What I'm looking for

I’m looking for work where I can build and integrate backend services with Java/Spring, design reliable asynchronous workflows, and ship features that support high-volume document generation and exports.

At Veersa Technology, I build backend services with Java, Spring Boot, and PostgreSQL for Neovance eCRM—a multi-tenant CRM with role-based access control and data isolation.

I designed a docx-based document generation system with docx4j, supporting dynamic placeholders for text, images, lists, and tables, used at high daily volume.

I also optimized large exports with GZIP compression to move ~70MB in ~7 seconds, and set up cron-based pre-processing so heavy datasets are ready before third-party integrations run.

Before that, I worked on a healthcare mobile app with React Native, adding speech-to-text and text-to-speech and coordinating with REST APIs for smooth data exchange.
