About Me

I'm a Senior Full Stack Engineer with 16+ years of experience building scalable web platforms and SaaS products. I specialize in the modern JavaScript ecosystem including TypeScript, React, Next.js, and PostgreSQL.

I design and build systems end-to-end, from frontend architecture and complex user interfaces to APIs, databases, and infrastructure. Much of my work focuses on turning complex or evolving product ideas into reliable, maintainable software.

I'm often brought into projects to untangle architecture, stabilize systems, and ship features that move products forward. I enjoy working close to product teams and translating real business needs into clean technical solutions.

As an autism advocate, I value diverse ways of thinking and bring a unique perspective to problem solving, system design, and team dynamics.

Common questions about working with me

I take an end-to-end approach to building systems, from frontend architecture and complex user interfaces to APIs, databases, and infrastructure. I focus on turning complex or evolving product ideas into reliable, maintainable software. I'm often brought into projects to untangle architecture, stabilize systems, and ship features that move products forward.
My core stack includes TypeScript, React, Next.js, Node.js, PostgreSQL, and GraphQL. I'm also experienced with Nest.js, Prisma, Docker, and various headless CMS platforms like Payload CMS and Strapi. I'm technology-agnostic and always choose the right tool for the job.
I'm based in Berlin, Germany and open to both remote and on-site opportunities. I'm also willing to relocate for the right opportunity. I've successfully worked with clients across different time zones and locations.
I specialize in both! I love greenfield projects, but I'm also experienced in rescue engineering: untangling messy codebases, stabilizing systems, and improving existing architectures. I can help refactor legacy code, implement modern patterns, and mentor your team.
Yes! I have extensive experience conducting training sessions and workshops. At Sevenval, I organized and led workshops on Responsive Design, Mobile First, and Frontend Architecture. I also provide coaching to team members and have conducted technical interviews and recruitment.
I've worked across multiple sectors including banking (Postbank, Volksbank, Liechtensteinische Landesbank), insurance (Swiss Life), pharma/healthcare (Bayer), legal tech (Rechtsanwalt.com, Jurono), e-commerce (PreisHoheit, Planted), and real-time video streaming (Nanocosmos).
I'm currently open to both freelance projects and full-time opportunities. With 16+ years of experience and a track record of 25+ freelance projects with 60% repeat clients, I bring reliability and expertise to every engagement.
I believe in clear, transparent communication. I share context, trade-offs, and technical reasoning to help teams make better decisions. I'm experienced with Agile/Scrum methodologies and PMP project management approaches.
