I built full-stack inventory management systems for two retail businesses, including a balut vending business and a gasul (LPG) retail business. They replaced manual spreadsheet tracking with revenue summaries, low-stock monitoring, transaction histories, and CSV export.
As a Freelance Software Developer, I designed relational database schemas and REST API endpoints for products, sales, and inventory, with automatic stock synchronization and a reject-tracking module.
I also built BitterScan, an interactive simulator with English and Cebuano localization, drag-and-drop image upload, and a smartphone simulator interface. It was built with React 19, TypeScript, and Tailwind CSS, and deployed on Vercel.
I built QuizPDF AI, a Flutter app that uses the Groq LLM API to generate quizzes from PDF documents, and shipped it for mobile and web. Before software development, I provided freelance computer repair and technical support, and worked as an Operations & Sales Assistant in a family business.
