Digital Space Agency

Services: Flutter development, AI automation and technical leadership

One senior engineer, accountable end to end. Based in Hamburg and working remotely with UK and EU teams on CET.

Flutter and mobile app development

I design, build and release cross-platform apps in Flutter and Dart, and native apps in Swift and Kotlin where it makes sense. Typical work: new product builds, feature squads inside an existing team, performance and crash fixes, and store submission and release pipelines.

  • Flutter, Dart, Provider, Riverpod, GoRouter
  • iOS (Swift) and Android (Kotlin)
  • Firebase, REST APIs, RevenueCat subscriptions
  • Unit, widget and integration testing; GitHub Actions and Xcode Cloud CI/CD

AI agents and n8n automation

I build n8n workflows and MCP-based AI agents that run reliably: schema-validated tool calls, retries, error handling and monitoring. Good for back-office processes, content and data pipelines, and internal tools.

Technical leadership and audits

Fifteen years of shipping production apps. I can lead a mobile team, review an app's architecture and release process, or take over a struggling codebase and stabilise it.

Engagement

Contract and freelance (day rate, on-site or hybrid in Hamburg, or remote) and open to full-time roles. Get in touch with scope and timing.

FAQ

Do you work on contract or as a full-time employee?

Both. I take freelance and contract engagements (on-site or hybrid in Hamburg, remote for UK and EU teams on CET) and I am open to the right full-time role.

What do you build?

Production mobile apps in Flutter, plus native iOS (Swift) and Android (Kotlin) when the project needs it, and AI agent and n8n automation workflows.

Who will actually do the work?

Me, David Miller. Digital Space Agency is a one-person studio. I use AI agents and n8n automations for back-office work and for speeding up engineering, with every release reviewed and tested by me.

Which time zones and languages do you work in?

Central European Time, in English. I work with teams across the UK and EU.
