Upgrade MySQL and Node.js To Latest Versions
Neha did an excellent job upgrading our node.js API to the latest versions. Despite us providing a lot of information and code without tons of explanations or unit tests, she managed the process independently, handled the challenges effectively, and resolved the necessary bugs.

Job Success
Ahmedabad, India - 9:24 pm local time
I'm Neha, a Node.js Backend Developer and Backend Systems Architect with 9+ years shipping production systems that hold up under real load — across fintech, healthcare, e-commerce, real estate, travel, and e-learning. I've taken products from pre-launch to 50M+ requests/month and 100M+ rows without rewrites.
The pattern I'm hired to prevent: a PostgreSQL table that's fine at 10K rows and a problem at 10M, an API that drops connections at 500 concurrent requests, a Stripe integration that breaks the moment a card fails mid-subscription. These aren't edge cases — they're the normal lifecycle of a growing product, and the backend has to be built for them from day one.
What I do:
• Scalable REST APIs & microservices in NestJS, Express.js, and TypeScript — designed around your actual load and data patterns, type-safe, and readable for the next dev.
• AWS production infrastructure — EC2, ECS, Lambda, RDS (PostgreSQL with proper pooling, backup, failover), and API Gateway, plus repeatable CI/CD on GitHub Actions and GitLab.
• Database performance — PostgreSQL and MongoDB schema design, indexing, and query optimization on live systems with no downtime. (Recently cut a client's slowest endpoint from 4.2s to 180ms — a single N+1 query buried in a dashboard load — without any downtime on the live system.)
• Payments & integrations — Stripe, RevenueCat, Razorpay, and Meta APIs done properly: subscriptions, trials, upgrades, failed-payment recovery, and reliable webhooks.
Before I touch code I map the full backend — data models, API contracts, third-party dependencies, caching strategy, and the two or three places likely to break under load. That conversation upfront saves weeks of reactive fixes later.
If you've got a backend that's slowing down, a scaling deadline coming, or a payment flow that's drifting out of sync — send me the specific pain point and I'll tell you how I'd approach it.
