You will get a production Node.js or NestJS backend and REST API
Project details
Most backends work fine until they meet real users. Then the same request arrives twice and creates two records. A missing index turns a 40ms query into 4 seconds. A validation gap lets a negative amount into the database. None of it shows up in a demo.
I build backends meant to survive that. TypeScript throughout so shape errors surface at compile time rather than in production. PostgreSQL with Prisma, with constraints enforced by the database instead of hoped for in application code. Validation at the boundary, so bad input never reaches your business logic.
You get authentication and role-based access, input validation on every endpoint, sensible error handling, and API documentation your frontend team can work from without asking you questions. Deployed and running on your infrastructure, not handed over as a zip file.
I have spent 7+ years on production Node.js systems. I currently own the backend across 15+ services on a US-based multi-tenant SaaS platform, and I have built and shipped backends for remittance, ticketing, education, and dating products.
Tell me what you are building and I will tell you honestly whether the scope fits the tier you are looking at.

In need of a Web developer
Enow Divine is a skilled and wonderful person with great personality and work ethics. He did his job excellently well and on time, and even notifies me early enough if he thinks a task may take a longer time period and also provide me with details why it will take longer than expected. I think his a great person to work with and would hire him again if I need his services.
About Enow Divine
Senior Full-Stack Engineer | Node.js, TypeScript, React | Payments
Douala, Cameroon - 4:32 pm local time
Payments are where small bugs get expensive. A duplicated webhook. A race condition on a balance. A field rename that silently changes the meaning of a transaction.
I've spent 7+ years building systems designed to prevent those problems: idempotent payment flows, immutable audit trails, and state machines that keep transactions consistent under load.
What I do
* Payment integrations: card processors, mobile money, and multi-currency remittance corridors
* Node.js / TypeScript backends using REST and event-driven architectures, with PostgreSQL and Prisma
* Microservice architecture. I currently own the backend across 15+ services for a US-based multi-tenant SaaS platform
* Full-stack delivery when needed with Next.js, React, and React Native
Things I've built and shipped publicly
* stateledger: a TypeScript state machine library for payment workflows, published on npm and GitHub
* PulseLab: a webhook and WebSocket debugger for developers
* SS Invoice: mobile money invoicing for small businesses
The code is part of the portfolio. You can look through it before you hire me.
Recent client work
* Multi-corridor remittance platform covering Bahrain, the UK, Ukraine, and Canada to Cameroon, with live FX rates, admin approval flows, and proof-of-payment handling
* Event ticketing platform with payment splits and payouts
* Education pathways platform for a licensed Cameroonian company
* Additional client work under confidentiality. I'm happy to walk through the architecture on a call.

I work remotely with US and EU teams and usually respond within a few hours.
I'm also comfortable saying when a scope is unrealistic. I'd rather catch that before development starts than discover it three weeks into the project.
If you're building something where money changes hands, send me the details. I'll tell you honestly whether I'm the right fit.
Steps for completing your project
After purchasing the project, send requirements so Enow Divine can start the project.
Delivery time starts when Enow Divine receives requirements from you.
Enow Divine works on your project following the steps below.
Revisions may occur after the delivery date.
Scope and data model
I map your entities, their relationships, and the actions users take, then design the schema. Getting this right first prevents most of the rewrites that happen later.
Build the API
I implement the endpoints with authentication, role-based access, and validation at every boundary, on PostgreSQL with Prisma.
