What I'm looking for

I’m looking for a data analytics role where I can build impactful dashboards, automate reporting, and turn insights into measurable business improvements—preferably with global remote flexibility and strong cross-functional collaboration.

I’m an accomplished Data Analyst with 10+ years of experience in technology-driven environments, specialising in data analytics, business intelligence, and process optimisation. I’m expert in SQL, Python, Excel, Power BI, and Tableau, with a strong foundation in data modelling, ETL processes, and dashboard development. I’m recognised for improving reporting efficiency by up to 40% and reducing operational bottlenecks through automation and advanced analytics.

In my current role, I analyse HR and recruitment data for 5,000+ candidates, delivering insights that improved hiring efficiency by 15% and reduced time-to-fill by 10 days. I built and deployed 5 interactive Power BI dashboards that reduced reporting time by 40%, and I spearheaded SQL/BI automation that cut manual effort by 50% while improving data accuracy. Previously, I prepared senior management performance reporting, supported migrations with 99% data accuracy, and drove automation opportunities that saved ~8 hours per week—always aligning stakeholders on data-driven decisions.
