We've sourced engineers who profile render times and eliminate unnecessary re-renders before code review. They know that working JavaScript and performant JavaScript are different things entirely.
The Philippines has skilled JavaScript developers with excellent English proficiency. Developers stay current with the rapidly evolving JavaScript ecosystem. Cultural alignment ensures smooth collaboration with US teams.
Our JavaScript developers work hours overlapping US time zones by 6+ hours daily. We establish clear communication protocols for real-time collaboration. This ensures responsiveness during critical debugging sessions.
Schedule a call to discuss your JavaScript development needs specifically. We’ll match you with developers experienced in your exact tech stack. Onboarding typically completes within one week.
Our developers specialize in React, Vue.js, Angular, Next.js, and Svelte for frontend. They build Node.js backends with Express, NestJS, and Fastify. They’re proficient in TypeScript, modern build tools, and state management libraries.
Yes, our developers write production TypeScript with proper type safety and generics. They configure tsconfig appropriately and leverage advanced TypeScript features. They understand when types add value versus overhead.
Absolutely, our developers architect with Promises, async/await, and understand event loop mechanics. They handle race conditions, implement proper error handling, and optimize async operations. They debug timing issues that confuse less experienced developers.
Yes, our developers implement code splitting, tree shaking, and lazy loading strategically. They analyze bundle composition, eliminate duplicate dependencies, and optimize for Core Web Vitals. They profile applications and eliminate performance bottlenecks systematically.
Our developers implement Redux, Zustand, Recoil, or Context API based on complexity requirements. They structure state to prevent unnecessary renders and prop drilling. They separate UI state from business logic for testability.
Our developers write unit tests with Jest, integration tests, and end-to-end tests with Cypress or Playwright. They follow test-driven development when appropriate and maintain high code coverage. They structure code for testability from the start.
Yes, our developers implement WebSocket connections, Server-Sent Events, and real-time data synchronization using Socket.io or native APIs. They build collaborative features, live updates, and handle connection state management properly. They optimize for low latency and high concurrency.
Our developers test across modern browsers and implement polyfills when supporting older versions. They use feature detection over browser detection and follow progressive enhancement principles. They leverage transpilation tools to ensure broad compatibility.
Our developers build REST APIs, GraphQL servers, and microservices with Node.js frameworks. They implement authentication, handle file uploads, and manage background jobs with queues. They optimize for concurrency using proper async patterns and worker threads.
