About

The Event Registration Web Application is a secure, enterprise-grade platform developed for the Austrian Government to streamline and modernize the registration process for journalists attending official government events such as press conferences, briefings, ministerial announcements, and public communications. This comprehensive full-stack solution replaces manual registration workflows with an efficient, secure digital system that meets stringent government security standards while providing an exceptional user experience.

The platform serves two distinct user groups: journalists who register for events and manage their professional profiles, and government administrators who review, approve, and manage registrations through a sophisticated administrative dashboard. The system supports German and English languages to accommodate Austria's diverse domestic and international media landscape, ensuring accessibility for press representatives from around the world.

As the sole developer on this project, I was responsible for the complete solution lifecycle including requirements analysis with government stakeholders, system architecture design, frontend and backend development, database schema design, security implementation, testing, and deployment. This project demonstrates my ability to independently deliver government-grade secure applications that handle sensitive data while meeting complex business requirements.

Key Features

Journalist User Features

Seamless Event Registration

Journalists can browse upcoming government events, view detailed information including date, time, location, and specific registration requirements, and submit registration requests through dynamically generated forms. The registration process is streamlined and intuitive, with clear status tracking showing whether registrations are pending, approved, or declined.

Multi-Language Interface

The entire platform supports both German and English languages, implemented using Vue i18n. All UI elements, form labels, validation messages, error notifications, and help text are fully translated. Users can seamlessly switch between languages, with their preference persisted across sessions for consistent experience.

Profile Management

Registered journalists can manage their professional profiles including contact details, media organization affiliation, accreditation status, and communication preferences. Administrators control which fields journalists can edit after initial registration, preventing unauthorized changes to verified information while allowing updates to non-critical data.

Real-Time Status Tracking

Journalists receive immediate feedback on their registration submissions and can track the status of all their requests through a personal dashboard. Email notifications keep them informed of status changes, approvals, and any additional information required.

Administrator Features

Comprehensive Admin Dashboard

The administrative interface provides government staff with a centralized hub for managing all journalist registrations. The dashboard displays pending, approved, and declined registrations in responsive data tables that dynamically render columns based on the data structure returned from APIs, adapting seamlessly to different screen sizes.

Multi-Stage Registration Workflow

Administrators can review registration details and take one of three actions: accept the registration (sending confirmation to the journalist), decline with an optional reason (notifying the journalist), or forward to another department for additional verification. This flexible workflow supports complex approval processes while maintaining a complete audit trail.

Dynamic Form Builder

One of the most innovative features allows administrators to create custom event registration forms without writing code. Through an intuitive interface, admins can add various field types (text inputs, dropdowns, checkboxes, date pickers, file uploads), configure validation rules, set required/optional status, and specify labels in both German and English. The form builder generates JSON schema configurations that Vue.js dynamically renders for end users.

User Permission Management

Administrators can control which profile fields journalists are allowed to edit, with granular settings for each data field. This ensures data integrity for verified information while allowing flexibility for non-critical updates.

Technical Challenges & Solutions

Challenge 1: Government-Grade Security Implementation

The Problem: Government applications handling journalist personal data and event access must meet stringent security standards. Traditional authentication approaches were insufficient, and the system needed to prevent common vulnerabilities while remaining user-friendly.

The Solution: Implemented a comprehensive security architecture using Spring Security with JWT-based stateless authentication. Passwords are hashed using bcrypt algorithm before storage, ensuring credentials remain secure even if the database is compromised. The RBAC system enforces authorization at both API and UI levels, with Spring Security's method-level annotations preventing unauthorized access to sensitive endpoints. All communications use HTTPS/SSL, with CORS, CSRF protection, and input validation preventing common attack vectors.

Challenge 2: Multi-Language Dynamic Content

The Problem: The platform needed to support German and English throughout the entire application, including dynamic content created by administrators (event descriptions, form fields). Static translation files would be impossible to maintain for administrator-generated content.

The Solution: Implemented Vue i18n for static UI translations with comprehensive language files covering all interface elements. For dynamic content, designed the database schema and API responses to support multi-language fields, allowing administrators to enter content in both languages during creation. The frontend language switcher dynamically updates all content including form fields, validation messages, and event details.

Challenge 3: Dynamic Form Generation and Rendering

The Problem: Different government events have varying registration requirements. Creating custom forms for each event would require developer involvement, creating bottlenecks and delays.

The Solution: Built a sophisticated dynamic form builder that generates JSON schema representations of form configurations. The admin interface allows non-technical staff to create custom forms with various field types, validation rules, and multi-language labels. The Vue.js frontend dynamically parses these schemas at runtime, rendering the appropriate form components and applying validation rules. This approach completely eliminates developer dependency for form creation.

Challenge 4: Complex Multi-Department Workflow

The Problem: Registration approval often involves multiple government departments (press office, security, event management). A simple approve/deny workflow was insufficient for complex verification processes.

The Solution: Implemented a multi-stage workflow supporting registration forwarding between departments. When a registration is forwarded, responsibility transfers while maintaining a complete audit trail of actions, timestamps, and decision-makers. Each department can add notes and verification status before the final approval decision.

Challenge 5: Responsive Data Display with Dynamic Columns

The Problem: The admin dashboard needed to display varying data fields across different events and registration types. A fixed table structure wouldn't accommodate the diverse data returned from APIs, and the interface needed to work across desktop and mobile devices.

The Solution: Built responsive data tables that dynamically render columns based on the API response structure. The table component inspects the data and automatically generates appropriate columns with sorting, filtering, and pagination capabilities. CSS media queries and flexible layouts ensure the interface adapts gracefully to different screen sizes.
