Developed a seamless event ticket booking system that guides users directly from the event detail page into a structured registration and payment flow. The feature was designed to provide a frictionless booking experience while fully automating ticket generation, invoicing, and customer communication.

The booking form includes robust client-side validation powered by Yup, ensuring clean and reliable user input before submission. For payment processing, the integration of the PayPal API enables secure online transactions with real-time payment confirmation.

Once a booking is successfully completed, the system automatically generates a digital ticket and invoice PDF using renderPDF, creating professional, downloadable documents tailored to each transaction. To complete the customer journey, Nodemailer is used to send automated confirmation emails containing a unique access link to the booked ticket and, if applicable, the invoice.

This feature combines payment automation, document generation, and transactional email workflows into a streamlined end-to-end booking experience that reduces manual administration while improving usability for event participants.

Developed an interactive self-assessment tool that allows users to independently and free of charge evaluate whether they show potential indicators of high sensitivity. The feature was designed to create a low-barrier entry point for users seeking initial orientation, while also providing meaningful results that can serve as a foundation for further reflection or professional discussion.

Built with JavaScript and dynamic rendering, the assessment delivers a responsive, step-by-step questionnaire experience that adapts smoothly throughout the user journey. After completion, the system automatically processes the responses and generates a structured PDF evaluation report using PDF rendering, presenting the results in a clear and accessible format.

The generated report is not intended as a clinical diagnosis, but rather as a valuable indicator and conversation starter—helping users better understand their traits and providing a practical basis for discussions with coaches, therapists, or other professionals.

This feature combines interactive frontend logic, automated report generation, and purposeful user guidance into a digital self-service experience that delivers real value while remaining simple, accessible, and informative.

Designed and implemented a robust order processing and payment management system focused on reliability, clean data handling, and seamless user experience throughout the full booking lifecycle.

The checkout flow integrates the PayPal API for secure payment processing, while Strapi CMS is used to manage transactional data and generate unique ticket records for each completed order. Following a successful purchase, the system automatically creates professional ticket and invoice PDFs through a dedicated PDF rendering service, enabling fully automated digital fulfillment.

A key technical challenge of this feature was handling interrupted or abandoned order processes. Users can cancel or leave the booking flow at different stages, which directly impacts already initiated ticket creation, user assignments, and payment-related records. To address this, a comprehensive backend logic was implemented to manage transactional dependencies and state changes across the system.

This includes automated cleanup processes that prevent unnecessary data persistence, remove orphaned records, and ensure that tickets, assignments, and payment-related datasets remain consistent and synchronized. The result is a scalable order architecture that not only supports smooth conversions, but also maintains high data integrity, system efficiency, and compliance with clean data management principles.
