Former GNU/Linux System Administrator, now SRE. Debian enthusiast. I like to be always in touch with new technologies and experiment with new stuff. In my spare time, I love to play music and dedicate myself to non-profit causes.

Senior Site Reliability Engineer, Traffic

May 2023 - Present

  • The Traffic team is responsible for WMF’s critical first layer infrastructure, that all user traffic passes through, for all services. This work includes TLS termination (securely encrypting/decrypting web requests), multi-layered caching (both in-memory and on-disk caching to reduce request latency and offload our application servers for a majority of requests), load balancing (distributing requests across multiple servers and ensuring availability of the Foundation’s projects) and GeoDNS (routing user requests to the closest of our caching PoPs to improve request latency). A lot of attack mitigations (e.g. for (D)DoS attacks) are also engineered at this layer.
