What I'm looking for

I’m seeking an SDE, Lead, or Backend role where I can drive scalable system design at a product-led company.

At Quest Global, I migrated a monolith into five microservices using Spring Cloud and Docker, reducing deployment time from two hours to eight minutes with Docker and Kubernetes.

For GE Healthcare’s MRI SWTools serviceability platform, I delivered Java 17 and Spring Boot 3 REST APIs integrated with Angular 15 modules for calibration, license management, and remote diagnostics. I also implemented JWT-based authentication and Kafka event-driven flows.

At Birlasoft Limited, I developed Spring Boot APIs and responsive Angular applications for Al-Rasheed Cement’s order-fulfilment platform, connecting supplier, consumer, and transport workflows. I also enhanced Model N’s Price Administration and Rebate modules.

At Synchronoss Technologies, I worked on wireless and wireline order gateway systems, including a Java-based order engine and XML Schematron validation. I also designed Oracle schemas and optimized queries.
