About The Project

Worked as a Full Stack Developer at Nivan Tech, redesigning and re-implementing services using modern technologies including NGINX, Node.js, Express.js, MongoDB, and MySQL. Built frontend applications with Angular and TypeScript while creating scalable RESTful web services.

Optimized microservices architecture using Node.js with Cassandra NoSQL database interfaces. Collaborated closely with systems analysts, engineers, and programmers to resolve software problems and develop new capabilities. Implemented Object-Oriented Programming principles and created custom Node.js modules extending core functionality, managed with version control tools like SVN and Git.
