What I do
Senior help across the whole stack
Most of my work clusters around headless content platforms and the modern frontends in front of them — but I'm at home anywhere from the database to the deploy pipeline.
Enterprise CMS engineering
Deep TYPO3 and CMS work — migrations, content blocks, integrations and editor experience for organisations that live in their CMS.
Modern frontend engineering
Production frontends in Nuxt, Svelte, Vue and React that are fast, accessible and a pleasure to maintain.
APIs & systems integration
Backend services and integrations in PHP and Node.js that connect your stack and hold up under load.
Project rescue & technical audit
Inherited a stalled or fragile project? I assess the codebase, find the real risks and give you a pragmatic path back to shipping.
Cloud & delivery
Reliable delivery pipelines and AWS infrastructure so your team ships small, ships often and sleeps at night.

FAQ
Questions clients ask first
What does Kim Martini do?
Kim Martini is a senior full-stack developer and consultant with 12+ years of experience. He designs and builds headless CMS platforms (TYPO3, Strapi, Payload), modern web frontends (Nuxt, Svelte, Vue, React) and the APIs and cloud infrastructure behind them, working remotely with teams worldwide from Germany.
What kinds of projects are the best fit?
The best fit is ambitious web platform work: headless CMS architecture, complex TYPO3 builds and migrations, performance-critical frontends, systems integration, and rescuing stalled or fragile codebases. Engagements typically run from a few focused weeks to multi-month builds.
How do you work with clients?
Three ways: fixed-scope projects with a written scope and fixed price; embedded/fractional work where Kim joins your team for a set number of days per week; and audit/advisory engagements delivered as an actionable written report. Every engagement starts with a short call to confirm fit.
Do you work remotely and with international clients?
Yes. Kim works remotely with clients worldwide and is based in Germany (Central European Time). Communication is in English or German, with overlap maintained for European and many North American working hours.
What is your technical specialisation?
Headless content platforms and modern frontends. On the backend that means TYPO3 13, PHP, Node.js and well-designed REST APIs; on the frontend, Nuxt, Svelte, Vue, React, TypeScript and Tailwind CSS; with AWS, Docker and GitHub Actions for delivery. Kim is a TYPO3 CMS Certified Developer (TCCD).
How do engagements typically start?
With a free 30-minute call to understand the goal, constraints and timeline. For build work Kim follows with a written scope and estimate; for audits, a fixed-price assessment and report. You always know the plan and the cost before work begins.
