At Multiplier, I designed and developed a greenfield Kotlin/Spring Boot workshift configuration service, from HLD/LLD and database design through GraphQL/gRPC APIs and production deployment.
I optimized timesheet schedulers with two-step pagination and batch processing, reducing memory use from 500MB+ to 30MB and eliminating production OOM failures across 540K+ records. I also replaced 773 sequential requests with one bulk gRPC call, removing a roughly 77-second bottleneck from a production contract report.
As a Software Engineer Intern at Multiplier, I delivered backend features for AOR timesheets and improved test coverage from 6% to over 90% at module level. I also built a full-stack e-commerce project with the MERN stack, including role-based authentication and an admin dashboard.
