React.js development

Build fast, flexible, and scalable web apps with experts

When to choose custom React.js development services

React.js is one of the most popular frontend JavaScript libraries. You’re probably looking for a React.js development company if you’re building some sort of a (usually) single-page application or maybe a progressive web app. And we can help you decide if it’s the right way to go.

(If you know why you’re choosing React.js for your software, go ahead and skip this part. We’re doing this mostly for our SEO person, though also for all the people who really want to know whether React.js is the best option for them. But we can talk to you about it, too, instead of making you read all the extra paragraphs.)

React JS is a frontend library, meaning we’ll use it to build the app elements that users will see and interact with in their browser windows. While you can use it to build larger apps, it’s usually best for building smaller pieces of software like single-page apps or websites and progressive web applications. To create a mobile app, you’ll need to use React Native (for example), which is actually derived from React.js.

It’s often easier to build dynamic web apps using React because it requires less coding than JavaScript and offers more functionality. That’s why it’s so popular with developers and businesses building UIs for software like social media apps, chat apps, ecommerce websites, and more.

Now, to determine whether it is the best choice to build your software in, it’s best if you talk to people who can help you see all the pros and cons and see a larger picture – so not just the functionality but also the future of your app, your user requirements, and the business side of things. 

Which is what we’ll gladly help you with – before we even write a line of code. And if we find a better, more optimal solution, we won’t hesitate to tell you while there’s still time to change things around.

The benefits of custom React.js development

  • SEO-friendly

React.js offers excellent page loading times, which is one of the factors Google’s algorithm really cares about (not to mention something your users will be thankful for.)

  • Reusable

React.js components can be reused, saving time for developers that don’t have to write some features from scratch every time. And this, in turn, can make a massive difference in project timelines and budgets.

  • Easy to build and support

The way React.js was created, it allows developers to create apps fast and then also easily update them. Which means you’re never stuck with something nobody wants to update because it’s just not worth it.

  • Flexible

Due to its modular structure, the code written in React.js is really flexible and easy to maintain. And this usually leads to considerable savings – in both time and money.

  • Community-supported

Like many other open-source languages, React.js has an active community that keeps working to make it more efficient and just an overall better programming language. 

  • Used by many Fortune 500 companies

Thousands of companies worldwide use React.js for their apps. This includes Netflix, PayPal, Lyft, and even NASA. So you’ll be in good company (pun intended.) 

 

If you don’t need the whole package, though, you’ll still get the right experts for your kind of project. They can work alongside your team, or you can just hand over the entire thing to us. We’ll figure that out together first to find what works best for you (and us.)

(If you don’t really need to read the answer to this question, scroll down to learn more about the specific custom web app development services we offer at DeSmart.)

Web app development is – guess what – the development of web applications, backend, frontend, and all. (And yes, we’re doing this for the SEO. Mostly.) Depending on the type of the actual web application, we’re talking about things like

  • The product discovery phase including elements like impact mapping and business canvases. At DeSmart, we’ll use that time to validate your software assumptions and your business model for the software. We’ll also research your target audience, define the features your users want and need, and suggest the best technology to build them in.
  • Backend development for your web app to create the logic and mechanics behind it, making sure it’s stable, scalable, and secure. And that it’s going to last you a long time, even as new tech developments start dominating the market.
  • Frontend development to get you high-performing and good-looking apps your users will love interacting with.
  • Web design and UX/UI services so that they love it so much they won’t want to leave.
  • API integrations with other web apps and software systems, so you can connect it with your internal software or give your users more options by letting them use your app in conjunction with others.
  • Cross-platform app development, so you can get a web app that also looks and works great on mobile devices (and vice versa.)
  • Modernizing legacy web apps to improve their performance, security, and user experience.
  • Growing existing apps with new features, letting you answer your user requests or enter new markets and address new audience segments
  • Quality assurance testing to evaluate the speed, performance, and scalability of your web applications.
  • And more.

What our clients say about our web app development services

We received a great deal of effort for our money, and I’m happy with our collaboration. The quality of work was professional, and their team identified any bugs by themselves most of the time. Based on the ideas we provided, they came back with an improved solution. They also gave us extra product functionalities.
The initial meeting we had with DeSmart before we started the project was really effective. I recommend doing so if you have the opportunity. Also, their communication, speed of development, and expertise were impressive. DeSmart was excellent at providing their own ideas, which benefited the project greatly.
DeSmart is synonymous with service quality. The company works in a truly agile mode, regularly
delivering work increments, which allows to quickly and easily synchronise on requirement details. I was
especially impressed with the dev team’s capability to quickly learn and start using our new APIs.
In terms of deadlines, they performed well. The original timeline was for 15 weeks, and the project was completed in 17 weeks, given that we increased the scope along the way, I would say that's very impressive.
The recommendations contributed to the process by DeSmart, coupled with their questioning of our decisions, have made them stand out. The quality of their work is extremely good.
DeSmart effectively delivered a platform that served as the starting point of our business. My partner and I have been very pleased with the quality of their work!

Will I work with a dedicated contact person on your team?

This really depends on your requirements. We have project managers, testers, and developers on board, and everyone’s equally involved in the project. This means you can talk directly to the developer working on your software and avoid the usual miscommunication that can happen when information travels through the hands and keyboards of multiple people.

Do you use project management software like, e.g. Jira?

Yes, we communicate using Slack and Jira and try not to use email too much. We’re also open to adjusting to the tools your company uses.

Are you a stable company?

Oh, we are. In the past 19 years, we’ve completed over 200 projects and have a full-time in-house team of about 30 people. We’re also the founding members of sodapl.com – the Polish Software Development Association. Go to https://clutch.co/profile/desmart to read what our current and past clients have said about working with us.

Why would I want to work with you?

We’re a boutique software house hiring a maximum of 30 people. Among other things, this means that your project is always a priority for us – we just can’t take on too many projects at a time. We’re also super honest and transparent and will always give you a clear picture of what’s going on.

Our team includes experts with many years of experience, and we’re often asked by other software houses to support them with their projects.

We also have a unique company culture. We’re teal-oriented and value a human approach to software development (which is why “Human-first software development” is our tagline) and work in general. And you can see it both in how we run the company and the way we work with our clients.
