From simple business websites to full-stack web applications — built clean, built fast, and optimized to rank for Nassau and Suffolk County searches. Based in Oyster Bay, NY since 2006.
The Problem with Generic Web Agencies
Most Long Island businesses either have an outdated site that doesn't reflect what they actually do, or a template-built site that looks like everyone else's and ranks for nothing. A website that can't be found, or doesn't convert visitors into calls, isn't an asset — it's a missed opportunity.
Gold Coast Tech builds custom websites and web applications from scratch — no page builders, no cookie-cutter templates. Every site is written in clean code, designed with your customers in mind, and optimized from day one to rank in local Long Island searches.
What We Build
Whether you need a professional business site or a complex web application, we have the experience to build it right.
Purpose-built websites designed around your brand, your customers, and your goals — not a template with your logo dropped in.
Database-driven platforms, client portals, booking systems, membership sites, and custom web apps built in PHP, JavaScript, and MySQL.
Online stores built to sell — product management, secure checkout, inventory control, and a shopping experience your customers will trust.
On-page SEO, meta optimization, structured data markup, Google Search Console submission, and content targeting Nassau and Suffolk County search terms — built into every project.
Custom WordPress themes, plugin configuration, performance tuning, and security hardening — for businesses that want an easy-to-manage site on a proven platform.
Fast, reliable hosting with ongoing maintenance, security updates, backups, and support — so your site stays up, stays secure, and stays current.
Who We Work With
We work with businesses across Nassau and Suffolk County that need a web presence that actually performs — from a first-time website to a complete platform rebuild.
"What impressed us most was their ability to execute a two-year project with minimal disruption to our active care operations. Their team was professional, communicative, and truly cared about getting it right."
