I analyzed 2023 job-posting data with PostgreSQL to surface top-paying roles, in-demand skills, and skills with high earning potential. I also built a Power BI dashboard exploring 2024 data science job postings, including salaries, locations, job titles, and remote-work trends.

As an Excel Dashboard & Reporting Specialist on independent contracts, I built a school report card system and church financial and attendance dashboards, with validation to support accurate reporting. Earlier, at Sky-Net Technology Institute / IT Support Organization, I cleaned and visualized sales and operational data and developed spreadsheet solutions for JuliusBerger.
