Testimonials
What colleagues say
"I had the pleasure of working with Mr. Orbach for about a year. Jacob takes initiative and ownership, consistently identifying problems and solving them without being asked. He is a full-stack developer, comfortable building custom React blocks, integrating backend systems, and handling deployment automation. He reliably takes on complex or unfinished work and delivers results, with a strong focus on building maintainable, reusable systems. He excels at solving problems under pressure, including production issues."
"Jacob joined our company as a junior developer, but was eager to advance and learn new things, and within a year he has successfully completed several significant projects such as our intranet-Salesforce integration using Salesforce API, Microsoft Sharepoint cloud file storage and retrieval using Microsoft Graph and adding e-signature capabilities to our PDF quotes using SignNow API. Our company relies on the systems he built for our day to day business operations. Jacob is a cheerful and hard working individual, fast learner and a pleasure to work with. I would gladly recommend Jacob to any team."
