Front-End Development Services We Provide

Custom Web Application Development

Imagine a web application that meets all your business needs and work processes. Our specialists will create a progressive custom solution, allowing you to control each development stage. Our frontend web development company will thoroughly study your firm and the market to design and develop the perfect product — on time and within budget. It can be an analytics and reporting tool, e-commerce app, etc.

Progressive Web Apps (PWA)

What do Pinterest, Starbucks, and Spotify solutions have in common? All of them are progressive web applications that provide an app-like experience with offline access, fast downloads, and push notifications. You can create a similar one for your business. Our front end development company will develop an application that will reach the maximum number of users, including those with an unreliable Internet connection or little memory on their devices.

Single-Page App Development (SPA)

One-page programs allow you to load one HTML page and dynamically update its content during interaction. This technology makes Gmail, Netflix, and Airbnb so user-friendly. S-PRO will help you create a similar solution to ensure smooth and prompt user interaction with the program. This is especially important for web applications that require high interactivity. However, such front-end development services require high skill, so we recommend contacting our experienced developers.

Mobile App Development

Thinking about front-end development services for mobile? We’ll help you build any desired platform, whether native (for iOS or Android), cross-platform (for multiple platforms), or hybrid. At the same time, our frontend web development company will analyse the needs of your company, competitors, and target audience to help you find the right solution. In any case, the program will be intuitive, responsive, and with all the necessary functionality.

UI/UX Design

UI/UX design is not only the creation of the general app aesthetics, the choice of colours and typography, and the development of interactive elements. These front-end development services are primarily about researching the consumer and understanding their needs and behaviour. Such an in-depth approach allows you to create convenient navigation and effective user flows. Our front end development company knows how to make a product that looks great and offers a seamless user experience.

Front-End Testing and Quality Assurance

Ensure external software components meet user expectations and offer a positive user experience. Our front end development company will help identify and solve problems. In addition to functional, UI/UX design, compatibility, performance, and accessibility testing, we’ll review code, analyze front-end compliance with project requirements, and implement CI/CD pipelines to automate testing and deployment.
