At Narin Afzar Sahand, I develop and maintain SafarVIP backend APIs and services using ASP.NET Core, Dapper, and T-SQL. I optimized stored procedures and high-throughput queries across SQL Server databases containing millions of transaction records.
I integrated Sepas (RMTO third-party services), syncing 10,000+ daily transit records at 99.9% accuracy. I apply Clean Architecture and SOLID principles to improve maintainability and quality.
At Beman Agency, I developed backend services for 20+ enterprise applications. I optimized database operations to reduce query execution time for workloads supporting 300,000+ active users, and refactored legacy projects to improve maintainability, readability, and performance.
At Safar724, I developed platform features and backend services, maintained REST APIs, and improved production observability using OpenTelemetry, Elasticsearch, and Kibana. I also have hands-on experience with microservices, distributed systems, and production monitoring.
