You will get Fix your broken Claude or OpenAI API integration in Next.js
Project details
Built an AI feature that's broken in production? Rate limiting, token overflow, broken streaming, or responses that stop mid-generation — these are all solvable and I've debugged all of them building my own AI-powered platforms.
What I fix:
• Rate limit errors and missing retry logic
• Prompt length exceeding context window limits
• Streaming responses breaking in Next.js App Router
• API key scoping and environment variable issues
• Response parsing failures and malformed outputs
I work with Claude, OpenAI, and other LLM providers. Same day for most issues. You get a working integration, error handling added, and clear notes on what broke and why.

Frequently asked questions
About Curtis
Full-Stack Developer Fixing Next.js MongoDB and AI Integration Issues
Oulu, Finland - 1:03 pm local time
I'm a full-stack developer specialising in Next.js, MongoDB, Coolify deployments, and LLM/AI integrations. I've personally hit and solved most of the production errors that eat founders' time: MongoDB Atlas connection failures, Next.js builds that work locally but break on Coolify, Claude and OpenAI integrations throwing rate limit or context errors, and pages that Google simply won't index.
I fix these fast. Most issues resolved same day.
Beyond debugging, I build full-stack applications for startups — from MVP to production. I currently run FounderVouch, an event matchmaking platform for Nordic startup ecosystems, so I understand what founders actually need: working software, clear communication, no hand-holding required.
8 years in the British Army taught me one thing that transfers directly to client work: you deliver what you said you'd deliver, when you said you'd deliver it. No excuses.
What I work on:
• Next.js application development and debugging
• MongoDB Atlas configuration and connection issues
• Coolify and VPS deployment troubleshooting
• Claude / OpenAI / LLM API integration and error handling
• SEO technical fixes — indexing, robots.txt, Search Console setup
I work with: Startup founders, product teams, and developers who are stuck and need a fast, experienced pair of hands.
Available for same-day fixes, short sprints, and ongoing technical support.
