Project details
Struggling with a broken React or Next.js component? I’ll debug and fix one UI issue, such as state errors, rendering glitches, or form submission problems (e.g., like a vertical form layout I’ve built before). As a full-stack developer with expertise in JavaScript, React, and Next.js, I deliver clean, tested code fast. You’ll get the fixed component, a screenshot of the working UI, and one revision. Provide your codebase and a brief issue description, and I’ll resolve it within 24 hours!

Senior Backend Engineer | Node.js | API Design & Payment Integrations
Sylhet, Bangladesh - 8:45 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.
