Builds secure NodeJS/Express microservices and REST APIs, then wires them to React 19 front ends, databases, Kafka/third-party services, and CI/CD while doing code reviews, testing, and production troubleshooting.
"Build scalable and secure RESTful APIs using NodeJS, ExpressJS and Microservices architecture."
Tech stack maturity
Mainstream Modern
The stack centers on widely adopted modern web and backend technologies like Express.js, Node.js, TypeScript, Kafka, microservices, REST, and React, which are common in contemporary production systems rather than bleeding-edge or legacy environments.
