About bit15

Welcome to my website!

bit15 is a one-person operation. My name is David Acosta-Juan. I've been working the web since the early years, covering a range of projects going from web design and development to database applications taylored for specific needs. In two decades, I went through a wide range of technologies, and witnessed the birth, thriving, and sometimes fall, of coding languages, operating systems, and information-process paradigms; and in that journey I learned how to choose, from a toolbox full of resources, the ones that do the work best, while also having the longest lifespan spectations.

I started working with databases in 1996; and have used a wide range of server-side engines since then, from ColdFusion to PHP and JSP.

Some of my work in these 20 years included the creation of the first online video rental store in Mexico, for Columbia Tristar Homevideos (now a division of Sony Entertainment); the online music community Click 2 Music, for Bertelsmann Mexico (BMG); the website of the Mexico Cart Grand Prix 2004, for OCESA; and countless sites for small businesses, art galleries, photographers, private schools, musicians...

I've been a resident in the United States since 2013. In the last years I've been working for several projects in the U.S., while still mantainining some of my work in Mexico.

You can count on all my work to be:

Fully Responsive
