About Me#
.NET Developer & System Designer with 3+ years building distributed, event-driven backend systems, including fraud detection and payment infrastructure, with prior experience delivering enterprise CRM integrations on Microsoft Dynamics 365 CE.
Education and Certificates#
- Bachelors in Software Engineering (IAU Tehran South Branch) 2020 - 2025
- MSSQL, Designing Databases and Writing Efficient Queries 2024
My Experience#
Barid Management Solution Development (BMSD)
JAN 2023 - JUNE 2026
.NET Developer & System Designer
- Built an internal productivity tool, generating Mermaid sequence diagrams from a method's call graph, using MSBuildWorkspace and SemanticModel for compile-time code scanning, no reflection. Adopted across teams to speed up documentation and communication around shared modules.
- Designed & implemented a user-behavior analysis engine to detect fraud and abuse (DDoS, brute-force) on gateway traffic with zero added latency to production. Computes behavioral feature vectors from Redis state via NATS-consumed logs, evaluates them against MongoDB-stored rules, and dispatches automated actions (e.g., blocking via Keycloak).
- Delivered enterprise SSO solution as sole technical owner, integrating Keycloak with Active Directory, MS Dynamics 365 CE, and third-party identity providers (OAuth 2.0/OIDC/SAML), deploying Docker infrastructure.
- Improved performance of a data-intensive SMS handling system integrated with the CRM, used in one of the key products, by 10x, reducing processing time from 10 minutes to 1 minute by optimizing database queries and fixing concurrency implementation issues.
- Led Developer Education Program: designed curriculum and delivered technical training on Unit/Integration Testing and Identity Management, establishing quality standards and modern development practices for engineers.

Projects#
Cross-Platform Download Manager#
Desktop download manager built with Avalonia UI, targeting Windows and Linux. Implements chunked downloading over HttpClient splitting files into byte-range segments for parallel transfer, with resume support that persists downloaded byte ranges to a temp file, allowing interrupted downloads to continue without re-fetching completed chunks.
SMS Middleware Modernization#
Redesigning and rebuilding a legacy .NET Framework SMS middleware from the ground up on .NET 8+. The system bridges Dynamics 365 CE with multiple SMS provider APIs. It handles routing, bulk campaigns with interrupt recovery, and delivery state tracking. Replacing WCF with minimal APIs, hand-rolled concurrency with WolverineFX over RabbitMQ, deprecated CRM SDK with Dataverse.Client, and adding structured observability via Serilog.
FastCrud#
Contributor; built the xUnit/FluentAssertions test suite, uncovering and fixing bugs.
