Working on a cloud-based apartment booking system as a full-stack developer, building and maintaining a scalable solution using React on the frontend and ASP.NET Core on the backend.

Responsibilities:

• Designing and developing RESTful APIs for user, booking, and apartment management.
• Performing database operations using Entity Framework Core and Dapper, including support for complex statistical queries.
• Writing robust unit tests using xUnit, Moq, and FluentAssertions to validate business logic and integration points.
• Assisting in CI/CD pipeline configuration using GitHub Actions to support smooth automated builds and test runs.

Achievements:

• Optimized database queries and caching logic, reducing latency (API response time by 40%).
• Migrated nearly 10,000 records from large JSON datasets into PostgreSQL with an atomic, failure-resistant process.
• Implemented secure and scalable user authentication and role management, improving overall data security and access control.
• Increased test coverage from 30% to 70% in the application layer, strengthening reliability of business logic.
• Diagnosed and fixed a CI issue where test results were not collected, enabling full test report generation and visibility in PRs.
