I am a data and automation professional with experience designing analytics solutions and building automated workflows to support business operations in technology-driven environments. My background combines data analysis, visualization, and process automation, with a strong focus on improving decision-making through reliable, scalable data systems. In my role as a Data Analyst at Better Collective, I used Tableau, SQL, Python, and Excel to analyze marketing campaign performance and downstream conversion metrics. I built dashboards and conducted ad-hoc analyses around campaign KPIs, conversion rates, data quality, and ROI proxies, enabling marketing teams to identify high-performing channels, optimize outreach strategies, and prioritize initiatives based on data. More recently, I have worked in a business-facing and consulting-style role leading automation initiatives and bridging technical and non-technical teams. I enjoy operating at the intersection of analytics, operations, and strategy—building scalable solutions, improving decision-making processes, and delivering measurable impact through cutting-edge technologies.
