At RHIS SOFTWARE, I architect and maintain Spring Boot microservices for enterprise HR systems. I delivered secure authentication for 500+ users using Spring Security and JWT.
I improved API response time by ~30% through DTO redesign and query optimization. I also automated payroll integration with the Silae API, reducing manual processing errors by ~35%.
I enhanced scheduled cron performance by ~40% through batching and database optimization, and deployed Dockerized services on Linux with Nginx and Caddy.
On the OSM – Olive Supply Management System project, I architected microservices for delivery, lot grouping, and quality control workflows. I implemented rule-based lot assignment and developed Angular modules for stock and production planning.
