What I'm looking for

I am looking for a challenging role where I can lead analytics and automation initiatives, drive measurable business impact, and grow into strategic data leadership.

I am a Business Analyst with over five years of experience delivering data automation, business intelligence, and predictive analytics solutions across pharmaceutical, banking, and retail sectors.

I design and implement scalable data workflows using Salesforce, GCP, Azure, Looker and Power Platform to optimize reporting and support decision-making. I led an automated customer journey that reactivated 5% of inactive clients (~30,000) and generated over $100,000 in three months.

I co-founded a Data department, led Data Governance and Quality initiatives, and built a Power Apps information-asset application to centralize critical data. I also introduced mentoring and adoption programs to foster a data-driven culture.

I apply agile methodologies and experiment-driven approaches (A/B and multivariate testing) to measure incremental impact, reduce manual effort, and scale analytics—seeking roles where I can lead analytical strategies that deliver tangible business value.
