My Projects
Here are some of the projects I've worked on. Each project represents a unique challenge and solution.
Sales Forecasting System Using Deep Learning
This project developed a sales forecasting system using deep learning, specifically the Long Short-Term Memory (LSTM) model. The system outperformed traditional machine learning methods in prediction accuracy. Integrated with a web application, it enables retailers to improve sales planning, inventory management, and future marketing strategies. This project was selected for presentation at NCCIT 2025, a national-level IT conference in Thailand. (Page331-336)
Personal Debt Management System - DeptX
Developed a full-stack personal debt management system using Next.js 15 and PostgreSQL to help users efficiently track and manage their personal debts. This system was designed to solve traditional debt management problems by providing systematic tracking and financial planning capabilities.
