Re: [Wikitech-l] Ori Livneh's new role on site performance

Hi everyone, I'm excited to announce that Ori Livneh will be moving into Platform Engineering as Senior Performance Engineer. This work is riffing off of the work that he's done with the Growth (nee E3) team, where a big part of his job was instrumenting new features to measure their impact on editor retention. In his new role, Ori will be responsible for many aspects of site performance. There are a couple of different things one can optimize for when optimizing site performance: hardware cost or end-user experience. The best optimizations do both, but for some optimizations you need to choose which is more important (e.g. buying new hardware in order to increase responsiveness). Ori will mainly be focusing on the end user experience, and will be doing so in an end-to-end fashion (even looking at rendering performance on end-user machines). Ori's day-to-day tasks will involve instrumenting the site such that developers can see the impact of their work on site responsiveness. He'll also work closely with our TechOps team, making recommendations on site configuration that can have a big impact. He's also going to spearhead the investigation and likely implementation of performance-related technology on our cluster. There will also be a lot of smaller changes that it'll make sense for Ori just to tackle rather than waiting for someone else to do them, so he'll likely spend a chunk of his time doing that as well. Ori has done tremendous work in the year and a half he's been here in bootstrapping the Growth team, and we're really excited to see what he will achieve in this new role. Welcome, Ori!
