Pranav Mule

Software Engineer at Tata Consultancy Services (2024-03 – 2026-05)

Developed and maintained Java Spring Boot backend services for core BFSI banking workflows — designed RESTful API endpoints, service-layer business logic, and data-access layers handling critical financial operations across multiple production modules.
Implemented JWT-based authentication and role-based authorization across customer, operations, and admin roles — securing API endpoints and enforcing access control across enterprise banking systems.
Resolved Service Requests (SRs) and Change Requests (CRs) by performing systematic Java debugging — traced execution flows, analyzed stack traces, identified root fixes, and consistently delivered within SLA turnaround commitments in a 24x7 environment.
Performed structured Root Cause Analysis (RCA) for 15+ high-severity production incidents — including API failures, Spring Boot service crashes, SQL deadlocks, and data inconsistencies — implementing preventive fixes and maintaining zero critical SLA breaches.
Optimized MySQL query performance and database schemas for financial reporting and validation pipelines — rewrote N+1 queries, introduced composite indexes, and improved query execution speed for high-volume banking data operations.
Optimized React.js frontend across 2+ enterprise banking modules via code-splitting, lazy loading, and API batching — achieving ~50% reduction in page load times; containerized applications with Docker and maintained CI/CD pipelines across dev, QA, and production.
