RH Partner is an HR and payroll SaaS. At Tech-Instinct I maintained and extended its production Spring Boot REST microservices, each deployed in its own Docker container, and worked on the schemas, queries and tests behind them.

The context

RH Partner was already in production. The work was to maintain and extend its backend services, not to rebuild them.

The services

  • Maintained and extended the Spring Boot REST microservices behind the product.
  • Each service runs in its own Docker container, alongside SQL Server in Docker.
  • APIs secured with JWT.

Making queries faster

I designed database schemas and optimised SQL queries, which made the affected queries about 35% faster.

Tests and releases

  • Wrote JUnit unit and integration tests, reaching over 90% coverage in the tested scope.
  • Resolved production defects to keep releases reliable.

What this shows

Backend work on a live product in a second stack: Java and Spring Boot services, containerised, measured on query speed and test coverage.
