You will get I will diagnose and fix your MongoDB connection issues fast
Project details
Stuck on a MongoDB connection error? I've solved this exact problem dozens of times — most commonly misconfigured IP allowlists in Atlas, broken connection strings in production, and auth failures between your app and cluster.
What I fix:
• MongoDB Atlas IP allowlist blocking your app server
• Connection string errors in Next.js, Node.js, or Express apps
• Environment variable mismatches between local and production
• Replica set and timeout configuration issues
I'm a full-stack developer and active startup founder running a live Next.js and MongoDB platform in production. I've hit these errors myself and know exactly where to look.
Most issues resolved same day. You get the fix, a clear explanation of what caused it, and how to prevent it happening again.

About Curtis
Full-Stack Developer Fixing Next.js MongoDB and AI Integration Issues
Oulu, Finland - 12:14 am 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.
