I'm Ashwani Kumar Patel, currently a Backend Engineer at Walmart. With over 5.5 years of experience, I specialize in Java, Spring Boot, and building scalable systems. I transitioned from a non-IT background, cracked GATE, and completed my M.Tech from IIT. Previously at MoneyTap, I built FreoPay from scratch, handling millions of transactions. I’m here to mentor on backend development, system design, career transitions, and interview prep.
