What I'm looking for

I’m looking for remote-friendly roles where I can modernize .NET backend systems, own architecture decisions, and build secure, high-performance APIs with strong CI/CD practices—especially in enterprise SaaS or payment-driven products.

I’m a Senior Software Engineer (.NET) with 9+ years of experience building scalable backend systems, enterprise applications, and distributed services using .NET technologies. I focus on backend architecture, enterprise modernization, payment integrations, CI/CD pipelines, cloud-hosted applications, and high-performance API development across financial systems, SaaS platforms, and ERP solutions.

Most recently, I redesigned payment workflows by migrating from Avangate to Paddle, improving operational efficiency by 30%, and I built a secure .NET-based Paddle integration service to strengthen maintainability and deployment management. At the Central Securities Depository of Iran, I modernized a legacy brokerage platform for 130+ brokers and supported authentication workloads up to 1000 RPS, improving reliability and maintainability using Clean Architecture and DDD while helping drive complex legacy database migration and synchronization. Earlier, I transitioned from mobile to backend framework engineering, created reusable infrastructure components (including an exception handling middleware that improved development efficiency by ~20%), and built Android ERP systems with offline-first architecture, local SQLite synchronization, and internal tooling to boost productivity.
