    Professional Summary

    Full-stack software engineer with 7+ years at Collier County Public Schools, currently leading development and technical direction for Origin, a district-wide internal application. Most projects begin with understanding how a department works and finding a simpler way to support it with software. Daily work centers on PHP, Symfony, JavaScript, SQL Server, and PostgreSQL. Grinkt.com extends that experience through independent product development with TypeScript, React, Next.js, Prisma, and Vercel.
