Hurry! Only 2 project slots left this week. Secure your code delivery before the deadline hits.
Node.js Capstone HelpScalable Backend & API Architecture.
Struggling with Express middlewares, database migrations, or authentication? Get professional Node.js backend support to secure your grade.
The Challenge
API returning 500 errors? Database queries timing out at the worst moment?
Middleware Chaos
Express middleware execution order is wrong, CORS is blocking your frontend, and error handlers never catch anything.
Database Disasters
Migrations failing, foreign key constraints breaking inserts, and N+1 query problems tanking your response times.
Auth Failures
JWT tokens expire mid-session, bcrypt comparisons return false on correct passwords, and OAuth callbacks loop forever.
Deployment Crashes
Works on localhost but crashes on Heroku/Render. Missing environment variables, port binding errors, and memory leaks in production.
Real Node.js Project Examples
Recent systems and components we have rescued or built from scratch.
Express Middleware Refactor
Rewrote chaotic Express.js authentication middleware, properly handling async/await rejections to prevent silent server crashes during invalid token requests.
PostgreSQL N+1 Query Fix
Optimized a social media API endpoint that was making 500 database calls per request down to 2 optimized Prisma queries, dropping response time from 4s to 120ms.
Targeted Node.js Support
I design RESTful APIs with proper error handling, efficient database queries, secure authentication flows, and deployment configurations that survive real-world traffic.

Frequently Asked Questions about Node.js
How do you fix Node.js memory leaks?
Quick Answer: We use tools like clinic.js and node --inspect to take heap snapshots, identifying unclosed database connections, global variables, and lingering event listeners causing the leak.
Can you help deploy my Node.js API to Heroku or Render?
Quick Answer: Yes. We write proper start scripts, configure environment variables, setup PM2 or Docker, and ensure your Node server binds to the correct dynamic port for cloud deployments.
