Thoughtful interfaces. Resilient systems. I connect the details to the bigger picture — and take care of everything in between.
01 / Selected work
Public infrastructure, ambitious startups, and everything in between. A selection of the platforms I’ve helped bring to life.
Making a complex public system clearer, more accessible, and ready for its next chapter.
Modernising “Haushaltsvollzug”, the platform used to plan and execute the German federal budget: domain-driven microservices in Java (Spring Boot) and Go, clear API contracts and WCAG-compliant React frontends.
Connecting language models with the knowledge and workflows that make them useful.
Retrieval-augmented chatbots and a shared LLM API built on pgvector, Pinecone, OpenAI and LangChain, integrated into a multi-tenant CRM.
Giving multiple organisations a shared foundation without giving up their independence.
Terraform infrastructure across AWS and Google Cloud for several organisations, plus a customisable CRM with a tested shared component library.
Bringing clarity and responsiveness to a trading experience where every interaction counts.
Dynamic, responsive React components for a cryptocurrency exchange, and account verification flows that improved security and onboarding.
Helping developers find their next team — and building a platform for sharing what they know.
Built the matching platform with React and Node.js, led the backend of a video-streaming service for developers and ran production on Google Cloud with Kubernetes.
Building the trust layer that connects people, accounts, and services.
Designed and implemented an in-house OAuth2 identity provider together with the RESTful APIs around it.
BASED IN02 / About
Hi, I’m Kevin. For over twelve years, I’ve been building software people can depend on — from the first interaction to the infrastructure behind it.
I work closely with your team, ask the right questions, and take ownership across the stack. I care as much about sharing knowledge and working well together as I do about the code.
Tests, reviews and releases that are boringly predictable.
Fast by default, measured rather than guessed.
WCAG 2 is the floor, not a feature.
Teams get better when knowledge moves freely.
03 / Experience
I started with an apprenticeship at Engel & Völkers in Hamburg. Product teams taught me to see the whole system. Since 2022, I’ve brought that perspective to my work as an independent engineer.
