Bitwise Solutions Pvt. Ltd.

Modernized a legacy stack to Spring Boot 3.x + Java 21; restructured Maven build pipeline and separated domain/service/controller layers — improved release cadence by 60% and cut regression rate by 25%. Split tightly-coupled code into clearer boundaries (domain/models, service layer, controllers), enabling parallel workstreams and accelerating delivery by 30% with 25% fewer regressions. Integrated IDP authentication for secure login and password-reset flows and standardized authorization handling across modules. Hardened payment/earnings/claim workflows by strengthening validation, status transitions, and API contract consistency—cutting payment-related defects by 25%. Stabilized external integrations (invoice/program callouts) by adding resilient error handling, a timeout/retry strategy, and diagnostic logging—reducing upstream-driven failures by 30%. Designed and enhanced materialized views + stored procedure-based queries in Oracle/PostgreSQL to accelerate dashboard/report reads, boosting query performance by 35%. Served as a go-to engineer during high-severity incidents: led RCA sessions, unblocked junior engineers with debugging playbooks, and ensured regression-safe releases through CI/CD.
