  • Manage the CICD pipeline (for web deployment), come up with improvements, and implement them. 

  • Optimize application efficiency and resolve performance constraints leveraging NestJS capabilities.

  • Stay updated on industry trends and technologies.


  • 3+ years of experience

  • Extensive TypeScript/JavaScript backend development expertise.

  • Demonstrated experience in backend software projects.
