About

I’m a Senior Software Engineer with ~4 years of experience building and scaling high-performance backend systems. I’ve worked on large-scale systems where reliability, performance, and clean architecture matter, managing critical Spring WebFlux services, designing event-driven workflows with Kafka, and optimizing APIs that serve real users at scale. What I focus on: • Scalable backend architecture & microservices • Reactive systems using Spring WebFlux • System design, performance optimization & observability • Cloud-native development on AWS (S3, ECS) • Writing clean, testable code with TDD & CI/CD Tech stack: Java, Spring Boot, Spring WebFlux, Kafka, Microservices, JPA, Hibernate, Spring Security, AWS (S3, ECS), Docker, Jenkins, MongoDB, SQL, Grafana, Prometheus, New Relic, System Design (HLD/LLD), Multithreading, TDD, Agile. If you’re interested in: ✔ Backend engineering ✔ Java & Microservices ✔ System design discussions ✔ Real-world production learnings Feel free to connect or follow.

Owned and managed 5+ critical backend microservices built with Spring WebFlux, maintaining 99.9% uptime and meeting strict client SLAs.
Designed and implemented reactive APIs, improving system performance by ~40% and significantly reducing response times under high load.
Refactored synchronous APIs (~30s latency) into asynchronous, event-driven workflows, bringing response times down to ~6s.
Built event-driven architecture using Kafka to process and consume high-volume events across services.
Led Java upgrades (8 → 17), modernized Spring Boot & Gradle setup, and resolved long-standing code smells and complexity issues.
Improved test coverage from ~50% to ~95% using JUnit & Mockito, strengthening CI/CD pipeline reliability.
Mentored junior engineers, conducted code reviews, and aligned technical decisions with business goals.
