Common Questions
India has a large pool of experienced React developers with strong English communication, significant time zone overlap with Western markets, and substantially lower rates. Infynno's React developers have shipped enterprise-grade applications including a platform managing 8M+ records for US enterprise clients.
Redux Toolkit for complex global state in large applications (like NoticeNinja). React Query / TanStack Query for server state - caching, sync, background refetching. Zustand for lighter global state. Context API for lightweight, infrequently-updated shared state.
Yes - TypeScript is the default for all React development at Infynno. Typed component props, typed API responses, typed store slices, and typed custom hooks. No `any` shortcuts. This is not optional - it is how our React developers work.
Yes. We use a phased approach - migrating component by component with the existing application remaining functional throughout. Each phase ends with feature parity validation before proceeding.
Your matched React developer works on a real task from your project for one week. You evaluate code quality, TypeScript usage, component architecture, test coverage, communication, and velocity before any long-term commitment.
Yes. We work with agencies on white-label React development - invisible to your clients, operating under your brand, with strict NDA covering client details and deliverables. Your agency's projects, your client relationships, our development.
Three models: full-time dedicated (160 hrs/month), part-time dedicated (80 hrs/month), and hourly (as needed). All include direct developer communication, strict NDA, 1-week trial option, and monthly reporting.
