Production Experience Deep Dive

Sony India Software Centre · PlayStation Platform Services

Architectural modernization and infrastructure reliability for core Java services backing PlayStation 4 and PlayStation 5 platform workflows.

• Java 21 & Spring Boot 3 Upgrade: Transitioned 10+ production microservices and 3 shared internal libraries from Java 8. Resolved complex javax to jakarta namespace relocations and upgraded third party dependencies with zero system regressions.
• Garbage Collection & Latency Tuning: Ran comparative profiling before and after runtime migration. Tuned ZGC and G1GC parameters to minimize tail latency and optimize RAM consumption across console backend workflows.
• Quality & Supply Chain Security: Established comprehensive unit and integration test suites using JUnit 5 and Mockito. Integrated SCANOSS scans directly into Jenkins CI CD pipelines to identify vulnerable dependencies and license compliance violations before deployment.
• Pipeline Modernization: Migrated legacy build automation from One Jenkins to Core Jenkins for native Java 21 compilation. Automated multi module Maven builds, Docker container creation, and artifact publishing to AWS ECR.
• Telemetry & Cluster Health: Supported containerized microservices hosted on AWS EKS. Created Grafana dashboards, Prometheus metric scrapers, and configured Skuba tooling for observability.
• Governance & Releases: Successfully drove production deployments through CAB approval gates and automated AutoCD pipelines with robust post deployment validation checks.

Quantum Wave · Backend & Integration

• API Engineering: Developed RESTful endpoints with strict OpenAPI request contracts, robust field validation, and token based authorization.
• Client Layer Integration: Engineered the Angular and TypeScript client architecture using RxJS reactive streams, centralized HTTP interceptors, and unified error boundaries.
• Payload & Query Optimization: Reduced redundant queries and network payload overhead by implementing server side cursor pagination, filtering query parameters, and cache layers.
• Agile Delivery: Participated in sprint planning, relational schema reviews, unit test implementation, and pull request reviews in an Agile workflow.
