Node.js Expertise
What I Build With Node.js
APIs that handle production load — not Postman demos. Authentication, caching, documentation, and deployment included as standard.
REST APIs — Production-Grade
Authentication, pagination, rate limiting, input validation, Swagger documentation, and proper error handling. The APIs that stay up when the load spikes at 3am.
GraphQL APIs
Schema-first design, resolver optimisation, DataLoader for N+1 prevention, and subscriptions for real-time data. GraphQL that performs — not just a trendy tech choice.
Microservices Architecture
Event-driven services with Kafka or RabbitMQ, Docker containerisation, inter-service communication, and health checks. Built to scale horizontally, not vertically.
Real-Time Systems
WebSocket with Socket.io, live dashboards, real-time notifications, and collaborative features — built for FinTech platforms where lag costs money.
Authentication & Security
JWT, OAuth 2.0, session management, 2FA, role-based access control, and rate limiting. Security as a first-class requirement, not a post-launch checklist item.
Database-Heavy Backends
Complex PostgreSQL schemas, migrations, query optimisation, Redis caching layers, and Elasticsearch for full-text search. 65% faster queries — already delivered.
Why Hire Me
Backend Work That Holds Up Under Pressure
A Node.js API that passes your test suite is table stakes. One that holds up at 3am, under load, with a partial database failure — that's what I build.
APIs built for 3am — not just for Postman
Retry logic, graceful degradation, circuit breakers, health endpoints, and structured logging. Production APIs need to handle partial failures. I build them that way from the start.
Performance tuned before it's a problem
Redis caching, database indexing, connection pooling, and query analysis are standard — not optional extras. The 65% query improvement was found before the client even noticed slowness.
NestJS module architecture that scales
Not just Express with middleware. NestJS dependency injection, module boundaries, interceptors, guards, and pipes — the architecture that makes a 100K-line codebase manageable.
Deployed on AWS, not just running locally
EC2, RDS, S3, Lambda, CloudWatch — I set up the infrastructure, configure the CI/CD pipeline, and hand over a system you can actually monitor and scale.
Common Questions
Before You Reach Out
The questions every client asks — answered honestly.
How much does a Node.js developer cost?
Fixed-price for scoped API projects — a REST API, an auth system, a microservice. Retainer for ongoing backend development. I quote in writing within 24 hours, with clear scope and no hidden costs.
NestJS or Express — which do you use?
NestJS for projects that will grow — the module architecture, DI, and decorator patterns pay off quickly. Express for simpler APIs where overhead isn't justified. I make the call based on your requirements, not preference.
Can you optimise an existing Node.js backend?
Yes, and it's often where the most value is. Share the codebase or describe the problem and I'll assess what's causing the slowness — whether it's missing indexes, N+1 queries, no caching, or architectural debt.
Do you write API documentation?
Swagger/OpenAPI documentation is standard on all API projects — not an optional extra. Every endpoint gets request/response schemas, error codes, and authentication requirements documented.
Can you handle both the front-end and back-end?
Yes — full-stack means full-stack. React or Next.js on the front-end, Node.js on the back-end, PostgreSQL or MongoDB, deployed to AWS or Vercel. One engineer, one invoice.
How do you ensure API reliability?
Structured error handling, input validation (Zod or class-validator), rate limiting, health check endpoints, and CloudWatch or similar monitoring are standard. I set up alerting before the API goes live.
