👤
Senior🎓
Top SchoolRanjeeth Dasineni is an engineering director based in Los Altos with 12 years of experience building high-performance networked systems, currently leading SDN work at Backbone Networks within Facebook. He combines deep systems engineering roots—shipping HTTP/QUIC, load balancers and CDN features—with management experience across Palo Alto, London and Menlo Park. A hands-on coder at heart, Ranjeeth has contributed notable C++ work to high-profile open-source projects like facebook/proxygen and folly, adding HTTP/2 protocol improvements and an LRU EvictingCacheMap implementation. His background spans ML, AI and computer vision from graduate study at IIITH, giving him a rare cross-discipline view that informs pragmatic systems design. Known for fixing tricky cross-platform build issues and protocol-level ergonomics, he excels at turning low-level protocol details into scalable production features. Colleagues rely on him to bridge research-quality ideas and production-grade networking infrastructure.

facebook/folly
Jul 2014 - Oct 2015
An open-source C++ library developed and used at Facebook.
Role in this project:Back-end Developer
Back-end DeveloperContributions:8 commits in 1 year 2 months
Contributions summary:Ranjeeth primarily contributed to the `folly` library, focusing on improving and extending its functionality. Their work included implementing an LRU cache (`EvictingCacheMap`) with constant-time operations and customizable eviction, as well as refactoring and correcting code related to string manipulation and conversion functions within the library. Furthermore, the user addressed compiler warnings and corrected conditions to resolve potential build issues across different platforms. They also added a client-side protocol filter for SSL sockets, providing enhanced flexibility for network protocol selection.
