What I'm looking for

I'm looking to keep growing in data analytics, using SQL, Python, Tableau, and AI-enabled tools to answer good questions, improve decisions, and communicate evidence-based insights.

At Analytical Factor, I analyze large-scale demand and sales time-series data to improve forecast accuracy. I've improved WMAPE by about 10% on selected forecast streams through segmentation, method optimization, seasonality adjustments, and outlier handling.

I evaluate forecast performance across products, regions, and time periods, present results in weekly client calls, and create implementation guides that standardize forecast configuration. I also onboard and train new analysts on analytical workflows and team best practices.

Before moving into data analytics, I built research tracking and reporting workflows at NeuroKaire and supported assay development and NGS workflows at AID Genomics. I bring an evidence-first mindset to SQL, Python, Tableau, statistical analysis, and data storytelling, and I'm curious about how AI is changing the way we work with data.
