Full-Stack Developer Intern
School Division Office City of Baliwag
Oct 2025 — Feb 2026 · 600 hours- Delivered MSSS, a full-stack procurement web app, across 600 hours covering the full SDLC from schema design to deployment. It replaced a manual, paper-based process for 3 user roles across the division.
- Built a secure REST API with Node.js, Express, and PostgreSQL, using JWT authentication and role-based access control so each of the 3 roles only reaches its permitted workflows.
- Integrated Nodemailer email notifications, migrated file storage from Azure Blob to Supabase, and built a Google Apps Script pipeline that validates incoming enrollment emails and extracts Excel data into a central Google Sheets report, removing manual file-sharing and data entry.
