Kannan Thangaraju

As a data engineer passionate about building scalable and intelligent systems, I specialize in architecting end-to-end data platforms that power high-performance analytics and machine learning applications. With experience spanning fintech, healthtech, and research analytics, I’ve led the design and deployment of large-scale ETL pipelines, real-time data streaming platforms, and search infrastructures in production environments. At Fitch Group, I built a resilient backend powering financial data access with FastAPI, Elasticsearch, PostgreSQL, and AWS-scaling to over 500K API requests/day with <100ms response times. I also architected Airflow-orchestrated Spark workflows processing 10TB+ of data monthly, enabling downstream ML and analytics systems.
