What I'm looking for

I’m looking for an analytics consulting role where I can use SQL, Python, and BI tools—powered by AI-assisted workflows—to automate data work and deliver clear, business-ready insights in fast-moving teams.

I’m an Analytics Consultant and Mechatronics Engineer with Google and Microsoft certifications in Data Analytics and ~3 years of experience managing large-scale databases. I specialize in SQL, Python, Power BI, Tableau, and R, and I build analytics that are both technically sound and easy for non-technical stakeholders to act on.

I thrive in consulting environments: I adapt quickly to ambiguity, work across cross-functional teams, and connect data results with clear business narratives. I also leverage AI tools—including Claude Code—to accelerate analysis, automate repetitive tasks, and deliver insights faster.

In my experience, I’ve managed and analyzed large-scale global datasets (including a multi-year COVID-related dataset), automated recurring data cleaning and transformation workflows, and maintained data quality through consistency, normalization, and accuracy. I’ve also built end-to-end BI deliverables, such as a Power BI salary dashboard, designed to provide insight—not just charts.
