      AI Development Review from Julia Antoci

      Leanware built the mobile MVP of our AI fitness assistant for iOS and Android. It started with discovery workshops that sharpened the product vision and shaped an MVP roadmap prioritizing launch features while leaving room for expansions like avatars and real-time feedback. They developed a conversational AI engine with custom prompt and context engineering tailored to fitness conversations, one that keeps continuity across sessions, remembers user progress and preferences, and keeps health guidance within safety standards. On top of that they implemented photo-based food recognition, smart search that understands fitness intent, personalized recommendations, progress tracking with AI-generated insights and coaching suggestions, and gamified response formats that make AI answers easy to read, plus the scalable backend behind it all. Their consultation saved us an estimated 20 to 30 percent in costs by avoiding unnecessary complexity, and we launched a functional MVP across the app stores in under eight weeks, faster than planned. Project management was exceptional: clear timelines, on-schedule delivery, and proactive communication via Slack, with expert recommendations guiding decisions rather than every choice being pushed back to us. Their technical skill and creativity made the whole thing feel less like hiring a vendor and more like building with a co-founder.

      Software Development Review from Anonymous

      Leanware delivered two significant projects for our e-commerce platform along with a steady stream of smaller fixes and enhancements. They built a new employee management page in our back office so our customers can create accounts, set permissions, and link employees to entities on their own, and when our mobile app's chat functionality needed replicating in the back office, they built a custom chat and messaging React library from scratch, integrated seamlessly with our design system and existing bespoke solution. Along the way they worked comfortably across Next.js, React, React Native, Apollo, GraphQL, and Hasura, and adapted to our implicit conventions. We ran week-long SCRUM sprints with check-ins three times a week, and they consistently hit the sprint goals on time; even when we needed hard pivots mid-sprint, they adapted without losing pace. As the engagement progressed they increasingly took the lead, asking well-informed questions and offering suggestions on code, product, and design that genuinely enriched the outcomes. What impressed us most was how swiftly they onboarded: given incomplete product descriptions, they asked the right questions to fill the gaps and picked up our undocumented code patterns without getting stuck on minor details. It felt like one cohesive team working toward shared objectives, free of the friction that usually comes with a third party

      Mobile App Development Review from Anonymous

      Leanware has partnered with us since Q4 2023 on two cloud-based mobile apps for iOS and Android, one built in Flutter and one in React Native, handling development on both and the UI/UX design on one. For one project they staffed a team of five mid-level developers, a senior developer, an architect, and a UX designer available as needed. They also took over an app that was unstable and nowhere near production-ready and turned it into a stable, solid product I'm genuinely proud to show. Their processes leave nothing to chance and the code that comes out of them is excellent; they've been flexible and thorough throughout. They meet deadlines, keep their promises, and are careful about what they commit to. The whole team has been great, and Alvaro, their Technical Product Manager, deserves a special mention for being remarkable. I hired them because they were upfront about what they could and couldn't do, and that honesty, together with the tremendous quality of their work, is what separates them from other providers. Both are getting harder to find these days.

      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

Frequently Asked Questions About React.js Developers

What are the typical React.js development services?

React.js development companies provide end-to-end services that span the entire software development lifecycle, from strategy and design to development and launch. Core services include: 

  • React.js consulting: Guiding businesses on building and optimizing their React applications through component selection, architecture design, and roadmap development. 
  • Custom React.js development: Engineering applications tailored to a business's specific needs, goals, and existing IT infrastructure, and typically include web design and web development.  
  • UI/UX design: Delivering intuitive interfaces, clear user flows, and standardized design systems that align with a brand and its target users. 
  • API integration: Connecting the React frontend to back-end systems, third-party tools, and external data sources to support seamless functionality and user experiences. 
  • Platform migration: Rebuilding or migrating legacy frontends to React to improve maintainability, usability, and performance, often with minimal disruption. 
  • Maintenance and support: Providing post-launch monitoring, debugging, performance optimization, and technical support. 

Many React.js developers also offer specialized expertise, including SaaS products, web application development, customer portals, eCommerce solutions, and minimum viable products (MVPs).  

Some React.js development companies may also offer digital marketing services, such as content marketing, search engine optimization (SEO), and branding. 

What is the difference between React and React Native?

The main difference is that React is used to build web user interfaces, while React Native is for developing mobile applications. Here are more details on their differences: 

 ReactReact Native
Primary platformsWebsites, web applications, and single-page applicationsiOS and Android mobile apps
Tech baseJavaScript/TypeScript with React for web UIJavaScript/TypeScript with React, rendered through native UI components
Best forBusinesses building browser-based products, customer portals, dashboards, eCommerce sites, and SEO-focused web experiencesBusinesses building cross-platform mobile apps for both iOS and Android with shared logic and accelerated development time
ExamplesFacebook, Instagram, Netflix webMicrosoft Teams and Shopify

What are the typical React developer tools?

React.js developers typically choose their stack based on a client's product goals, technical requirements, and existing systems. For example, they may use Formik for complex forms and validation, Storybook for developing and testing components in isolation, and MUI for production-ready UI components and design systems. 

Common React developer tools: 

  • Core front-end: React, JavaScript, TypeScript, HTML, CSS 
  • State and data fetching: Redux, TanStack Query 
  • UI and styling: Tailwind CSS, MUI, Storybook 
  • Testing: Jest, React Testing Library, Cypress 
  • Back-end options: Express, Laravel, Rails, ASP.NET 
  • Databases and infrastructure: PostgreSQL, SQL Server, Redis 

Can React.js developers build AI-powered features into web applications?

Yes. A React.js developer can build AI-powered features into a web application by integrating model APIs, SDKs, and AI workflows into the product experience.   

Depending on your goals, this may include providers such as Google Gemini or Anthropic Claude, along with React developer tools, like Vercel's AI SDK for building chat, search, recommendation, and automation experiences in React-based apps. 

These companies can help you build features such as: 

  • Personalized content and recommendations based on user behavior 
  • Chatbots and virtual assistants for real-time customer support 
  • Smart search with autocomplete, semantic search, and related-result suggestions 
  • AI-assisted dashboards that generate summaries, reports, forecasts, and insights from business data 

When should you hire a React.js development company instead of using an in-house team?

The right choice depends on your project goals, internal capacity, timeline, and need for control. You may want to hire a React.js development company if: 

  • You have a short-term or time-sensitive project, but your internal team is already at capacity. 
  • You do not have the specialized expertise required for the project, such as React architecture, performance optimization, migration, or AI feature integration. 
  • You need to accelerate delivery without hiring and onboarding a full internal team. 
  • You want access to a broader range of skills, such as design, front-end engineering, QA, and post-launch support, through a single external partner. 
  • You need temporary support to fill skill gaps or expand delivery capacity. 

Use an in-house team when: 

  • The application is a core business product that requires long-term ownership and deep institutional knowledge. 
  • The project involves highly sensitive systems, proprietary logic, or strict security and compliance requirements. 
  • You need close day-to-day collaboration, faster internal feedback loops, and direct control over priorities. 
  • The product requires continuous iteration and alignment with multiple internal teams over time.Â
