Work Experience

Java Full stack developer

Bytestrone (P) Ltd

Aug 2023 - Present

Leaded a team of developers on backend delivery: assigning tasks, conducting code reviews, setting technical direction, and ensuring on-time delivery across multiple client projects. Conducted Java and Spring Boot training for an intern batch of 10+, covering core Java, OOP, design patterns, and Spring Boot fundamentals; currently mentoring junior engineers on the team. Driving an internal engineering initiative to standardise backend architecture patterns and elevate overall team engineering quality. Identified and resolved a critical performance bottleneck — refactored ~18 sequential external API calls to parallel execution using CompletableFuture, reducing response time from ~120 s to ~40 s (66% improvement). Load-tested the solution with JMeter before production rollout; zero regressions under concurrent traffic; maintained full backward compatibility. Architected fault-tolerant Apache Camel routes integrating LexisNexis APIs for real-time risk evaluation and transaction monitoring. Implemented retry and dead-letter channel recovery; isolated fraud workflows from the core payment system to contain failure blast-radius. Led end-to-end backend development: entity model, service layer, REST API contracts; for a multi-role fleet inspection system supporting inspector, auditor, and admin roles. Implemented JWT-based RBAC using Spring Security; built backend PDF compliance reporting system, eliminating paper-based workflows across fleet operations. Provided ongoing technical guidance to team members and coached developers on API design and security best practices.
