Vercel Serverless Function Timeout
Your Vercel serverless functions timeout before completing (504 Gateway Timeout), cutting off long-running operations like data processing, report generation, or large data fetches.
Timeouts occur when functions exceed Vercel's limits (10 seconds for Hobby, 60 seconds for Pro), or when operations are inherently slow.
Error Messages You Might See
504 Gateway Timeout
Function execution timeout
[Vercel] Task timed out
Kill signal received
Common Causes
- Long-running operations not fitting within timeout limits
- External API calls not timing out, blocking function execution
- Large data processing, image manipulation, or file generation taking too long
- Database queries slow due to missing indexes or N+1 queries
- Not using Vercel's async job queue or background jobs for long tasks
How to Fix It
Upgrade plan: Hobby plan has 10s limit, Pro has 60s. Check plan limits in Vercel docs.
Add timeouts: Set timeout on external calls: const res = await fetch(url, { signal: AbortSignal.timeout(5000) })
Use background jobs: For tasks > 60s, use Vercel's Cron or external job queue (Bull, Inngest).
Optimize queries: Add database indexes, fix N+1 queries, use caching to speed up slow operations.

Hi Im a full stack developer, a vibe coded MVP to Market ready product, I'm here to help
Basel Issmail
’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

I'm a backend developer building APIs, emulators, and interactive game systems. Professionally, I've developed Java/Spring reporting solutions, managed relational and NoSQL databases, and implemented CI/CD workflows.
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.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
Can I increase the timeout limit?
Hobby: max 10s. Pro: max 60s. To exceed, use background jobs or external processing (e.g., Firebase Cloud Functions).
What should I do for long-running tasks?
Use Vercel Cron for scheduled jobs, or queue library like Bull/Inngest for async tasks that run outside request context.
How do I debug timeout issues?
Add console.log timestamps to find slow sections. Use Vercel Analytics to see function duration. Optimize the slowest part.
