What I'm looking for

I am looking for a role that allows me to leverage my analytical skills in a collaborative environment, focusing on data-driven decision-making and continuous learning.

I am a detail-oriented and result-driven Data Analyst with one year of experience in leveraging data analysis tools and techniques to deliver actionable insights. My proficiency in SQL, Python, Excel, and data visualization tools such as Power BI and Looker Studio enables me to contribute effectively to data-driven decision-making and business growth.

In my role at Tylink Group, I collected and processed large amounts of customer data, analyzed it to identify patterns and trends, and developed predictive models to optimize business processes. I also created reports and visualizations to present analytical results to the management team. My internship at Practical Action further honed my skills in data collection, hypothesis testing, and process optimization, allowing me to apply my knowledge to solve practical problems and improve business processes.
