Tallinna Linnatransport – Renewal of the Intranet and Public Website

August 19, 2025

Challenge
Tallinna Linnatransport (TLT) needed a complete overhaul of both its intranet and public website. The new solution had to be user-friendly, secure, accessible, and meet the needs of diverse target groups – from citizens to employees and business partners.

Solution
Krabu Grupp carried out a comprehensive renewal project which included:
• creating a new design framework in line with TLT’s brand guidelines;
• developing a user-centered Mega Menu and personalized homepage views for different user groups;
• adding modern features such as ID-card, Mobile-ID and Smart-ID login, dark mode, and dynamic submenus;
• ensuring mobile-friendly responsive design and multilingual support (Estonian, English, Russian);
• implementing accessibility improvements in line with international standards;
• optimizing site performance (lazy loading, CSS/JS minification, caching, server-side rendering) and strengthening security with a multi-layered protection system.

Result
The renewed website provides TLT with:
• significantly improved user experience across all devices,
• smooth and fast navigation through the Mega Menu and personalized views,
• secure and reliable access to internal information,
• better visibility in search engines thanks to technical optimization.

With the new solution, TLT can offer employees, customers, and partners a clear, trustworthy, and convenient digital channel that supports daily operations and strategic goals.

Moodle Platform Customization

Moodle Platform Customization

April 29, 2025

Challenge
A rapidly-growing private-sector company needed a simple, auditable way to prove that every employee had read and acknowledged mandatory internal documents.

Solution
Krabu Grupp extended the customer’s Moodle learning environment with a custom Document Sign-Off plugin. Once an employee finishes reading, they set the status to Done; the system instantly stores the user, timestamp and document version and feeds the data into a real-time compliance report.

What is Moodle?
Moodle is an open-source Learning Management System (LMS) used in more than 200 countries to build e-learning courses, manage content and track learner progress.

Impact
• 100 % visibility of employee acknowledgements
• Sign-off cycle shortened from days to minutes
• Automatic audit trail exports for HR and compliance teams
