What I'm looking for

I'm looking to apply SQL, data validation, analytics, and implementation support to translate business questions into reliable decision-support tools while collaborating across teams and improving operational processes.

I've built SQL, PostgreSQL, Tableau, and interactive data applications that turn complex job-market data into validated decision-support tools. My Global AI Jobs Market Analysis cleaned 15,000 unique postings and normalized 59,893 job-skill combinations for an interactive Tableau dashboard.

For the Global AI Salary Opportunity Command Center, I translated analytical requirements into filters, salary-quartile logic, market rankings, skill-combination analysis, recommendations, and a 3D opportunity map. I also used OpenAI Codex for implementation, debugging, refactoring, and interface testing while validating metrics against source data.

Alongside my Business Analytics studies at San José State University, I bring 10 years of retail management experience from Banana Republic and Uniqlo. I've improved workforce allocation, reporting efficiency, customer outcomes, revenue, and cross-functional operations through Excel-based analysis, process improvement, and clear communication.
