Silicon Valley-caliber engineering for ambitious products. We build scalable React applications using TypeScript, server-side rendering, and component-driven architecture. From SPAs to complex enterprise dashboards, our React expertise delivers fast, maintainable, and testable applications.
The Bay Area is where much of the SaaS, AI and developer tooling market is built, and buyers here tend to judge vendors on architecture, test coverage and how quickly a team can ship. Investor diligence often reaches the codebase, so clean ownership of code and accounts matters.
Deep integration with Bay Area's SaaS and AI ecosystem. We build products that meet Silicon Valley standards: scalable, investor-ready, and designed for hypergrowth.

Many San Francisco companies already have engineers, and they will read the code you deliver. React work here often means joining an existing repository, respecting its conventions, and leaving behind components and tests that an in house team can extend. For founders without a technical cofounder, it means choosing a stack that the first full time hire will recognise and want to keep.
Framework choice matters more than the library itself. Next.js with server rendering helps marketing pages get indexed, while a client heavy single page app suits dashboards behind a login. State management, data fetching, design tokens and the testing approach should be agreed early because they are expensive to change later. Accessibility should be handled at the component level: focus management in modals, labelled form controls and keyboard support in custom menus, since California courts hear web accessibility claims under both the ADA and the Unruh Act.
Budget follows the number of distinct screens, the complexity of forms and tables, real time features, and how much backend work sits behind the interface. Ask any provider to show a pull request they wrote for someone else's codebase, how they type API responses, what their approach is to bundle size and Core Web Vitals, and whether they write documentation your team can use after the engagement ends.
