Freelance Drupal Developer

Sean Reiser Self Portrait



Hi, I'm Sean, a New York City based Web Developer who builds, repairs, maintains and supports Drupal websites.

Over the past 12 years I've had a role in building over 150 Drupal Websites for Non-Profits, Small Companies, Digital Agencies, Media Companies and Startups.

About Me

Professional Biography

For lack of a better description, I'm a bit mason. I come from a family of brick masons who used trowels to shape bricks and mortar into buildings; to continue the family tradition, I sit at my shiny computer and use Drupal, PHP, HTML, Javascript and CSS to shape bits into dynamic websites.

Often I build sites on my own but, depending on your needs, I can hire outside contractors to get thing done faster.  If you have a team in place and need another resource, I can work at your location with your team.

Please feel free to look through the rest of this site and evaluate my experience. Contact me if you decide I can be of service to you.

Good luck with your project!
