What I'm looking for

I’m seeking a data analyst role where I can apply SQL, Python and BI tools to deliver actionable insights, collaborate with a data-driven team, and expand my analytics and reporting responsibilities in a supportive environment.

I am a dedicated data analyst with formal training in statistics and a Diploma in Data Analytics. I combine academic grounding with professional certification in Human Resource and Customer Relations Management to approach data with a practical, business-focused mindset.

I work with Excel, SQL, Oracle, Power Query, Tableau, Power BI and Python to clean, analyze and visualize complex datasets, and I produce clear data presentations and reports for stakeholders. I also use Zoho People and Zoho CRM for HR/CRM workflows and automated data extraction tools when needed.

My professional experience includes diagnosing customer data in a banking environment, performing product analytics to inform teams, and preparing management reports that highlight trends, patterns and predictions. Prior roles supporting executives and field operations strengthened my documentation, coordination and stakeholder-communication skills.

I deliver actionable insights, prioritize clarity in reporting, and enjoy collaborative problem-solving. I bring resilience, strong interpersonal communication and a willingness to take ownership of data projects that improve decision-making and operational efficiency.
