You will get a full stack web application with NextJs, Node.js and PostgreSQL
Project details
I will build a fast, reliable full-stack web app tailored to scale with your business—built to the same engineering standards as systems serving 1M+ users.
Scope of work:
• Responsive, mobile-friendly UI (React/Next.js)
• Secure, type-safe REST API & database design (SQL/NoSQL)
• Clean, documented code & scalable structure
Basic: Core CRUD app (up to 3 views/endpoints)
Standard: Full app (up to 8 views) with secure auth & dashboard
Premium: Complete SaaS (15+ views/endpoints), auth, analytics & payments
I work across modern JavaScript and Python ecosystems—leveraging Next.js, React, Node.js, Express, FastAPI, and Django. For storage, I use PostgreSQL, MySQL, or MongoDB, selecting the right database for your specific needs.
I bring 2+ years of production experience, including core architectural contributions to a multi-tenant platform serving over 1 million users across 7,000+ institutions. Your code will be written to that exact standard.
Message me to confirm your requirements fit the package before purchasing. Let's build something great together.

Full stack web
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 - 6:21 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

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.
