Full-Stack Developer - NestJS & Python/FastAPI

About the Role

Provis Technologies is hiring a hands-on Full-Stack Developer who can build and deliver production features across frontend applications, backend services, databases, and third-party integrations.

This is a dual-backend role. Candidates must have practical development experience with both:

• NestJS and Node.js
• Python and FastAPI

Candidates who have experience with only one of these backend stacks will not be considered.

You will work on AI assistants, SaaS platforms, B2B portals, internal dashboards, and workflow automation products using Next.js, React, TypeScript, Tailwind CSS, NestJS, Python, FastAPI, PostgreSQL, and Docker.

This is not a training-only position. You must be able to understand an existing codebase, take ownership of a feature, test it locally, debug issues across services, and deliver reliable changes with limited hand-holding.

Key Responsibilities

• Build responsive screens, dashboards, forms, and workflows using Next.js, React, TypeScript, and Tailwind CSS.
• Design, extend, and debug REST APIs and business logic using NestJS and Node.js.
• Build and maintain Python services and APIs using Python and FastAPI.
• Connect NestJS and Python services within the same product architecture.
• Troubleshoot frontend, backend, database, API, and cross-service issues.
• Work with PostgreSQL, including schema design, SQL queries, joins, indexes, transactions, and migrations.
• Integrate third-party APIs such as LLM providers, messaging…
