Über diesen Service

I fix, upgrade, and extend existing Ruby on Rails apps from a single bug fix to building a new feature or MVP on top of what you already have.


What I do:

  • Fix bugs, errors, and things that stopped working
  • Build new features into an app you already have
  • Turn your idea into a working product you can launch
  • AI features: see my AI integration gig
  • Connect your app to Stripe, payment providers, or other services
  • Make slow apps faster and fix things that break under load
  • Upgrade older apps so they stay secure and maintainable
  • Review a codebase you inherited and explain what you actually have


Stack: Ruby on Rails, React, GraphQL, PostgreSQL, Redis, AWS, Heroku, Docker, plus OpenAI, Claude, and Gemini APIs for AI features.


Seven years working on production applications with live users, including five published to a public app store. I work on existing codebases, including ones I did not write.


Not sure how big the job is, or whether it is even possible? Message me and describe it in plain words. I will tell you honestly what it involves and what it should cost before you order anything.

Ruby on Rails developer, 7 years in production. I build and fix Rails and React apps, APIs, and the things that break under load. I add AI that actually does something: chatbots trained on your data, assistants that take actions, Claude or ChatGPT wired into your app. Current focus is agentic commerce, making stores discoverable and shoppable by AI agents. 5 of those years were in Shopify and BigCommerce: 5 apps shipped to the Shopify App Store, plus Functions, checkout extensions, and API integrations. Tell me what you need in plain words and I'll tell you what it takes and costs.
