I'm building the eBDN application for ZeroNorth at WCS, supporting digital bunker delivery workflows for the shipping industry. The platform captures bunkering data and produces digitally signed reports for stakeholders including Singapore's Marine Port Authority.

I designed multi-tenant workflows with Spring Boot tenant context management and dynamic data source routing, and helped migrate infrastructure from on-premise VMs to AWS. I also implemented JWT authentication, refresh tokens, REST APIs, and IndexedDB caching for stronger security, offline usability, and fewer repeated API calls.

On the Angular side, I've built reusable validation frameworks, workflow indicators, shared UI components, and deployment-update detection utilities. By optimizing rendering and unnecessary API interactions, I improved frontend performance by 30% and scrolling performance by 50%.

Previously at TCS on BT, I developed REST APIs, GraphQL queries and mutations, global search, and integrations with external microservices. I improved report generation through asynchronous processing, materialized views, and database optimization, while using AWS ECS and CloudWatch for deployment monitoring and troubleshooting.
