Senior Node.js / NestJS Backend Engineer Needed (TypeScript, PostgreSQL)
I had an excellent experience working with Nokhaiz. Their expertise in Node.js, NestJS, and PostgreSQL is outstanding. They delivered clean, maintainable code, optimized our backend performance, and implemented features efficiently. Communication was clear, and they consistently provided thoughtful solutions to complex problems. Highly recommended for any backend project!

Delayed work. I extended what was a 15 day project to 2 months. He kept promising me he will deliver. I even paid another developer to give me the integral code of my project . The other developer charge 1/20th of the price and delivered in a day and Syed even after two weeks of giving it has been unresponsive and didn't care one bit about the schedule or the deadline. I counted exactly how many remainders I sent him. Totally 11 times 'Syed??' . He responds every time and makes empty promises , I am at the end of my deadline and i cant waste anymore time on his empty promises

Lahore, Pakistan - 5:13 am local time
With 8+ years of experience in Node.js, NestJS, and TypeScript, I specialize in building scalable REST & GraphQL APIs, microservices architectures, and cloud-native systems that handle high concurrency and real-world production workloads.
I focus on clean architecture, performance optimization, and long-term maintainability, not just feature delivery.
