React.js Development

Overview

LNOKS builds React.js applications for SaaS dashboards, internal tools, and customer-facing web products using TypeScript, modern state management (TanStack Query, Zustand, or Redux Toolkit depending on data shape), and component-driven architecture documented in Storybook. Each project covers accessibility audits against WCAG AA, performance budgets enforced through Lighthouse CI, and test coverage via Vitest or Jest. Founded in 2022, LNOKS has shipped 40+ products with a 5.0 Clutch rating and 96% of clients returning for additional engagements. React engagements deliver a codebase the in-house team can maintain after handoff, with onboarding documentation and code-review patterns documented up front.

What You Get

What you get

  • Web apps

    We build custom web applications such as dashboards, SaaS platforms, and internal business tools. Our focus is on clean architecture, strong performance, and security, so your web app can scale reliably as users, data, and complexity grow.

  • SaaS apps

    We develop end-to-end SaaS products, covering everything from system architecture and UX/UI design to development, billing logic, user roles, and integrations. Our SaaS solutions are built to support growth, recurring revenue, and long-term maintainability.

  • Mobile apps

    We design and develop mobile applications for iOS and Android, either native or cross-platform. Every app is built with real user behavior in mind - smooth performance, intuitive navigation, and stable functionality across devices and operating systems.

  • AI Agents

    We create custom AI agents that automate repetitive tasks, support decision-making, and assist users inside your product or internal systems. These agents are designed to integrate seamlessly with your existing workflows while delivering clear, measurable business value.

Frequently Asked Questions

Frequently asked questions

Yes, we often join existing React projects to extend features, improve stability, or refactor code. We start by reviewing the current architecture, state management, and test coverage, then agree on code-review patterns so our work fits how your team already operates. The goal is a codebase your in-house team can keep maintaining after we hand off, not a parallel system.

We follow modern development patterns, clean architecture, and maintainable coding standards on every React project. Concretely, that means TypeScript throughout, component-driven architecture documented in Storybook, accessibility audits against WCAG AA, performance budgets enforced through Lighthouse CI, and test coverage via Vitest or Jest. Code-review patterns and onboarding documentation are agreed up front so standards survive the handoff.

Yes, React is widely used for complex, high-traffic, and long-term products. We keep large React codebases manageable with TypeScript, component-driven architecture documented in Storybook, and state management chosen for the data shape — TanStack Query, Zustand, or Redux Toolkit. Performance budgets enforced through Lighthouse CI and test coverage via Vitest or Jest keep the application fast and stable as it grows.

React offers flexibility, performance, and a strong ecosystem, making it ideal for scalable applications. It fits SaaS dashboards, internal tools, and customer-facing web products alike, and its component model supports design systems your team can extend for years. We build React projects in TypeScript with documented architecture and onboarding materials, so the codebase remains maintainable by your in-house team after launch.
