Startup Next/Nest Full-Stack Build

I am rolling out the first production version of our startup’s platform and I need an extra pair of hands to push it over the line. The stack is locked in: the front end is Next .js, the back end is Nest JS, and we are using both Postgres and MongoDB where each makes the most sense... (Budget: ₹1500 - ₹12500 INR, Jobs: AngularJS, Docker, Express JS, JavaScript, Nest.js, Next.js, Node.js, PostgreSQL)
