I’m a Backend Software Engineer with 1.5+ years of experience building distributed, high-throughput Java applications. I focus on secure API design and production reliability, turning complex requirements into maintainable services that teams can trust.

At Pelatro Solutions, I integrated OAuth2/JWT authentication for secure REST APIs across CRM services, and improved compatibility by enhancing Netty server behavior for CORS (Cross-Origin Resource Sharing) and configurable session timeouts. I also led performance-focused work—implementing multi-threaded report generation and archiving with Java Executors—cutting processing time by 40% while preventing server timeouts.

I strengthen reliability with automation and scalable data processing. I enhanced scheduler-based automation for recurring report jobs using Java Timer and ScheduledExecutorService to reduce manual triggers, and I engineered the LMS Subscriber Dump Report using MapReduce to process 1M+ records per batch with optimized query performance.

I also enjoy shipping practical, product-aligned improvements: I enabled automated campaign asset creation by integrating GenAI APIs, cutting production time in half, and developed configurable game definitions that support gamified campaigns for offer redemption and loyalty rewards. I back it all with engineering discipline—integrating PMD for static analysis and JaCoCo for test coverage reporting as part of CI/CD pipelines—and I’ve participated in production debugging, root-cause analysis, and deployment optimization. I’m energized by my Rookie Award at Pelatro for outstanding performance with less than one year of experience.
