Prisma Connection Pool Exhausted - Cannot Connect to Database
API requests start failing with 'too many connections' or 'connect ECONNREFUSED' errors. The database was working fine but suddenly stops accepting connections.
This typically happens under load or after the app has been running for a while, and restarting the app temporarily fixes it.
Error Messages You Might See
PrismaClientInitializationError: Can't reach database server at `localhost`
Error: too many connections for role
Error: connect ECONNREFUSED 127.0.0.1:5432
Common Causes
- Prisma Client not being reused across requests - creating new instances continuously
- Database connection pool size too small for concurrent requests
- Connections not being closed properly after queries
- Long-running queries holding connections idle
- Pool timeout set too low, causing connection exhaustion
How to Fix It
Create a singleton Prisma Client instance: export const prisma = new PrismaClient(); // import in routes
Configure connection pool in DATABASE_URL: postgresql://user:pass@host/db?schema=public&connection_limit=5
Add proper error handling and disconnect: process.on('SIGINT', async () => { await prisma.$disconnect(); })

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.

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.**

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.

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)
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
What's the best way to use Prisma in serverless?
Create a singleton pattern with module-level instantiation to reuse connections across cold starts
What's a safe connection pool size?
For WebContainer: 2-3. For production: 10-20. Adjust based on concurrent users and query patterns
How do I debug connection issues?
Enable Prisma debug logging: DEBUG=prisma:* npm run dev
