Web-platform with 4,120,000 locations on the map

Описание

There was an outdated version of the system. It was di"cult to !nd developers for the obsolete technology (ASP.NET). At the same time, it was important to start adding new functionality in the shortest possible time and bring them to the market. An additional problem was slow operation of the system (loading of the pages took more than 10 seconds), users #ooded support service with messages. Also, the data in the system was incomplete, it was necessary to integrate with the new data providers. This, in turn, have led to point increase on the map by 2 times. The time was limited Goals - We transferred the system to modern technology within 4 days - The number of users increased, and the number of calls to the support service fell to 2 per day after 3 weeks - We added 4 million objects to the map - We optimized the speed of loading pages from 10 seconds to 1 second without changing the hardware - We updated the map to the latest version - We implemented new functionality in a quiet mode during 7 months - We added support for mobile devices Role - Full stack developer Team Size -4 Developers, 1 QA and 1 Project Manager

Learning Management System (LMS)

Описание

It was necessary to develop a learning management system. The system have to include webinar rooms, an assessment center, system to upload/modify courses, monitoring the progress of students. It was necessary to develop the product iteratively, releasing a new stable version every 4 weeks. Solution As a development methodology, SCRUM was selected with an iteration of 2 weeks. At the end of each iteration, demonstration was carried out to customers and users. The team was to consist of 7 developers, 1 designer, project manager and 2 testers. As a technology platform, platform from Microsoft (.NET) was taken. It was decided to maintain the widely used SCORM standard in the system. This would allow new customers to easily transfer their courses from their old platform to our new one. Goals -Potential clients were invited on development demonstrations (showcases), this allowed to increase sales of the platform even at the time of development - Every 4 weeks there was a new stable version of the product - Users and customers were involved in the process and provided timely feedback - The system supported the SCORM standard, this allowed new customers to quickly move their courses to a new platform Role - Full stack developer Team Size - 7 Developers, 2 QA, 1 Web-Designer and 1 Project Manager.
