Claude and OpenAI developers in USA
Hire Claude and OpenAI developers in USA to build AI agents, chatbots, web apps and mobile apps for your United States business. American start-ups and mid-size companies hire MaddySoft when they want senior engineers without the cost of a full in-house hire. Since 2005 we have built web, mobile and AI software, and today most US enquiries are for Claude and OpenAI features, Shopify and WordPress stores, and dedicated developers who join an existing team.
Free consultation for USA teams
How we work with United States clients
Engagements are billed in US dollars by the hour, month or fixed price, with weekly demos and a shared Slack or Teams channel. You own all code and intellectual property, and we sign an NDA before any discussion of your product.
Time zones
The US East Coast is about 9.5 to 10.5 hours behind India and the West Coast about 12.5 to 13.5 hours behind. Our developers work a split day, so your team gets a live overlap in your morning and finds updates waiting when you start work.
Currency and contracts
Quotes and invoices in US dollars (USD), with a written scope, milestones and NDA before work starts.
Data protection
We build to your privacy and security requirements, including CCPA/CPRA for California users and HIPAA-ready practices for healthcare projects, and we sign NDAs and data-processing terms. We do not claim certifications we do not hold.
Communication
Weekly demos, a shared Slack or Teams channel, and one named project lead.
