Freelance Drupal Developer

Sean Reiser


Hi, I'm Sean Reiser, a Flushing, Queens based Freelance Drupalist who builds, repairs, maintains and supports Drupal websites.

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!

Drupal Website Support and Maintenance


I maintain websites for small businesses and nonprofits.  

I understand that you don't have the time or expertise to support, manage and maintain your organization's website and you don't have the need to have an in-house developer. I can be your website department. Some of the services I can provide for you include:



I will do a complete audit of your site and document any issues you may have. I will verfy you are up to date, your custom modules and themes follow Drupal's best practices and your site is secure.

Security Updates

I will apply security updates for Drupal Core and Contributed Modules within 24 hours of them being issued by the Drupal community. All updates are tested on a copy of your site before being applied to your live site.

Periodic Updates

I apply other updates for Drupal Core and Contributed Modules on a monthly basis, if possibile at a time when there's less disruption to your users. All updates are tested on a copy of your site before being applied to your live site.


I will ensure you website is up and running, review server logs, ensure backups are working, monitor performance and answer questions about your site. If I am not hosting your site, I will liaise with your host to resovle any issues.


I will repair any bugs on your website. Whether it's an error message, something that's broken or not working or adust thing that don't look quite right.


I will host your site on a platform customized for Drupal. If your site is hosted on a shared host, it can be slower and less stable. Hosting on a platform optimized for Drupal is a quick way to improve your site's performance.

I offer custom subscription plans depending on your organization's needs. I can also offer these services on an a la carte basis.   If you want to ensure that your website is stable and secure please feel free to contact me.
