Project details
I am Rasheed, a Senior NestJS Backend Engineer with 8+ years of experience building production grade REST APIs and backend systems. NestJS is my primary specialization, not a tool I occasionally use. Every API I deliver is modular, typed end to end, and architected for long-term maintainability and scale.
What sets this service apart is depth. I do not just write endpoints. I design the full NestJS module structure, enforce clean separation of concerns, implement proper authentication and role-based access, integrate third-party services cleanly through NestJS, and cover critical flows with tests. You get a backend built the way a senior engineer would build it, not a junior developer copying documentation.
Before writing a single line of code I confirm scope, align on architecture, and flag risks early. During delivery I communicate proactively and never disappear mid-project. At handover you receive source code, documentation, and a Postman collection so your team can take full ownership immediately.

Full-Stack Developer Needed for Gaming Marketplace MVP
Rasheed was an outstanding developer to work with. He demonstrated strong technical expertise in React, Next.js, and NestJS, and consistently delivered high-quality work throughout the project. Communication was excellent, deadlines were met, and he was proactive in finding solutions whenever challenges came up.
What impressed me most was his attention to detail and commitment to delivering a polished product rather than just completing tasks. He took ownership of the project, provided valuable suggestions, and ensured everything worked smoothly from start to finish.
I would gladly work with Rasheed again and highly recommend him to anyone looking for a skilled, reliable, and professional full-stack developer.

NestJS developer for a Scalable REST API Backend with Payment Integration and Role-Based Access
Rasheed delivered exactly what we needed and even went beyond that. He handled everything independently without needing constant guidance, which made the whole process smooth. What really stood out was the way he approached the architecture of the system. His communication was clear and proactive throughout the project, and he asked the right questions from the beginning to make sure everything was built the right way. If you’re building something serious with NestJS and need someone who can truly take ownership of the backend from start to finish, Rasheed is definitely the person you want on your team
About Rasheed
Stripe & Payments Backend Developer | Node.js, NestJS, REST APIs
100%
Job Success
Lagos, Nigeria - 4:25 pm local time
losing it , Stripe, PayPal and Paystack in Node.js and NestJS plus the APIs,
queues and databases around them. Around $2.9M processed. Never a double charge.
"I am really pleased with this one and he understands his craft, would come back
for sure." — Upwork client
The busiest system I've built runs about 3,000 orders a day and pays vendors out
across two gateways. It has never double-charged anyone, and that isn't luck:
every webhook handler is idempotent and every transaction is reconciled against
the gateway.
Sounds basic. It's what most integrations get wrong.
WHERE PEOPLE USUALLY FIND ME
Something is broken and it's costing money. Payments failing silently. Vendors paid the wrong amount. Webhooks missed. Subscriptions not renewing. A queue dropping jobs nobody noticed. Numbers that don't reconcile against Stripe.
Or the backend itself is the problem. Endpoints that got slow as the data grew.
A schema that buckles under concurrent writes. Auth bolted on late. A codebase
someone else left behind with no documentation and no tests.
Or you're building something new and you want someone who'll say "this requirement is going to bite you" before the first commit, not after the first 2am incident.
PAYMENT WORK
- Stripe Checkout, Payment Intents and custom checkout flows
- Stripe Connect marketplaces, split payments and vendor payouts
- Subscription and recurring billing, including failed renewals and retries
- Webhook architecture with idempotency, replay handling and signature
verification
- Payment reconciliation against gateway settlement data
- Refunds, disputes and partial captures
- PayPal REST API, standalone or alongside Stripe so customers pick at checkout
- Paystack — where I started, and still the highest-volume system I run
- International and multi-gateway payouts
BACKEND WORK
Payments are the specialty. They are not the whole job, and most of my contracts cover the rest of the backend too.
- REST and GraphQL APIs in NestJS and Express, typed end to end in TypeScript
- Multi-tenant SaaS backends with roles, permissions and tenant isolation
- Authentication and authorisation: JWT, sessions, guards, API keys, RBAC
- PostgreSQL and MongoDB schema design that holds up under concurrent writes
- Background jobs and event-driven queues in BullMQ and RabbitMQ, with real
retry, backoff and dead-letter handling
- Redis caching and rate limiting
- WebSockets for live updates
- Third-party API integrations and webhook receivers that survive the other
side going down
- OpenAI and Claude features wired in so a model timeout doesn't take the whole
request with it
- Data and analytics backends: ingestion, aggregation, reporting endpoints
- Performance work: slow endpoints, N+1 queries, lock contention, bad indexes
- Taking over an undocumented codebase and making it safe to change
- AWS, Docker, CI/CD and staging environments that mirror production
Six years of this. Node.js, NestJS, Express, TypeScript. E-commerce, real estate, fintech, gaming marketplaces and media platforms. I've worked with teams in Lagos, London and the US.
WHAT WORKING WITH ME IS LIKE
Before I write anything I'll tell you honestly whether it's a three-day fix or a three-week build. If your requirement has a problem in it, you'll hear about it before I start, not in the retro.
Clients here have endorsed me as a clear communicator, detail oriented and accountable for outcomes. One described the work as "clean" and "very timely on delivering." Another said I "delivered exactly what we needed and even went beyond that... handled everything independently without needing constant guidance."
I write tests, type everything, and leave documentation your next developer can actually use. I cover US, UK and EU hours and reply within a day.
TRY ME FIRST
If something is broken: send me the error log, the failing webhook, the slow endpoint, or a link to the repo. I'll tell you what I think is actually causing it, roughly how long it takes to fix, and the one thing I'd flag before you start. No charge, no obligation to hire me.
If you're building something new: send me one sentence about what it is, and I'll tell you straight whether I'm the right fit and what I'd want to nail down before the first line of code.
Steps for completing your project
After purchasing the project, send requirements so Rasheed can start the project.
Delivery time starts when Rasheed receives requirements from you.
Rasheed works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements Review
I review everything you have shared, ask any clarifying questions, confirm the scope, and align on the architecture approach before writing any code.
Architecture and Module Design
I design the NestJS module structure, database schema, API endpoints, and authentication flow, and share it with you for confirmation before development begins.
