Who I am

I'm a Data Analyst and Database Administrator with 6+ years of experience turning messy, complex data into clear, actionable outcomes. My work spans everything from building dashboards and ETL pipelines to managing cloud databases and writing the SQL that actually answers the hard questions.

I've worked across startups and established companies, and what I enjoy most is sitting at the intersection of data and decision-making. Whether it's a C-suite dashboard or a late-night query optimization, I bring the same level of care to the work.

I also use AI as a core part of how I work. Not to replace thinking, but to move faster, explore ideas more deeply, and ship better work. AI handles the repetitive lifting so I can focus on the parts that actually require judgment and experience.

With Claude Code, I can take a project from zero to production. Architecture, backend, database, deployment — I can design and build entire systems safely and securely, end to end.

Certified in AI fluency. Fluent in data. Always learning.
