Ayush Singh

Java Backend Engineer with 2+ years building production Spring Boot services for an insurance platform used by 500K+ policyholders. Own backend delivery end-to-end – REST API design, Spring Data JPA/Hibernate data layer, and UAT-to-production release – across Oracle and PostgreSQL. Reduced batch query execution time by 70% and raised unit test coverage from 4% to 70%, cutting regression risk across releases.

Associate Software Engineer – Java Backend at Indus Net Technologies (2024-06 – Present)

• Shipped the Self & Spouse Insurance Policy Module for the SahajBeema platform (with Niva Bupa) end-to-end, by designing and owning independently-deployable Spring Boot services, REST APIs, and Hibernate/JPA data models for insurer-specific integration workflows from build through UAT.
• Delivered a zero-downtime Oracle data migration affecting 5 lakh+ user records, by writing and validating production migration queries for Niva Bupa’s master configuration update.
• Prevented a production outage during a third-party insurer (Bajaj) domain migration, by implementing exception-handled fallback logic for their API endpoints ahead of the cutover.
• Cut batch-processing query execution time by 70% and eliminated recurring deadlocks, by rewriting high-volume Oracle queries using SQL MERGE statements and query-plan optimization.
• Reduced maintainability issues from 370 to 165 and raised unit test coverage from 4% to 70%, by leading a SonarQube clean-code initiative using JUnit 5 and Mockito integrated into the CI pipeline.
• Improved eKYC verification reliability for HDFC’s secondary policy flow, by migrating the third-party API integration from Karza to Surepass with backward-compatible error handling.
• Streamlined the insurance admin portal’s usability and access control, by designing pagination, filtering, role-based authentication/authorization, and SQL-driven reporting across insurer-wise policy and claims dashboards.
• Reduced release friction for the QA team, by owning UAT deployments across both the React frontend and back-end services using PuTTY and WinSCP for Linux server access and build deployment.
• Improved production reliability, by installing and maintaining scheduled cronjobs, debugging failing API endpoints, and proactively detecting and triaging production issues via server log analysis.
