Connection multiplexer for GoLang: serve different services on the same port!
Role in this project:
Back-end Developer
Back-end DeveloperContributions:6 releases, 81 commits, 51 PRs in 2 years 6 months
Contributions summary:Soheil primarily contributed to the development of connection multiplexing features for the GoLang project, `cmux`. Their work involved implementing HTTP/1 and HTTP/2 field matching, including header parsing and handling. They also added examples for serving HTTP and HTTPS on the same port and for recursive muxing, demonstrating the core functionality of cmux. Additionally, they added WebSocket support and optimized the code by eliminating unnecessary copies and reducing allocations.

The C based gRPC (C++, Python, Ruby, Objective-C, PHP, C#)
Role in this project:Back-end Developer
Back-end DeveloperContributions:92 reviews, 225 commits, 194 PRs in 2 years 11 months
Contributions summary:Soheil primarily focused on optimizing the gRPC codebase. Their contributions include improving error handling and optimizing performance through the implementation of cycle counters. They also improved the performance of the library by implementing a fast path for the resource quotas, and avoiding allocations where not needed. Moreover, the user made various code-style related changes, and addressed build and test failures.
