Senior Software Engineer at Anugraha Exceed Incorporated, Oct 2025 - Present · 11 mos, Bengaluru, Leading backend migration of core modules (Curriculum, Logbook Items) from a legacy Hibernate Criteria/HQL architecture to Spring Data JPA, using a standardized service pattern across the codebase. Diagnosed and resolved a series of Hibernate/Oracle schema migration failures (ORA-00904, ORA-02268, ORA-02298) during application startup, recommending a shift from ddl-auto: update to versioned Flyway/Liquibase migrations. Designed a normalized multi-client document management schema to unify divergent folder structures across enterprise clients.

Migrated legacy permission-mapping logic (~150 URL-based IDs) into a new menu-based access model, designing a runtime translation layer inside the security service. Conducted a Spring Boot security architecture review, identifying and fixing filter-ordering and response-encryption gaps. Contributed to the initial Strangler Fig migration architecture — Nginx reverse proxy, Spring Session JDBC, and a React frontend — for transitioning from a legacy MVC platform to Spring Boot.
