Frontend Development

Build usable, high-performing apps for all screens and devices

Why go for outsourced frontend web development services?

Your app’s frontend is like your storefront. It’s what your customers engage with when they use your service or buy something in your store. And it’s often the deciding factor in how successful your software product is. Whether it attracts users and makes them stay. Or makes them drop out and never come back.

That’s why your frontend development company or in-house team should not be just people who code. It should be people who get your business and understand your users and how they’ll interact with your product. They need to be fluent not just in the latest frontend development technologies and frameworks but also in user experience design. And they need to have a strategic approach to software development.

At DeSmart, we’re just that kind of people. With a people-first approach, we do much more than just produce frontend code. We’ll help you go from a product idea to functional software that’s ready to be launched on the market and start making the profit you’ve intended it to make.

Whether you need extra frontend developers to support your team or want to hire a frontend development company to take care of your app end-to-end, we’re your people. 

What does frontend web development include?

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

Frontend development includes a bunch of different areas with one thing in common –  they’re all on the “front” of your web app where your users can see them. This involves things like:

  • How the user interface works and performs, including navigation, menus, buttons, animations, user interactions, and more
  • Implementing the design to create the look and feel of the website or app
  • Responsive web design, making sure the look and feel and performance are equally great on all devices and screen sizes
  • Your website or app’s accessibility
  • And more.


Tech stack-wise, frontend development services are usually based on HTML, CSS, and JavaScript plus native application environments like Flutter or React Native. The two latter allow for creating cross-platform applications independent of any one platform, helping you build web apps more efficiently. And it so happens that DeSmart frontend developers specialize in these, so read on for more of what you can do with us.

Our Front End Development Tech Stack

Our frontend development projects

We've completed dozens of successful frontend development projects in the 20 years we’ve been creating software at DeSmart. And we’ve worked with our clients across the entire project development spectrum – from validating ideas and selecting the tech stack until market launch and then maintenance.

What our clients say about our frontend web development services

DeSmart Software Development has succeeded where several other companies have not. I started this project with a certain vision of what I wanted, but no other companies have been able to provide me with what I wanted. With DeSmart Software Development, I have gotten what I wanted and more.
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.
I’d highlight that their ability to adapt is exceptional. We didn’t go with a fixed scope and ended up with a different product than we’d had in mind. They were accommodating of changes and adjustments. That made them very easy to work with. They were also very transparent about pricing, which we appreciated.
I was impressed with their developers' efficiency, speed, and flexibility . Cooperation was smooth and uninterrupted. Monitoring of resource consumption to be improved. Great culture fit. Good value for cost. Company values aligned.


We realize you might not be familiar with all the aspects of the software development process. So here are a few pointers and explanations you might find helpful. And if you have more questions, send us a message, and we’ll get back with the answers.

What are the first steps when we start working together?

1.We always start with consulting your project with our product and business teams to see if we’re indeed a good fit.

2.We’ll then create a cost estimate and a proposed timeline.
Then we’ll organize workshops to help us define the business and product requirements so that we can build the best software solution for your needs. The people who took part in the workshops will make up the foundation of your project team.

3.We sign the contract and set up a kickoff meeting to nail down all the project details.

What are the benefits and drawbacks of the technologies you use?

Our development team will talk you through all the benefits and drawbacks of a specific technology for your specific project so that you know all you need to know to make your decision before you actually make it.
One of DeSmart’s core values is transparency, and we always inform our clients about any risks involved.

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 – the Polish Software Development Association. Go to 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.

What are frontend and backend services?

The frontend of your app is essentially the user interface – what your users see and interact with. The backend is all that’s quite literally in the back – the server infrastructure, the app architecture, the database, all working behind the scenes so that your users can actually get a functional app that does its job and performs as expected.

At DeSmart, we offer both backend and frontend web development services – alone or in combination, depending on the needs of your project. And we can help you define those needs and turn them into specific requirements during our initial workshops.

What are frontend operations?

Frontend ops, as the industry likes to call them, are essentially ways to optimize software code on the client-side to boost its performance. They involve continuously monitoring the UI to fix bugs, optimize assets, oversee new version migrations, and generally make sure that the app looks and works at its peak performance for your users at all times.

We can offer frontend operations services for your app at DeSmart – give us a shout if this is something you’re looking for.

Are web services frontend?

The “web” in “web services” can be confusing, because when we talk about web services, we usually mean client-server applications communicating over a network. So they in fact allow for easy communication between the frontend and backend.

Not to be mistaken with web applications – apps accessed via a web browser on a user’s device. (If you need either, though, let’s talk – we can help.)
