Hello, I'm Jimmy.
A brief summary of my professional journey so far.
Meta, prev. Facebook · 2019 - 2022
  I started at Facebook in 2019 as a User Interface Engineer. I worked initially on the Workplace product in the Web Core team, where my responsibilities included basically making sure that the web foundations of the product were solid, from the design system to the build system.
I eventually started to own the performance aspect of the product, which was a great opportunity to learn about architecture choices on large scale web applications. Opportunities arose and I got lucky and got to build a performance "squad", a sub-unit of 3-4 people, in order to expand the scope of the performance work.
I got to experience a lot of interesting challenges, from the technical side to the organizational side. There was scope to be had and I was lucky to be there at the right time and at the right place. Experiencing how to build/maintain a team and a product surface was a tough and challenging adventure but I had a lot of fun doing it.
This also led me to cooperate with a lot of different teams, like the Facebook.com Web Infra team and the React team, which was a great opportunity to meet and learn greatly from amazing people.
I then moved to the React Native team, where I worked on performance as well, this time from the perspective of a framework maintainer. It was an interesting episode, where I learned a bit about Android development and how the performance requirements of mobile applications differ from those of web applications.
Vercel · 2022 - current
  I then decided to jump aboard the Vercel skyrocket in 2022 as a Software Engineer. I initially worked on Edge Config product but I decided that I had taken a liking to working on a framework team and I moved to the Next.js team around September.
You probably guessed it, I'm now working on general performance again. I'm also working on a pretty secret thing that I can't talk about yet, but I'm really excited about it.
Don't hesitate to reach out if you want to talk about performance or anything else!
