Work Experience

Feb 2023 - Oct 2024

Built a Spring Boot microservice with JWT authentication and 3-tier RBAC, enforcing manager-scoped, hierarchy-aware authorization for shift and leave approvals. Added circuit breaker and retry around payroll submission — so attendance still saves even if payroll is down, with failed submissions auto-retried later. Built an event-driven scheduling platform using Kafka to decouple shift creation from notification, caching, and payroll consumers via a partitioned event topic. Design and developed RESTful APIs using Spring Boot for employee leave and absence tracking workflow.
