About Harish Nandanan

I am a Senior Software Engineering Manager with over 16 years of experience in Big Data platforms and backend systems. Currently, I lead the Big Data platform for Roku, managing petabytes of data. My responsibilities include overseeing a global, cross-functional team across the US, UK, India, and Argentina. During my tenure, I successfully expanded our operations to the UK, India and Argentina. In my role, I spearheaded Roku\'s transition to a multicloud strategy by migrating our Big Data platform from AWS to GCP. During the challenging post-COVID macroeconomic conditions, my team and I identified and implemented cost-saving measures through re-architecture and optimization, reducing cloud costs by millions of dollars. Before taking on a leadership role, I was one of the earliest members of Roku’s current Big Data Platform Team. I was actively involved in the design, architecture, end-to-end development, and support of the platform, scaling it to meet Roku\'s petabyte-scale Big Data requirements. I designed, developed, and supported critical systems such as Roku Device Log Ingestion, Device Log Search, and the Data Monitoring Framework using open-source technologies like Spark, Hadoop, Elasticsearch, Java, Scala, Python, Hive, and more. Previously, I worked with Symantec\'s Analytics Data platform, an AWS-based ETL platform that scaled to petabytes of security data. There, I architected and developed a Python-based Big Data Application Execution Framework supporting applications such as Spark, Hive, HBase, and Oozie, and developed real-time data processing pipelines using Apache Storm and Kafka. Before Symantec, I contributed to Actian’s Cloud Management Console and Matrix Management Consoles, where I developed Java Web Services for a PaaS provisioning system for dynamic data analytics databases and tools on multiple clouds, and helped create a system to manage and monitor Actian’s Matrix Database, the basis of Amazon Redshift, a petabyte-scale distributed data warehouse. Earlier in my career, I worked for Apple through Infosys, developing Hadoop MapReduce jobs for Apple iCloud and working on a Data Validation Framework for Apple\'s data reporting system. Before transitioning into Big Data and cloud systems, I honed my software engineering skills by designing and developing core Java applications at Apple and Bank of America. This experience included significant work on developing core Java applications and web services.
