System Analyst at SENRI Ltd building client dashboards with Looker Studio and BigQuery SQL.

At SENRI Ltd, I build and maintain interactive client dashboards and reports using Looker Studio. I write BigQuery SQL queries to prepare reporting data, validate dashboard accuracy, and explain metrics and reporting logic to clients.

Previously at Songa Mobility, I managed dashboards and performance reporting, analyzed operational data, and prepared management reports. As a Data and Innovation Intern, I built KPI dashboards and scorecards and automated recurring reports; I also managed social media accounts and created promotional materials using Canva.
