I will integrate claude or gpt ai into your app, website or workflow
Justus T.
About this gig
I add real AI features to your app, website or workflow using Claude or GPT, built properly so they run in production, not just in a demo.
I'm the founder and engineer of Arcamatrix (arcamatrix.com), a production AI platform I built and run solo. You get that same engineering.
What I can build in:
Summarize and extract from documents, emails, tickets or calls
Classify and route: tag, prioritize, auto-assign
Draft and reply in your tone, on brand
Chat over your own data (grounded answers, not guesses)
Connect your tools: APIs, webhooks, databases
How it works: (1) we scope the feature and where it plugs in, 15 min. (2) I build, test and add error handling. (3) you get it integrated, documented and explained, ready to run.
Why me:
I build and operate real AI systems, not demos
Reliable by design: error handling, rate limits, cost control
Clear docs and a walkthrough so your team can run it
Fast delivery with modern AI tooling
Have an idea but not sure how? Message me first, I'll scope it honestly before you order.

Languages
German, English
I build AI systems that do real work: workflow automations (n8n, Make, Zapier), AI chatbots grounded in your own documents, and Claude/GPT integrations. I develop with Claude daily and ship working prototypes in days, not weeks. Typical projects: lead-qualification pipelines, support bots, document and invoice extraction, missed-lead follow-up, and custom AI tools or web apps. Native German speaker (bots that sound right), GDPR-compliant EU hosting. Founder of Arcamatrix (arcamatrix.com), a production AI video platform built end to end. Message me before ordering and I'll confirm scope.
FAQ
Do I need my own OpenAI or Anthropic API key?
For ongoing use, yes - so usage bills to you (I guide you through setup). I build and test on my side first, then hand it over.
Can you work with my existing app or codebase?
Usually yes. Share the repo or your stack and I'll tell you exactly how the AI feature plugs in before you order.
What exactly do you deliver?
Working, integrated code plus a short doc and a walkthrough - so you and your team can run and adjust the AI feature yourselves.
