Analyst. Storyteller.
Problem Solver.

I'm a graduate student earning my M.S. in Data Analytics at Clark University (GPA 3.85) and a Data Analytics professional with roots in both business and engineering. My journey spans SaaS, Healthcare, HR, Hospitality, and Consumer Analytics — and one common thread runs through all of it: making data usable for the people who need it most.

At Vosyn, I built Power BI dashboards and predictive pricing models. At Vistaar Digital, I automated reporting pipelines that saved 13+ hours per cycle. I'm also a co-author on a published research paper about AI-enabled learning systems (SMARTSETGO).

What sets me apart isn't just technical fluency — it's the ability to sit across from a business stakeholder, understand their real question, and come back with a clear, compelling answer built from data.

My mission is to advocate for scalable, data-driven solutions that don't just report the past — they illuminate the path forward.
