About

Dylan Fernandez de Lara is a generalist software engineer based in New York, NY. I currently work on post-training at Meta and build reinforcement-learning environments for frontier coding agents. That work recently included Muse Spark 1.2 and Muse Code.

Before that I scaled crash infrastructure for Meta Glasses. I studied at Yale. This site is my public notebook: a short profile on the home page, notes when I want to make an idea precise, projects when there is something to inspect, and a record of concerts I played.

I write in public to clarify my own thinking, not to run a product or a developer platform. If you need a professional contact path, a longer biography, or a privacy statement, those pages live on this same domain. The home page remains the profile; About exists so agents and people can find a stable, text-first biography without depending on the card grid.

You can reach me by email or through the profiles listed on Contact. I am the only person who publishes here. Nothing on this site is a Meta documentation portal, and I do not publish private work information.
