Ori Livneh's new role on site performance - Wikitech-l

8 Oct 2013

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!

Rob
