Projects
Tour booking system
for travel agency
October 2024 - currently
Design and implementation of a custom tour reservation system for a travel agency in the form of a web application, which will enable management of customer reservations, payment processing, sending of email notifications, as well as production of necessary documents and reports. The project is carried out as an engineering job using Spring Boot, Thymeleaf, HTML/CSS, JavaScript and PostgreSQL technologies.
Movie
recommendation system
