Worked on the igrowker/i004-reffindr-back-dotnet and nodejs repositories to deliver core backend features for user authentication, property management, and data integrity. Built secure onboarding with JWT-based authentication, implemented property listing APIs, and enhanced user image handling using Azure cloud storage. Improved database migrations and cloud connectivity, introduced metrics tracking with Prometheus, and refactored form data handling for reliability. Applied C#, TypeScript, and SQL to design robust APIs, manage data models, and ensure scalable deployments. Focused on maintainability through service layer patterns, DTOs, and dependency injection, while strengthening observability and supporting environment-specific configurations for smoother production workflows.
