This is how you will grow:

We are seeking a highly skilled expert to develop and own the migration of our existing NestJS services

to a Java-based microservices architecture. In this role, you will lead the entire migration process—from

planning and design to backend development, execution, and final delivery—ensuring a seamless

transition and minimal disruption to our services.

Complete Code Migration

o Rewrite and refactor NestJS (TypeScript) backend services into Java microservices (e.g.,

Spring Boot).

o Ensure minimal service disruption and maintain backward compatibility.

Architecture & Design

o Independently define and implement the new Java microservices architecture.

o Set best practices for microservices communication, data management, and

performance optimization.

Testing & Validation

o Write comprehensive tests (unit, integration, performance) to validate the migrated

codebase.

o Ensure the system meets reliability and performance benchmarks expected in

automotive supply chain solutions.

Documentation

o Document the new architecture and migration process to enable future maintenance

and enhancements.

o Provide regular status updates to stakeholders on migration progress, risks, and

timelines.

Troubleshooting & Maintenance

o Diagnose and fix issues that arise during the migration, ensuring a stable release.

o Provide knowledge transfer or handover documentation upon contract completion.
