About Me

My name is Rafael Baptista. I lead teams who build iconic digital products used by millions of people every day.

I'm currently working on an online travel agency called SkyMonde.

I was previously Head of Product at KAYAK. I built a very successful multi-brand SEO program for them that also included brands like OpenTable, Momondo, CheapFlights, Swoodoo, Checkfelix, and HotelsCombined.

I occasionally advise startups on SEO, the most successful of which is Insurify.

Previously I was CTO of Mimoco and worked on SEO at TripAdvisor focused on flights and vacation rentals.

For many years I was a game developer, helping make games for Harmonix, Apple, THQ, LucasArts, Nickelodeon, Ubisoft and many others. My biggest selling game was the Rockband Series.

I've worked on speech recognizers at Kurzweil, and genome mapping at the MIT/WIBR Human Genome Center.

I wrote the web server that this site runs on.
