At Third Wave Coffee, I work across backend-heavy production systems, including an ordering flow that supports approximately 18K orders a day. I use Kafka for asynchronous payment processing and connect orders to the POS system.
I integrated Cashfree payments and built the user-auth service with OTP and WhatsApp login, owning session tokens, refresh, and invalidation. I also fixed an order-service thread leak, reducing memory usage by approximately 50%.
I’ve also built Jenkins CI/CD pipelines and delivery aggregator integrations, and contributed to the low-level design of seven core services. Earlier, as a Full Stack Intern at Third Wave Coffee, I developed a real-time order management dashboard using React.js, Redux Toolkit, Spring Boot, and Kafka.
