I build what you are missing.

I build websites, apps and integrations for ambitious companies. From the first sketch to live and running, no compromises.

Clients I have worked with

What I build

Four things. I’m good at all four.

Websites and landing pages

WordPress or custom React. Sites that convert and load fast. No 3-month agency projects.

  • WordPress or headless React
  • Fast delivery: 2-4 weeks
  • Performance + SEO from the start
  • Custom design, not templates

Shopify and WooCommerce

Webshops built to sell. Custom themes, speed optimisation, and automations that save you time.

  • Custom Shopify themes
  • WooCommerce setup
  • Apps and integrations
  • Checkout optimisation

App development

iOS and Android from one codebase — Flutter or Ionic/Vue. Apps that work, from MVP to App Store in weeks, not years.

  • iOS + Android at the same time
  • API and hardware integrations
  • Fast MVP
  • Submission to the App Store

APIs, integrations and AI

When your systems need to talk to each other. From Shopify↔Dinero syncs that give you real-time spend visibility, to AI agents that work with your own data.

  • REST and GraphQL
  • Dinero, Shopify, Toggl and more
  • AI agents and RAG
  • Webhooks and background jobs

I also do

Workshops

I plan and run workshops where your users try your product and tell you what works and what does not.

  • Agenda, props and participants
  • Structured feedback on form, function and use
  • Wrap-up with a prioritised list

Focus group studies

A small group, open questions and someone who writes it down afterwards. You learn why, not just what.

  • Recruiting and moderating
  • Notes, themes and report
  • In person or hybrid
Read more →
IoT and hardware

Sensors, MQTT, ESP32 and micro:bit. For when something needs measuring, controlling or automating in the physical world.

  • ESP32, M5Stack, micro:bit
  • MQTT and real-time data
  • Dashboards and monitoring
  • From prototype to production
Dashboards and internal tools

Quote generators, invoicing systems, planning tools, scanner sync. Custom tools that replace the Excel hell.

  • PDF generation
  • Live dashboards
  • FastAPI and PocketBase
  • Multi-tenant if needed

CTO Service

How we work

No black box. You know what’s happening and when.

  1. 01

    Chat (30 min)

    No strings attached. You tell me what you need, I tell you what I'd do. If we both think it makes sense, we go from there.

  2. 02

    Estimate and scope

    You get a written quote with a fixed price, delivery time and what's included. No surprises later.

  3. 03

    Build in sprints

    Design and development in 1-2 week sprints. You see progress as it happens. No 'we'll be done in 6 months, promise'.

  4. 04

    Launch with tracking

    Live with analytics, Core Web Vitals checked, monitoring set up. Not 'live and forgotten'.

  5. 05

    Support and iterate

    30 days of support is included. After that, a punch card if you need ongoing help. No lock-in.

Tech stacks I work in

Working in the same stack? We can help each other.

React + Payload

React frontend, Payload CMS and backend. My primary stack for websites and webshops.

See it in practice:

FastAPI + PocketBase

Lightweight backend combo for apps and internal tools. FastAPI for logic and API, PocketBase for data and auth.

WordPress

Custom WordPress themes when it's the right tool for the job. Clean code, not page-builder spaghetti.

Medusa + Payload + React

E-commerce stack: Medusa drives commerce, Payload drives content, React ties it together.

Ionic + Vue

One codebase, several platforms. For app projects that need to hit iOS, Android, and web.

Flutter

When the app needs to feel fully native. One language, Dart, same result on iOS and Android.
