Core Engineering Standard

Reliable systems are never accidental. They are engineered through transactional boundaries, idempotency keys, and bounded recovery for when the unexpected happens.

Featured Implementation

Proof, not empty claims

Real backend architectures with reproducible codebases, verified metrics, and failure recovery.

Software Engineer

Sony India Software Centre

Mar 2025 to Mar 2026 · Bengaluru, India

Internal Java backend services powering PlayStation 4 and PlayStation 5 platform workflows

  • Java 21 migration: Upgraded 10+ production microservices and 3 shared enterprise libraries from Java 8 to Java 21 and Spring Boot 3, successfully resolving javax to jakarta migrations and external dependencies.
  • Performance checks: Profiled services before and after upgrades; tuned JVM garbage collection flags to reduce memory usage and minimize latency across console backend workflows.
  • Testing and security: Authored unit and integration test suites using JUnit 5 and Mockito; embedded SCANOSS scans into delivery pipelines to block vulnerable dependencies and licensing conflicts.
  • Build pipelines: Transitioned CI CD workflows from One Jenkins to Core Jenkins for native Java 21 compilation; automated multi module Maven builds, containerization, and AWS ECR publishing.
  • Observability: Maintained and monitored microservices on AWS EKS using Skuba, Prometheus, and Grafana for metrics, distributed logs, and health alerts.
  • Production releases: Executed zero downtime production deployments adhering to CAB approval governance and automated AutoCD pipelines with rigorous post deployment verification.
