Hi, I'm Dipankar Sethi. I am currently a Cloud & AI Consultant at Microsoft, specializing in building robust backend systems and scalable microservices. My daily engineering involves working deep in the backend ecosystem, leveraging Java, Spring Boot, Python, and FastAPI, alongside tools like Kafka, Redis, and Docker. Before joining Microsoft, I built microservices from the absolute ground up for a fast-paced startup, which gave me a highly practical perspective on how to architect real-world, secure, and highly available applications. I am deeply passionate about system architecture and share my learnings by posting daily system design videos on YouTube and Instagram. On the problem-solving front, I am a hardcore competitive programming enthusiast. I have maintained a 300-day streak on LeetCode with over 1150+ problems solved and an 1800+ rating. Having navigated the entire spectrum from being a Smart India Hackathon (SIH) finalist to returning as an SIH mentor- I know what it takes to break into top-tier tech companies.
