Loktos Mobile

Project Type

• The project is a Backend Web API application developed with the ASP.NET Core Web API template.
• It provides the service layer required by the Gezdir, Campus Hunt, and Campus Hunt Alumni mobile applications.

Architecture / System Design

• The architecture can be described with two main layers: application and database.
• The application layer represents the backend API consumed by the mobile applications.
• The database layer represents the MySQL database created on AWS RDS.
• The application layer includes multiple internal layers to keep modules as independent and extensible as possible.
• Data access is handled through Entity Framework Core, Dapper, stored procedures, and database views where needed.
• Application security is handled with JWT token based authentication.
• Three-dimensional content is stored on AWS S3 and streamed through the backend.
• The API was deployed on AWS EC2 and traffic distribution was supported with AWS ALB.

Technologies Used

• Backend development: C#, ASP.NET Core Web API 6
• Architecture and data access: Dependency Injection with IoC, Autofac, Generic Repository Pattern, Entity Framework Core 6, Dapper
• Database: MySQL, AWS RDS, stored procedures, views
• Security and documentation: JWT, Postman
• Cloud and deployment: Docker, Docker Compose, AWS SDK, AWS EC2, AWS ACM, AWS ALB, AWS S3
• Version control: Git, GitHub

Key Technical Details and Modules

• Designed the backend according to a layered architecture.
• Managed the database with MySQL Workbench.
• Used stored procedures and views for various database operations.
• Created a Postman Collection document for backend endpoints.
• Designed the database structure required by the backend.
• Deployed the application on an AWS EC2 virtual machine.
• Used JWT tokens for application security.
• Integrated AWS S3 for storing and streaming three-dimensional content.
• Configured AWS ALB to distribute API traffic.
• Added multi-language support at the database layer.
