TAIS

Developer

TAIS is a Departure Control System designed to streamline operations for airports and ground-handling companies. It's part of the comprehensive TAIS Airline Solution or DCS, automating every step of airline passenger service from check-in to departure. Denis played a key role in enhancing this system by developing a registration form for Expedite Baggage, facilitating efficient baggage check-ins and enabling the display of baggage receipts. Moreover, he introduced features to print receipts and automatically complete the registration form by scanning the baggage tag, significantly improving the system's efficiency and user experience.

Leroy Merlin

Developer

For the Leroy Merlin company, an upgrade was made to their "Calculation Sheet," a tool aimed at automating the display of wage and bonus data. Denis was instrumental in this enhancement, creating a solution that featured two main sections: wages and progress awards. This tool was designed to dynamically present data, capable of adjusting based on a sophisticated filtering system. Additionally, Denis incorporated a functionality for uploading PDF documents, further streamlining the data management process. This updated tool was designed as a microservice, seamlessly integrated into the existing system while ensuring a fully responsive design to accommodate various device screens.

Scoperty

Developer

In the development of Scoperty, an application aimed at simplifying the process of renting, selling, and buying real estate in Germany, Denis contributed as a client-side developer using Angular 7 for the MVP phase. Following the application's launch and during its subsequent growth, Denis enhanced its functionality by customizing and integrating a Google Maps feature directly into the platform. He engineered a sophisticated function that would automatically update the map's data representation at various zoom levels. For more granular detail, he replaced standard clusters with polygons to accurately delineate the perimeters of actual property plots. This advanced mapping feature was also designed to be fully responsive to the application's filtering system, ensuring that the map's visual elements dynamically adjusted to user-defined search criteria, thereby improving the user experience in navigating real estate options.
