At Oak Tree Software Pvt. Ltd., I design, develop, and maintain Ruby on Rails applications, REST APIs, and GraphQL services. I work across performance, security, integrations, and production support.
On Treadmill Doctor, I developed backend services for products, orders, payments, and shipping, and implemented Elasticsearch product search and Redis caching. I also integrated Authorize.Net and PayPal and optimized PostgreSQL queries and indexes.
Across projects including Kadenze, BYJU'S, VIVUP, AVC Wise, and MenuSmile, I’ve worked on learning platforms, employee-benefits workflows, and digital services. I’ve improved API response times by up to 40% through query optimization, indexing, caching, and backend performance improvements.
