About CustomBytes

CustomBytes is an Alpharetta, GA-based custom software development firm founded in 1996 by Andy Feibus, a 40-year software industry veteran. The firm builds web-based, desktop, and mobile applications across e-commerce, reporting, manufacturing, and process monitoring. Their technology stack spans .NET (C#, VB), C/C++, Java, PHP, MySQL, Oracle, and SQL Server. Known for their money-back guarantee on the first $15,000 of a project, CustomBytes serves small and mid-market businesses with a personalized, consultant-led engagement model.
