Software Development Engineer (Backend) building secure Java/Python REST APIs and microservices.
IndiaWhat I'm looking for
I’m a Software Development Engineer (Backend) focused on building reliable, secure RESTful services for real-world products—especially user onboarding and authentication workflows. At Signzy, I developed and maintained core REST APIs for a banking customer onboarding application, integrated third-party identity/document verification, and supported internal admin tooling for review and status updates.
I also enjoy tightening quality and resilience in production. From resolving issues like expired onboarding links and missing email/SMS notifications to delivering Java backend modules at Accenture that contributed to a 20% improvement in user satisfaction, I bring strong OOP and microservices-minded engineering to every release. In my Expense Tracker project, I built high-performance REST APIs with Spring Security and JWT stateless authorization, applied clean DTO/exception-handling patterns, and validated behavior with JUnit 5 and Mockito.
