With over a 5+ of experience in software development and engineering, I specialize in building scalable, distributed systems and solving complex technical challenges. Throughout my career, I’ve had the privilege of working at some of the most influential technology companies, including Arcesium India and Expedia Group. Currently, I am working in the Expedia group as a SDE II Backend Engineer, I lead efforts in developing and optimizing large-scale systems, ensuring reliability, performance, and scalability. During my time at Expedia, I had a chance to build Traveler-Api Service from scratch which is serving 5 million+ lodging booking requests per week. I had a cucumber testing framework that is robust extensible and widely used in Expedia now. I thrive on collaborating with cross-functional teams, mentoring fellow engineers, and continuously refining systems to meet user needs and business goals. My expertise extends to designing architectures that align with industry-leading standards while maintaining high system availability.I developed backend services, created APIs, and implemented CI/CD pipelines to improve deployment efficiency. During my tenure at Arcesium, I honed expertise in both SQL and NoSQL databases, leveraging these skills to deliver robust, high-performance solutions. As part of a leading fintech organization, I played a pivotal role in managing and enhancing the FUMA platform, a core system for comprehensive fund management. My responsibilities included architecting scalable database solutions, optimizing complex queries, and ensuring seamless data flow to support critical financial operations.Earlier in my career, I worked as a TA in Coding Ninjas which is an online teaching platform in Delhi India. Passionate about continuous learning, mentoring, and working on complex engineering problems, I aim to create meaningful solutions that drive growth, efficiency, and user satisfaction.
