You will get a production-ready REST API in Node.js and TypeScript
Project details
I'll build your REST API in Node.js and TypeScript — clean, typed, and production-ready, built to the same standard as systems serving 1M+ users.
Scope of work:
• RESTful endpoint design with proper HTTP semantics
• Input validation and centralized error handling
• JWT authentication (Standard & Premium)
• MySQL or PostgreSQL integration
• Postman collection for every endpoint
• Organized, scalable folder structure
I have 2+ years building backend systems in production — including a multi-tenant platform serving over 1 million users across 7,000+ institutions. Your code will be written to the same standard.
Basic: 3 endpoints
Standard: 8 endpoints with auth
Premium: Full module (15+ endpoints), auth, pagination, documentation
Message me to confirm your requirements fit the package before purchasing.

Ahsan delivered a high-quality full-stack application very quickly with excellent communication and clear understanding of requirements. Highly recommended.
About Ahsan
Senior Backend Engineer | Node.js | API Design & Payment Integrations
Sylhet, Bangladesh - 1:22 am local time
with a high-traffic backend that is slowing down under real load?
I am a Senior Backend and Full-Stack Engineer specializing in production-grade
Node.js and Next.js systems. Over the past two years, I have engineered
multi-tenant architectures for software platforms serving 1,000,000+ students
across 7,000+ institutions — handling $100,000+ in monthly revenue at 99.9%
uptime.
When you hire me, you are not hiring someone to write code. You are hiring an
engineer focused on business outcomes, data integrity, and cost efficiency.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I DO BEST
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
▸ Payment & Billing Infrastructure
Unified processing layers across Stripe, Paddle, and Xendit — with
fail-safe webhook architecture that eliminates double-charging and
partial-write data corruption.
▸ Database Optimization
I rescue slow APIs. Through composite indexing, query rewrites, and
schema redesign, I consistently reduce MySQL response times by 10–30%
on the highest-traffic production endpoints.
▸ SaaS & Multi-Tenant Architecture
Secure Role-Based Access Control, real-time connection-pooled services,
and multi-tenant systems designed for scale from day one.
▸ Cloud Cost Optimization
Migrated transactional email infrastructure to AWS SES and moved asset
storage to AWS S3 — reclaiming 14+ GB of production database storage
and cutting ongoing vendor costs.

PRODUCTION METRICS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✔ $100,000+ monthly revenue handled at 99.9% uptime
✔ 1,000,000+ users across 7,000+ institutions on a single platform
✔ 14+ GB of database storage reclaimed via S3 migration
✔ Real-time services stabilized under thousands of concurrent connections

Backend → Node.js, Adonis.js, Django, REST API, Webhooks, Redis
Frontend → React.js, Next.js, Redux, TypeScript
Database → MySQL (Atomic Transactions, Composite Indexing), Redis
Cloud → AWS SES, AWS S3, Docker, Linux
Other → Codeforces Specialist (1400+ rating) — strong algorithmic
problem-solving background

If you need an engineer who takes full ownership of your backend, understands
real-world scalability, and ships systems that survive production traffic —
let's talk.
Steps for completing your project
After purchasing the project, send requirements so Ahsan can start the project.
Delivery time starts when Ahsan receives requirements from you.
Ahsan works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements Analysis & Architecture Design
I review your data requirements, map out the endpoint routes, and design the database schema layout (MySQL/PostgreSQL) to ensure a scalable architecture before writing any code
Environment Setup & Base Architecture
I configure the Node.js and TypeScript environment, establish an organized folder structure using SOLID principles, and set up centralized error handling and input validation layers.
