      Python Django Review from Andrew Stetsenko

      We partnered with Flyaps to build the GlossaryTech Chrome Extension from scratch, including the backend for tech terminology analysis. The goal was to help recruiters, sales professionals, and other non-technical specialists in IT quickly understand the technical terms they encounter every day.The first release shipped back in 2017, long before today's AI tools were available off the shelf. Flyaps built a custom tokenization layer on top of NLTK library to resolve the ambiguity problem - distinguishing "Go" the language from "go to the shop," or "Swift" the framework from the adjective, while also correctly recognizing multi-token terms like "Ruby on Rails" or "Amazon Web Services". It was a pragmatic, precise solution that made the extension genuinely usable from day one.The outcomes have validated that early bet. GlossaryTech now holds "Featured" status in the Chrome Web Store, has passed 25,000 downloads, and consistently serves 10,000+ weekly active users and 2,000+ daily active users. For a niche professional tool, that level of organic, sustained engagement is rare - and it traces directly back to the technical foundation Flyaps put in place.Beyond the engineering, what stood out was how Flyaps engaged with the product itself. They contributed to architecture decisions, flagged edge cases early, and treated scope conversations with honesty rather than upsell. Communication was straightforward throughout, deadlines were met, and the codebase has held up well as we've extended the product over time.I'd recommend Flyaps to anyone looking for a partner who combines solid engineering with genuine product thinking. They've been central to GlossaryTech's success and continue to be a team we trust.

      Software Development Review from Dariia Ryzhova

      Our collaboration with Flyaps has lasted for several major projects, of which I personally worked with them on two. I am very satisfied with the level of expertise (both technical and domain), the involvement and responsibility of the teams, and the quality of delivery. We successfully brought 2 major products to life together. Flyaps teams have diverse specializations, so I had the opportunity to attract consultants from different fields: software developers, including high-level architects, DevOps, QA, and business analysts.The teams have a modern technology stack and are experienced in Agile development. This allowed for smooth integration with internal teams and processes. It is also important to note that Flyaps provides technical consulting on demand, and this was very valuable service as well. Overall, I can recommend working with Flyaps as a reliable and high-quality partner.

      ТОВ ХОТНАЙТС's Review Sourced from Google

      Flyaps delivered outstanding results for our e-commerce store! They built a visually stunning and high-performing website that perfectly captures our brand. Since launching, our site speed has improved by over 60%, and we've seen a noticeable increase in our conversion rate. Their team's technical expertise is top-notch, and the new admin panel they created has made managing our operations so much easier. I am happy to recommend this team of professionals.

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.
