Web application development in California

Start with a web app when people will mainly use your product at a desk or share it through a link. A mobile app first is a stronger fit when the product centres on the camera, location or daily notifications. That choice changes which screens and interactions need attention first, so describe the task your users need to complete before choosing a format.

Hosting is another decision. Managed platforms such as Vercel, Supabase and Firebase reduce setup and server upkeep. Running directly on AWS or Google Cloud gives you more control and can cost less at scale, though it also brings more operations work. The choice affects what your team will need to maintain after the product is running.

For a product serving several customers, a shared database is simpler to operate. Separate databases suit enterprise customers with strict isolation or data-location requirements, with more infrastructure to manage. We help you decide what belongs in the first version and plan what comes next.

For a business open to the public, US guidance says the ADA covers goods and services offered on the web and points to WCAG as helpful guidance. We include checks against that guidance when designing and testing public-facing screens, so accessibility is considered in the build.

If your product charges subscriptions, US businesses can sign up to accept payments with Stripe. We set up Stripe Billing when a proven billing service fits your pricing model; unusual pricing or strict data rules can call for a custom approach.

Bring what you have and tell us where you need help defining the product.

• Your users, the job they need done and how they do it today.
• The competing tools they use and what is missing from each.
• Any designs, prototypes, repositories, domain and hosting accounts, with admin access.
• The personal or sensitive data you expect to hold and any customer security reviews.
• Your first-version prioritieswhich features users need before the product is useful.

• !

  Building every account and billing component from scratch can consume budget on work users never notice. Consider proven services before commissioning custom components.

• !

  Adding customer data separation late can force a risky rewrite. Design it into a multi-customer product from the first version.

• !

  Payment events can arrive more than once or out of order. Build handlers that skip processed events and do not depend on their order.

• !

  Releasing without staging or tested backups leaves mistakes to become live incidents. Keep a test environment and check that backups work.
