At LysoformMedical, I developed and maintained backend services and core business functionality for a pharmacy-focused e-commerce platform using C#, .NET, and ASP.NET Core. I introduced RabbitMQ workflows for resilient background processing and optimized PostgreSQL operations, reducing API response times by 20–30% under peak traffic.
I also addressed checkout and bonus transaction race conditions with optimistic concurrency control, and set up centralized logging and monitoring with Serilog, Elasticsearch, and Grafana. I developed and maintained automated tests and React and TypeScript interfaces for the platform and its administrative views.
