Data Analyst with 5+ years of experience handling business-critical operational data in SLA-driven environments, particularly within the Travel Tech industry.
I specialize in data accuracy, validation, operational reporting, and transforming raw data into actionable insights for business and operational decision-making.

I transitioned from Data Operations into Data Analytics through project-based learning, hands-on analytics projects, and real-world operational data system implementation.
I focus on how data flows, where errors occur, and how insights support decisions, not just on tools or dashboards.
