I build scalable backend services, integrate banking and payment partners such as YesPay, NSDL, Cashgram, QwikCilver, Vouchagram, Indicore, and Zokudo, and implement event-driven solutions with Apache Kafka. I also mentor developers, conduct code reviews, and work closely with Product, QA, DevOps, and business teams to keep releases stable.
