Web apps & custom development in San Diego, CA.

Need a custom web app for your San Diego, California business? GEO Marketing Group designs and builds booking systems, customer portals, dashboards, and calculators for San Diego companies, working remotely from our Providence, RI studio. We build the custom functionality a template cannot handle, with clean code you own outright.

San Diego's economy runs deeper than its reputation as a coastal destination. The region hosts the largest concentration of military installations in the United States - Naval Base San Diego, MCAS Miramar, and Camp Pendleton among them - anchoring a massive defense and contracting sector. The Torrey Pines and La Jolla corridors are home to a dense cluster of biotech and life sciences companies, and UC San Diego drives research and talent that feeds both sectors. Healthcare systems including Sharp HealthCare and Scripps Health are major employers, the Port of San Diego serves cruise, cargo, and naval activity while cross-border trade with Tijuana and Mexico flows largely through the Otay Mesa land port of entry, and tens of thousands of restaurants, contractors, retailers, and professional firms serve a sprawling, affluent metro. For all of them, customers start with a search on their phone.

FAQ

Web Apps in San Diego: common questions.

What kind of web apps do you build?

Booking and scheduling systems, customer portals, internal dashboards, calculators, and other custom tools that go beyond a brochure website. If your business runs on a workflow a template cannot handle, that is exactly what we build.

Do you work remotely with businesses outside Rhode Island?

Yes. We are based in Providence, RI and build for clients across the US and Canada, working remotely by phone, video, and email. Web app projects run smoothly from anywhere.

Do I own the application and its code?

Yes. The code, the hosting accounts, and every integration are set up in your name and handed over at the end. You own the app outright and are free to host, extend, or move it however you like.
