Based in Freeport, New York, Yellowfin serves small businesses across Long Island in Nassau and Suffolk county and across the United States. Every project is handled directly by the owner. No account managers, no outsourcing, no hand-offs. You get one experienced developer designer who knows your site inside and out, answers when you call, and hands you his direct cell number.
Full service across the entire life of a business website: design and development, WordPress and WooCommerce, SEO, Google Ads, local listings and Google Business Profile, business email setup and migration, hosting, domain management, website repair and rescue, and ongoing support.Â
Veteran-owned (U.S. Marine Corps), Google Ads and Analytics certified, and building websites for nearly three decades. Based in Freeport, serving Nassau County, Suffolk County, all of Long Island, and small businesses nationwide. Nearly thirty years in, and the phone still gets answered!
I founded Yellowfin in 2013 because local businesses deserved a better partner. Most agencies throw technical jargon at you, hand you off to a junior account manager, and disappear when something goes wrong. When you work with us, youre not dealing with a call center or a ticket queue. You have my direct cell phone number. - Stephen Knight, Founder, Yellowfin Development
