What I'm looking for

I seek analytic roles where I can build automated dashboards, govern KPIs, improve data quality, and drive product and customer outcomes in a collaborative, growth-oriented team.

I am a growth-minded Data Analyst with over five years of experience in SaaS environments, specializing in SQL, Python, dashboarding, automation, KPI governance, and cross-functional analytics.

At Nextail Labs I led advanced analytics, KPI definitions, model validation, and customer analysis, delivering dashboards and automation that cut prep and validation time dramatically while increasing delivery capacity.

As an entrepreneur I founded and grew a niche travel business, using customer data analysis and targeted marketing to achieve 5× customer growth, over 60% repeat rate, and nearly 4× annual revenue growth.

Earlier, as a Manufacturing Engineer in the U.S., I applied data-driven process optimization to raise precision rates above 95% and cut scrap from 10% to 3%, demonstrating a consistent record of turning analysis into measurable business outcomes.
