Hey there! 👋✨

Welcome to my GitHub profile. I’m an HR professional with a business-first mindset, using data, probability, and market logic to make people decisions that directly support business objectives.
I believe HR is most valuable when it acts as a strategic partner, turning workforce insights into actions that drive profitability, efficiency, and measurable growth.

My work integrates HR expertise, data analytics, mathematical reasoning, and market understanding to design solutions that optimize hiring, retention, performance, and workforce cost.
I focus on evidence-based strategies that align people decisions with business priorities, ensuring every HR action delivers clear impact.

Here’s to creating data-driven, business-aligned HR strategies that move companies forward. 🚀
