Hi, I’m Aryan — currently working as an SDE II at Morgan Stanley, previously with NPCI (UPI Design & Development) where I helped build scalable fintech systems powering India’s digital payment infrastructure. I specialize in Java, Spring Boot, Microservices, Kafka, Redis, and Cassandra, with a growing focus on applying AI/ML to enhance backend performance and automation. On Topmate, I love sharing insights about system design, backend architecture, fintech scalability, and career growth in software engineering. Whether you're preparing for interviews or building real-world projects, I’m here to help you level up 🚀
