Vercel Serverless Function Timeout - API Routes Taking Too Long
API routes that work fine locally timeout on Vercel. Long-running tasks like file processing, bulk database operations, or external API calls exceed the timeout limit.
Requests return 504 Gateway Timeout and logs show the function was killed.
Error Messages You Might See
504 - Gateway Timeout
FETCH_ERROR: request timeout
Function timeout after 30s
Vercel Serverless Function Error: timed out
Common Causes
- Function execution time exceeds timeout (default 30s, max 60s on Pro)
- Waiting for slow external API calls without timeout
- Database query not optimized or hitting connection limits
- Large file processing happening synchronously
- Missing async/await causing hanging requests
How to Fix It
Upgrade to Vercel Pro for 60s limit (free tier is 30s max)
Add timeout to external calls: fetch(url, { timeout: 10000 })
Use background jobs for long tasks - trigger async processing, return immediately
Optimize DB queries: add indexes, use pagination for large result sets
Consider moving heavy lifting to cron jobs or separate worker services

Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

Vlad Temian
15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

Get HelpFrequently Asked Questions
What's the maximum timeout on Vercel?
Free: 30s. Pro: 60s. Enterprise: up to 5min
How do I handle long-running tasks?
Trigger them asynchronously. Save a job record to DB, return immediately, process in background
Should I wait for all async tasks?
No! Return response to user, then run cleanup/processing. Use background jobs for long tasks
