Hi, I’m Isha — a Data Engineer II at Amazon, working with the AWS Supply Chain Automation team, with 7+ years of experience building large-scale data platforms and pipelines. Before Amazon, I worked as a Senior Data Engineer at Visa and as an Azure Data Engineer at Shell, where I gained hands-on experience across large-scale data processing, distributed systems, cloud platforms, and backend engineering. Over the years, I’ve worked extensively with PySpark, Scala, Java, SQL, Kafka, Hadoop, Hive, AWS, Azure, REST APIs, Spring Boot, and data architecture — solving problems ranging from billion-scale data pipelines to real-time analytics and scalable system design. Having recently gone through multiple interview processes for senior data engineering roles across top product and technology companies, I understand how overwhelming interview preparation can be — especially when it comes to DSA, SQL, Spark, system design, data modelling, resume storytelling, and behavioural rounds. Through Topmate, I’d love to help with: • Data Engineering interview preparation • Resume and profile reviews • Mock interviews • SQL, PySpark and DSA preparation • Data Engineering system design & data modelling • Career transitions into product companies • Breaking down your experience into strong interview stories • Guidance for engineers targeting Senior Data Engineer roles My goal is simple: help you prepare with clarity, focus on what actually matters in interviews, and turn your existing experience into a much stronger story. If you're preparing for your next Data Engineering opportunity and need practical guidance from someone who has recently been through the process, feel free to connect with me.
