Web apps & custom development in Seattle, WA.

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

Seattle's economy is led by technology - Amazon is headquartered downtown, Microsoft anchors the eastside in nearby Redmond, and a thick layer of cloud, gaming, and startup companies fills the region - but the city is far broader than software. The Port of Seattle moves cargo and cruise traffic through Elliott Bay, aerospace suppliers feed the regional supply chain, and health systems such as UW Medicine anchor a large medical and research sector. Around those anchors, King County supports tens of thousands of restaurants, contractors, clinics, retailers, and professional firms competing for the same connected customers.

What we deliver for Seattle businesses

Custom functionality

Booking systems, customer portals, dashboards, and calculators built around how your business actually runs, not forced into an off-the-shelf plugin.

Clean, maintainable code

Hand-written, well-structured code that is fast, secure, and straightforward to extend as your needs grow.

Built to scale with you

Architecture that holds up as your traffic and feature list grow, so the app you launch can keep up with the business it serves.

Every web app project covers the build end to end:

→ Discovery to map the workflows, users, and data your app needs to handle
→ A custom interface designed around the tasks your users actually perform
→ Secure, well-structured application code built and tested by hand
→ Integrations with the tools, payments, and services your business relies on
→ Analytics and error monitoring wired in so you can see how it is used

FAQ

Web Apps in Seattle: 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.
