Associate Software Engineer

Oracle Financial Services Software (OFSS)

Jul 2024 - Present

Own end-to-end delivery of 2–3 Spring Boot microservices across the full SDLC (design through production support), powering financial workflows that process over 10,000 daily transactions using Java, REST APIs, PostgreSQL, and Oracle DB. Independently diagnosed a REST API performance bottleneck through query and payload analysis, then partnered with senior engineers to resolve it via SQL query optimization, indexing, and payload tuning — improving response times by up to 50% while preserving backward-compatible API contracts. Built secure backend services using JWT authentication, OAuth2 authorization, Spring Security, and role-based access control, applying internal conventions and industry best practices with minimal day-to-day supervision. Contributed to architecture and design discussions for a banking data migration, then authored PL/SQL migration packages and an asynchronous processing microservice to parallelize record-by-record API calls — migrating 30,000+ records with zero production defects while maintaining transactional integrity. Investigated production issues through log analysis and root-cause debugging, delivering fixes that improved application reliability; authored execution runbooks to document the migration workflow for the team. Collaborated with QA engineers, product managers, and client teams in Agile sprints — driving code reviews, Git workflows, CI/CD pipelines, and release deployments.
