About

A Senior Software Engineer with 5 years of dedicated experience building scalable and efficient backend systems. I specialize in using Java, Kotlin, Spring Boot, and Micronaut to design and implement cloud-native, event-driven architectures. Throughout my career, I have focused on delivering tangible results by tackling complex technical challenges. I am most proud of accomplishments that enhance performance, reliability, and observability. Key Achievements: • Led the modernization of a critical system by transitioning legacy microservices to a robust event-driven architecture. • Drove a 40% reduction in remote troubleshooting time by developing a specialized microservice for soundbox devices at Paytm. • Optimized Kafka pipelines to process over 5 million demand records in under 10 minutes, effectively minimizing consumer lag. • Architected a consolidated, multithreaded backend endpoint that replaced 15+ APIs, significantly reducing latency and complexity. • Improved API responsiveness by 70% and reduced database load by 40% through advanced caching strategies. I am passionate about the entire development lifecycle, from authoring system-level design documents to implementing comprehensive monitoring with tools like Grafana and Prometheus. Specialties: Microservices, Distributed Systems, Event-Driven Design, Kafka, RESTful APIs, Cloud-Native Architecture, System Design & Optimization
