I design, build and take ownership of web platforms, integrations and the cloud infrastructure underneath them — from system architecture to zero-downtime deployment. For companies where reliability isn't a feature, it's the foundation.
Available for 1–2 engagements · Remote, worldwide — based in Germany (CET/CEST)
What I do
Most of my work clusters around systems integration and platform architecture — plus the cloud infrastructure underneath and the frontends on top.
I connect the systems that have to talk to each other: ERP, shop, CRM, content platform. REST APIs and backend services in Node.js and PHP that hold up under load — including automating the manual processes that cost your team hours every day.
Architecture decisions that hold for five years: decoupling backend from frontend, data models, scaling paths. I design platforms so editors stay productive, developers enjoy working on them — and a relaunch never becomes a rebuild.
Zero-downtime deployments, multi-instance setups, CI/CD with GitHub Actions. I have run production AWS infrastructure on my own responsibility for years — not just set it up.
Inherited a stalled or fragile project? I analyse the codebase, name the real risks and deliver a pragmatic path back to shipping — as a fixed-price audit with a written report.
Deep TYPO3 expertise for organisations that live in their CMS: migrations (currently up to v13), integrations, security advisory, editor experience. TYPO3 CMS Certified Developer.
Production frontends in Nuxt, Vue and React — fast, accessible, maintainable. The frontend is what your users actually feel.
Selected work
A few engagements that show how I work. Real numbers, real constraints.
Six years of architectural and operational ownership of a mortgage broker’s platform: TYPO3 + Vue, automated lead routing to the right branch, an embeddable financing calculator on partner sites — on an AWS multi-instance infrastructure I administered myself. Zero-downtime deployments, for six years.
The architectural call: an automation layer between supplier data and storefront (Strapi + Nuxt 3). The result: catalog maintenance down from days to about an hour, with thousands of products syncing themselves.
A React extension in the Learn panel of a leading creative suite — shipped across several apps in the suite, plus a reusable MJML email library. Enterprise-grade stability and review requirements included.
Ongoing platform ownership and security advisory for a manufacturer of refractory materials: maintenance, further development and an update/hardening strategy — also as advisor to the partner agency.

FAQ
Kim Martini is a software architect with 12+ years of experience. He designs and takes ownership of web platforms, systems integrations and the cloud infrastructure behind them — interfaces (REST APIs, Node.js, PHP), AWS operations and enterprise content platforms (TYPO3, TCCD-certified). Remote from Germany, in German and English.
Ambitious platform work: systems integration and interfaces, architectural ownership of web platforms, complex TYPO3 projects, performance-critical frontends — and rescuing stalled projects. Engagements typically run 2–3 days per week over several months, or as a fixed-price project.
Three ways: fixed-scope projects with a written scope and fixed price; embedded/fractional work where Kim joins your team, typically 2–3 days per week over several months; and audit/advisory engagements delivered as an actionable written report. Every engagement starts with a short call to confirm fit.
Yes. Kim works remotely from Germany (Central European Time) with clients worldwide, and is available on site in the DACH region. Communication is in German (native) or English (fluent), with overlap maintained for European and many North American working hours.
Systems integration and platform architecture. On the backend that means REST APIs, Node.js and PHP; in the cloud, AWS, Docker and CI/CD with GitHub Actions; for content platforms, TYPO3 up to v13 plus Strapi and Payload; on the frontend, Nuxt, Vue, React and TypeScript. Kim is a TYPO3 CMS Certified Developer (TCCD).
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.
Tell me the goal and the constraints. You'll get an honest read on whether I'm the right fit, and a clear plan if I am — no pressure, no sales script.
