Hi, I'm Harisankar
Data Engineer & Business Intelligence Specialist
I build scalable data pipelines, intuitive dashboards, and analytics solutions that turn raw data into business impact. With 5+ years of experience in software and data engineering, I'm passionate about creating systems that drive data-driven decision making.
About Me
I'm currently pursuing my Master's degree in Information Management at the University of Illinois Urbana-Champaign, building on my 5+ years of experience in software and data engineering.
My passion lies in creating scalable analytics solutions and machine learning systems that transform raw data into actionable business insights. I thrive on solving complex data challenges and building systems that can handle massive scale while maintaining reliability and performance.
When I'm not working with data pipelines or building dashboards, I enjoy mentoring junior engineers and staying up-to-date with the latest developments in data engineering and machine learning technologies.
