About Me

I'm Saksham — a business and data analyst with an MSc in Business Analytics from University College Cork (Business Merit Scholarship). I build dashboards, analyse data, and turn complex findings into actions that improve how organisations operate.

At Centra (Ireland's largest convenience chain), I improved inventory accuracy by 15% through data-informed stock monitoring. At ValueMax Advisors, I built Power BI dashboards for senior leadership, used SQL and Python to find process bottlenecks (12% cycle time improvement), and automated reporting that cut manual effort by 25%.

At the Indian Space Association, I created analytics dashboards visualising investment trends for executives and managed data operations for an 800+ participant event tracking 80+ sponsors.

My MSc dissertation involved building a supplier risk prediction platform using Python, Snowflake, and Tableau — achieving 90% classification accuracy.

Based in Cork, Ireland with full-time work authorisation (Stamp 1G). Open to roles in Business Analysis, Data Analytics, BI Development, and Operations Analytics across Ireland.
