About this gig
Your frontend is built but there is nothing behind it. Your Stripe webhooks fail silently and you hear about it from customers. A cron job stopped weeks ago and nobody noticed.
That is the work I do: backends that hold up when real users and real money hit them.
Message me before you order. I will review what you have, show you exactly what is broken or missing, and send a plan with a custom offer.
Senior backend developer, 8 years. I owned a Node backend processing millions of records a month, with queue workers running 100 plus jobs in parallel and live integrations across Gmail, Microsoft Graph, and AWS.
What I build and fix:
REST APIs in Node, Express, and NestJS
PostgreSQL, MongoDB, and Redis: schema design, migrations, slow queries
Stripe checkout, subscriptions, and webhook handling that does not double charge
Third party integrations that stay connected
Cron jobs and background workers with retries, logging, and failure alerts
AWS deployment, environment config, and monitoring
Full source code and documentation on every order.
Message me first with what you have. The review is free.

Hiring a developer and hoping the app actually works when real users hit it? That's the gap I close. I'm a senior full-stack developer (8 years) building production web apps, SaaS platforms, and React Native mobile apps in React, Next.js, and Node.js.
I've built systems processing millions of records a month, recovered a breached FinTech platform in 72 hours, and shipped products across FinTech, HealthTech, and SaaS. I own the whole build - frontend, backend, database, deployment - with clean, maintainable code.
Tell me what you're building, and I'll tell you exactly how I'd do it.

FAQ
Do you work with an existing backend or only build new ones?
Both. I regularly take over existing Node, Express, and NestJS codebases, including ones another developer left half finished. Send me the repo and I will tell you what state it is really in before you order.
Can you fix Stripe payments and webhooks?
Yes. Checkout, subscriptions, webhook signature verification, retries, and the idempotency handling that stops double charges. Most Stripe problems I see come down to unverified or unhandled webhook events.
What about scheduled jobs and background workers?
Yes. Cron jobs, queue workers, and long running background tasks built with retries, failure alerts, and logging, so you find out when something stops instead of discovering it weeks later.
Which databases do you work with?
PostgreSQL, MongoDB, and Redis. That includes schema design, migrations, indexing, and fixing slow queries, not just basic CRUD.
Should I message you before ordering?
Yes, please do. I will review what you have, tell you what is broken or missing, and send a plan with a custom offer, so the scope is agreed before any money changes hands.
