At PT Nusa Digital Teknologi, I developed and maintained internal web features using React, TypeScript, Node.js, and PostgreSQL. I also built and consumed REST API endpoints for user, product, and reporting modules.
I fixed production bugs, improved form validation, and refactored reusable UI components to reduce duplicated code. I wrote SQL queries for operational reports and assisted with database schema updates under senior engineer review.
On TaskFlow, I built a full-stack task management application with authentication, project boards, task status, due dates, and simple role-based access. I also created SpendTrack, a responsive expense tracking app with category filters, monthly summaries, and server-side API routes.
