United States
Custom software and websites for U.S. businesses—built remotely.
Proton Technologies Limited is a Hong Kong company. We work with U.S. businesses remotely on custom business software and professional websites.
We do not operate a United States office. Collaboration happens by email, video, and shared project tools, aligned to the client’s working hours as far as practical.
What we build for U.S. companies
Custom business software is software designed around a specific company’s workflows, users, rules, and operational requirements rather than a standardized product sold to many unrelated businesses.
Website design and development covers custom design, responsive implementation, technical SEO foundations, performance, and functionality the business actually needs—including additional pages, integrations, or ecommerce/portals when those are scoped separately.
How remote collaboration works
Projects typically start with a written description of the workflow or website need, followed by discovery calls. Time-zone overlap with U.S. East and West Coast hours is used for working sessions; asynchronous updates cover the rest.
After launch, support continues through the same remote channels. Pricing for websites starts from $200 for a clearly scoped site; custom systems are scoped after the workflow is understood.
