Well structured and Crisply explained the scenarios

Hi Archana, Our recent session on large-scale data modeling for both real-time streaming architecture and batch architecture, using LinkedIn and Amazon as our use cases, was truly enlightening. Your expertise in connecting the dots between various tools and technologies, such as Flink,Spark,NoSQL databases like Cassandra, and batch frameworks, was exceptional. You not only highlighted their specific use cases but also addressed the pain points of legacy systems, including explaining concepts like sharding. Your insights into creating a robust big data streaming and batch architecture, along with building a data model from scratch, were incredibly valuable. This has greatly clarified my understanding of these components and has been instrumental in guiding my decisions for data modeling and designing architectures for systems with large user bases.

I took mentorship from Archarana while preparing for Data Engineering interviews, focusing on Spark concepts, high-level system design, and mock interview practice. Her guidance was incredibly valuable—she brings deep expertise and explains concepts in a way that’s both practical and easy to understand. The documents she shared were well-structured, insightful, and covered nuances that are hard to find online. Her mentorship played a key role in helping me gain confidence and clarity in my preparation
