About

As a Senior Software Development Engineer with over six years of experience in backend, I specialize in building high-performance, scalable microservices and optimizing system performance. Currently at Disney+ Hotstar, I have successfully managed high-traffic events, like the Cricket World Cup live stream with 22 million concurrent users, and implemented crucial service optimizations. My background includes significant roles at Amazon and Disney+ Hotstar, where I contributed to pivotal projects such as the Buy Online Pickup In-store (BOPIS) experience, user management systems and A/B Tesing platform. I am skilled in Java, Spring, Javascript, distributed systems, and have hands-on experience with a wide range of technologies such as AWS DynamoDB, SQL for databases, Kafka, SQS for queues/event driven architecture and Redis for caching. Passionate about continuous learning and improvement, I actively participate in debugging, performance tuning, and collaborating with cross-functional teams to deliver innovative solutions. Let’s connect if you’re looking for a dedicated and skilled software engineer who can drive your projects to success.
