What I'm looking for

I am seeking remote-first opportunities that value high-level technical expertise and strategic thinking. Having built a specialized profile in Data Analytics and Marketing, I am looking to bring innovation and efficiency to a North American team that appreciates global talent and rewards impactful results.

I am a committed data analyst with a strong marketing background who improves business processes through practical data work and dashboarding. I combine Excel, SQL and Power BI skills with marketing knowledge to turn data into actionable recommendations.

I led a portfolio project analyzing Netflix streaming performance across pricing and engagement metrics, building SQL views, cleaning and transforming data, and delivering Power BI dashboards that highlighted trends and anomalies for marketing optimization.

In operational roles I redesigned Excel workflows, implemented automated registration and tracking systems, used HubSpot for outreach, and supported brand restructuring—consistently improving efficiency and data consistency across teams.
