About

I’m a Software Engineer with over 8 years of experience building robust, scalable backend systems and microservices using Java, Python, Spring Boot, and Spring Cloud. My work spans high-throughput data processing, reactive programming with Spring WebFlux, and designing RESTful APIs and event-driven architectures with Kafka. I’ve contributed to key modernization efforts, including migrating legacy services to reactive architecture improving throughput, responsiveness, and scalability. I also designed and implemented an auto-remediation solution that eliminated daily manual intervention, significantly reducing on-call overhead. Earlier in my career, I helped build a product from the ground up at a startup, developing core backend services, optimizing APIs to handle 200K+ requests per second, and contributing across domains like authentication, search, communication, and payments. I'm passionate about building clean, efficient, and reliable systems and I actively sharpen my skills in Data Structures and Algorithms, believing strong fundamentals lead to better system design and problem solving. I enjoy tackling complex backend challenges and helping teams deliver software that scales.
