Senior engineering, the way good teams want it

Whether you need a platform architected, a frontend made fast, or a stalled project rescued — here's how I can help, and how we'd work together.

Headless platform architecture

Design and build content platforms that decouple a robust backend from a fast, modern frontend — so editors stay productive and developers stay sane.

  • Future-proof headless setups (TYPO3, Strapi, Payload) with clean content contracts
  • Reusable component libraries shared across client projects
  • Architecture your team can extend without calling me every week

Enterprise CMS engineering

Deep TYPO3 and CMS work — migrations, content blocks, integrations and editor experience for organisations that live in their CMS.

  • Complex TYPO3 13 builds and version migrations done right
  • Custom content blocks and data processing tailored to editors
  • Integrations with PIM, DAM, search and third-party APIs

Modern frontend engineering

Production frontends in Nuxt, Svelte, Vue and React that are fast, accessible and a pleasure to maintain.

  • Core Web Vitals in the green, measurably
  • Accessible, responsive UI that converts
  • Design systems and component libraries built to scale

APIs & systems integration

Backend services and integrations in PHP and Node.js that connect your stack and hold up under load.

  • Well-documented REST APIs and clean data models
  • Third-party integrations that fail gracefully
  • Background jobs, webhooks and automation that just work

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.

  • Clear written audit: what is solid, what is debt, what is on fire
  • Prioritised, costed remediation plan
  • Hands-on stabilisation so releases stop being scary

Cloud & delivery

Reliable delivery pipelines and AWS infrastructure so your team ships small, ships often and sleeps at night.

  • CI/CD with GitHub Actions and reproducible Docker builds
  • AWS infrastructure sized to your actual needs
  • Observability so you find problems before users do

Engagements

Three ways to work together

Every engagement starts with a conversation and a written plan. Pick the shape that fits your situation.

Fixed-scope project

A defined build with a clear goal

We scope the work, agree a price and timeline, and I deliver. Best when the outcome is well understood.

  • Written scope & milestones
  • Fixed price, no surprises
  • Handover & documentation included
Most popular

Embedded / fractional

Teams that need senior firepower

I join your team for a set number of days per week — reviewing, building and levelling up the codebase alongside your people.

  • Senior pair for your team
  • Code review & mentoring
  • Flexible weekly commitment

Audit & advisory

Decisions before you commit budget

A focused engagement to assess a codebase, de-risk a decision or plan an architecture — delivered as a written report you can act on.

  • Technical audit & risk map
  • Architecture recommendations
  • Costed, prioritised roadmap

Project engagements typically start around €5,000. Not sure if yours is a fit? Just ask — I’ll give you an honest answer.

TYPO3 Health & Upgrade Audit

A fixed-scope assessment of your TYPO3 platform — security, upgrade-readiness, performance and technical debt — delivered as a clear, prioritised report you can act on.

  • Full review of your TYPO3 codebase, extensions and configuration
  • Security & upgrade-readiness assessment (your version → current LTS)
  • Performance and technical-debt findings, prioritised by risk
  • A written report with a costed, prioritised action plan
  • A walkthrough call to talk through the findings and next steps

How it works

A calm, predictable process

No mystery, no scope creep, no lock-in. Here's the path from first message to handover.

01

Intro call

A free 30-minute call to understand the goal, constraints and timeline — and whether I'm the right fit.

02

Scope & plan

A written scope, estimate and milestones. You know the plan and the cost before any work begins.

03

Build & ship

Focused, transparent delivery with regular check-ins. Small, frequent releases over big-bang surprises.

04

Handover

Documentation, knowledge transfer and a codebase your team can own — not one that depends on me forever.

FAQ

Good questions, answered

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.
