What I'm looking for

I’m looking for an international role where I can build reliable dashboards and automation, translate business needs into technical specs, and partner with stakeholders to improve data accuracy, efficiency, and decision-making.

I’m a data analyst focused on turning business needs into clear technical specifications, with a strong emphasis on data accuracy and consistency. I enjoy building dashboards and automated solutions that help teams make better, faster decisions.

In my most recent role as a Senior Data Analyst, I collaborated on internal projects at a bank—delivering a data dashboard for client insights and driving a metadata management initiative to improve organization and retrieval across departments. I led a project that teams struggled with for over 2 years and finished it in 8 months, creating AS IS/TO BE diagrams and comprehensive implementation documentation. I also supported delivery end-to-end through technical documentation, release documentation, acceptance testing, protocol drafting, and log analysis.

Before that, I worked as a Data Analyst on the transition to a new core banking system (ABS), enabling 75% of reports to run immediately after migration. I analyzed 50 reports within 2 months, traced data sources, and reviewed integrations for continued relevance—while optimizing critical job execution time from 16 hours to 37 minutes by resolving legacy code issues.

I also have experience designing and improving data workflows in complex environments, including optimizing report generation and reducing backlog pressure in a customer loyalty program. I’ve trained users, authored detailed documentation, and supported teams daily through technical support—always aiming to streamline processes through reliable data and practical automation.
