AI for you
I integrate LLMs and AI services directly into your products. Whether a chatbot that knows your company's knowledge (RAG), or complex processes to be automated by AI agents — I implement these technologies securely, privacy-compliantly, and scalably (e.g. via AWS Bedrock).
- Integration: AWS Bedrock, OpenAI, or local models into your business logic.
- RAG & Automation: Systems that make your company data intelligently retrievable.
B) Context Engineering: I work with AI
I use AI to boost my productivity.
- Efficiency: Through precise context engineering I analyze complex legacy codebases in record time.
- High-Speed Output: Faster creation of boilerplate, tests, and documentation — leaving more time for architecture and logic.
- Mentoring: I train your team in safe and productive use of copilots and LLMs.
My Toolbox
I don't define myself by a language, but by the solution.

Work Style & Flexibility
I work primarily remote, but I'm there when it counts. For kick-offs, critical workshops, or team onboarding, I naturally come to you on-site. Personal contact builds trust and accelerates processes.
Why hire me?
My quality promise:
- I leave behind clean code.
- I write understandable documentation.
- I empower your team to continue independently.
When I leave the project, your system runs more stably, and your team is up to date with the latest technology. You're not booking a dependency, but sustainable progress.
I'd love to talk with you about your current challenges. Let's find out together how I can support you.
