What Would You Pay for This?
Medicover
FitLocker
The application had four major parts:
• Front-end welcome pages on Laravel using classic Blade templates
• Back-end API powered by Laravel
• AngularJS application for trainers
• AngularJS application for other users
From the start, I handled the prototyping and development with only vague customer ideas to guide me. The Laravel website and AngularJS application had custom adaptive styles based on the Bootstrap framework. Grunt was used as the primary building tool.
Interactive Education Catalog and Database
http://bdd-eor.edu.ruTASKS ACCOMPLISHED:
• Unified the authorization between applications using OAuth 2, so materials created within the database could be used within the educational catalog after accounts have been linked. It also allowed the future expansion of the database to other projects.
• Implemented a new functionality for both applications (question types and calendar events).
• Developed a learning system, allowing users to register in the catalog as students and subscribe to courses provided by teachers (originally provided by the database), including a grading system, reviews, and statistics.
• Added new user roles and updated the existing ones so that a user could have different roles within the custom admin panel.
Career4me
http://career4me.ru/TASKS ACCOMPLISHED:
• Created a custom theme for the project.
• Added a lot of new plugins, including integration with an external API and new functionality to create/search resumes and vacancies.

CrossPromo
Kover-vertolet | Online Shop Specializing in Carpets
TASKS ACCOMPLISHED:
• Handled both front-end and back-end development using a provided single-resolution design.
