Full-stack and AI engineer with a production-minded approach.
More than five years of professional experience across PHP, Symfony, JavaScript/TypeScript, TYPO3, PrestaShop, APIs, and modern operations. Applied AI, LLM integration, and intelligent automation extend this full-stack profile.
How I build intelligent systems.
I combine clean backend architecture, clear APIs, and accessible interfaces with AI capabilities that perform traceable tasks. What matters is not only a model response, but also data quality, validation, performance, security, and controllable operations.
I currently work full-time as a Full-Stack Developer at SJmedia GmbH.
Where I have worked.
Full-Stack Developer
- Develop scalable websites, web applications, and online shops with PHP (Symfony/Laravel), JavaScript/TypeScript, React.js, and relational databases.
- Design REST APIs, third-party integrations, and data-driven automation workflows.
- Build production-oriented AI capabilities for e-commerce, including data-based business insights and controlled product-content/SEO workflows.
- Design and implement a suite of six company-owned PrestaShop modules and a TYPO3 extension with Graph API integration, caching, and fallbacks.
- Contribute to deployment and infrastructure with Docker, Linux, Apache, and Nginx; use AI development tools for analysis, implementation, and documentation.
Full-Stack Developer
- Led development of scalable web applications with PHP (Laravel, Symfony) and Node.js.
- Contributed to system architecture, DevOps, and CI/CD using Docker, Kubernetes, and GitLab.
- Rebuilt the high-traffic KulturRegion Stuttgart platform - 40% faster loads via MySQL indexing and API optimization.
- Built Audit Factory with Symfony and React - 30% performance improvement through caching and robust REST APIs.
- Unified 67 partner sites for the Locatec relaunch - 60% less maintenance effort and 3x faster updates.
- Delivered UIs for 12+ websites and scalable PHP/Node.js backends over 27 months.
Working Student - Development

Principles I build by.
Performance first
Speed is not a finishing touch - it is a design constraint. I optimize databases, queries, and front-end builds so pages load quickly and stay there.
Clean architecture
Maintainable code and clear structure beat clever shortcuts. I build systems that the next developer can understand and extend.
Clear communication
Transparent progress, honest expectations, and no jargon. I keep people in the loop so technical work stays understandable.
Reliable delivery
Automated tests and CI/CD pipelines mean releases are predictable and reversible - fewer surprises, more uptime.
Measurable results
I care about outcomes that matter in practice: faster loads, clearer workflows, less maintenance, and systems that are easier to improve.
Built to last
Security, accessibility, and upgrade-safe patterns from day one - so the work holds up long after launch.
Always learning, always building.
Outside of day-to-day development work, I follow new technologies, tools, and frameworks closely and contribute to open-source projects. Staying hands-on with the wider ecosystem is how I keep my craft sharp and bring fresh ideas back to the work.
I am also exploring how AI-assisted development fits into a real full-stack workflow - using it to ship faster while keeping quality and understanding firmly in human hands.
