You will get Node.js & NestJS Engineer | Scalable APIs & SaaS Backends
Project details
Most backend failures come from poor choices nobody caught until the system was under load. I catch those before they become your problem.
I am a Node.js and NestJS Engineer specializing in Scalable APIs and SaaS Backends. I build server side systems that are structured, secure, and built to grow with your product.
☑ What I build:
✔ Scalable REST APIs using Node.js and NestJS
✔ SaaS backend architecture with clean modular structure
✔ Socket.io real time features and live event systems
✔ Firebase with Firestore and real time database
✔ MongoDB, MySQL, and PostgreSQL database design
✔ Express.js services and middleware configuration
✔ Secure authentication and third party integrations
✔ I ship on time and never close until you are fully satisfied.
💡 Let us talk and build a backend that holds up.

Full Stack React & NestJS Developer | Microservices & Scalable APIs

Job Success
Lahore, Pakistan - 10:01 am local time
I am a React and NestJS Developer specializing in Microservices, APIs, and Scalable Backend Systems. I have worked with startups and growing businesses to build full stack web applications that are clean, maintainable, and built to handle real world growth. Whether you are starting from scratch or scaling an existing system, I know how to build the right foundation.
My recent work has focused on distributed backend systems using NestJS, handling service to service communication, event driven architecture, secure authentication flows, and clean modular code patterns that teams can work with long term.
☑ What I can build for you:
→ Scalable backend systems using NestJS and microservices architecture
→ REST APIs and GraphQL APIs built for performance and maintainability
→ Modern frontend applications with React and Next.js
→ Secure authentication using JWT, OAuth2, and session management
→ API integrations with third party services and payment gateways
→ Database design with PostgreSQL, MongoDB, and Redis
→ Docker and containerized deployments for clean environments
→ Event driven communication using RabbitMQ and Kafka
→ Clean architecture patterns including domain driven design and SOLID principles
→ Performance optimization for both frontend and backend systems
I focus on writing code that your team can understand, maintain, and build on top of. Clean architecture is not a buzzword for me. It is the standard I hold every project to, because messy codebases cost far more to fix later than they save in the short term.
If you are building a SaaS product, a marketplace, or any web application that needs a reliable full stack developer with a strong backend focus, I am ready to help you build it right from day one.
