My Work Experience

Where I've interned and worked during my career.

SaaS Company | Jun 2022 - Present

Data Analyst

In my current role, I analyze company data using tools such as Excel, Tableau, SQL, and Python to provide insights on my team's performance, as well as process relevant financial and business-related data for stakeholders. This role allowed me to greatly improve my competencies in skills such as data modeling, trend analysis, and predictive analytics. Not only that, but I also conducted market research, which helped me gain expertise in market segmentation, competitive analysis, and customer profiling. Additionally, evaluating campaign performance allowed me to excel in ROI analysis, A/B testing, and performance optimization. One of my favorite parts of the job was automating reports and monitoring KPIs and business metrics such as ROI, customer acquisition, and retention. It was thrilling to see how small changes to our marketing strategies could have a significant impact on these metrics and help us achieve measurable business goals. To analyze large datasets, I used a variety of tools, including Python, SQL, and Tableau. These allowed me to extract, transform, and analyze data to provide data-driven insights to my stakeholders, such as the marketing team, cross-functional teams, and upper management. Through my contributions, I was able to help Kaverto Media increase revenue and market share.
