Your Vercel project is broken or stalled. We'll fix it.
Your Vercel app builds locally. Production is a different story.
Serverless functions timing out at 10 seconds. Edge runtime errors with no fs or Buffer. Preview pointing at one database, production at another. Builds hitting the 45-minute limit. Connection pools exhausted under load. We diagnose the Vercel-specific cause and fix it before your next deploy.

Common Vercel Problems We Fix
Vercel is an excellent deployment platform. These are the Vercel-specific issues that stop projects from shipping — all fixable once you know where to look.
Serverless Function Timeout
Vercel API routes default to a 10-second execution limit. Database queries, third-party API calls, and file processing that exceed it return a 504. We restructure long-running operations as background jobs or edge streaming responses.
Wrong Runtime: Edge vs Serverless
Vercel Edge Functions run in a V8 isolate with no Node.js APIs — no fs, no Buffer, no full crypto. Code that works on serverless breaks silently on edge. We audit your runtime assignments and fix the mismatches.
Preview vs Production Env Mismatch
NEXT_PUBLIC_ variables baked at build time mean preview and production can silently point at different APIs or databases. We audit all environment variable scopes and fix the configuration so production behaves correctly.
Build Timeout on Large Projects
Vercel's default build limit is 45 minutes. Large Next.js monorepos with unoptimised ISR pages or heavy static generation hit it regularly. We fix the build pipeline so deploys complete reliably.
Core Web Vitals Failing
LCP over 2.5s, high CLS from layout shift, or slow INP — all caused by Vercel-hosted apps sending too much JavaScript or deferring critical resources. We identify and fix the root causes, not just the symptoms.
Database Connection Pooling
Serverless functions open a new database connection on every invocation. Without a pooler like PgBouncer or Supabase Pooler, you exhaust connections under load. We configure connection pooling correctly for the serverless environment.
