Design Thinking We Adopt

Design thinking is an approach to developing product’s UI/UX. As a full-stack front-end development company that pays extra attention to aesthetics and user satisfaction, Devox adopts a design thinking approach, emphasizing empathy, user-centeredness, creativity, and collaboration. This is how we tackle complex problems and harness innovation for your next app, regardless of its purpose and complexity – all to make a truly user-friendly product that brings value to your clients.



We get acquainted with your project requirements and needs, seeking to understand your audience and shape design goals accordingly. At this stage, we put an emphasis on empathy, striving to understand the field and set tasks for further research.



This is when we paint a portrait of your potential user, answering all the related questions about them. We construct user persona, define the role objectives, calculate challenges and spot the pains. You will get a competitive analysis and a customer journey map.



It’s time for ideas generation: you can join us in this process or fully delegate it to us. We’re working out a structure and layout, delivering wireframes, user flow, information architecture, business model canvas and value proposition canvas.



This stage is where the creativity takes physical shape. We deliver mockups and storyboards, developing a custom style with style-picked color palettes and typography. Eventually, you will get a clickable prototype that your users may check and give feedback on even before the application is developed, UI style guide, motion and design system.



Finally, we monitor user behavior to understand what works in terms of design and what doesn’t. We form focus groups and use different tracking tools, conducting different types of testing (A/B testing, usertesting, screen-tracking) and thoroughly gathering feedback.

Patterns We Choose for Front-End Development

MVC (Model-View-Controller)

A design pattern mostly used in web applications that separates the app into 3 interconnected components: Model (data and business logic), View (user interface), and Controller (mediator between Model and View, handling user input).

Modular Architecture

An approach that organizes a software system into separate, self-contained modules. Each module focuses on a specific functionality or a feature, making the system easier to develop, maintain, and scale.

Micro Frontends

An architectural pattern that extends the microservices concept to the front-end. It involves breaking down the user interface into smaller, independent modules or applications that can be developed, deployed, and scaled separately. Each micro frontend typically has its own technology stack.

Component Architecture

A design approach that structures software systems as a collection of reusable, self-contained components. Each component represents a piece of functionality and can be combined to build more complex applications. This concept is commonly used in front-end development with frameworks like React and Angular.

Dumb-Smart Components

In component-based frameworks, "Dumb" and "Smart" components describe two types of components. Dumb components (also known as "Presentational" or "UI" components) are primarily responsible for rendering user interface elements. Smart components (also known as "Container" components) handle business logic, data fetching, and state management.

State Management

The process of managing and maintaining the data and application state in a software system. It involves storing and updating information, such as user input, application settings, or data retrieved from external sources. Effective state management is crucial for maintaining a consistent and responsive user experience.

What You’ll Get with Optimized Front-End

Leverage Responsive Design

Devox team constructs the layout in diligent accordance with Gang-of-4 principles: we leverage responsive design techniques, ensuring that your content provides a consistent experience across all devices and offers an understandable user path. You will get intuitive and visually appealing user interfaces, making it easier for users to navigate and interact with your website or app. Simplify the user journey, reduce friction, and encourage users to take desired actions, increasing conversion rates at once.

Achieve Cross-Device Compatibility

Well-done front-end development services ensure that your web platform or app works seamlessly across various devices, adapting to various screen sizes, including desktops, tablets, and smartphones, and increasing your reach and accessibility. Adopting a mobile-first approach, we focus on progressive UX buildup, touch-friendliness, and cross-device consistency by prioritizing dynamic values. Leverage faster load times and smoother interactions, keeping your user in mind.

Become SEO-friendly

If SEO optimization and search engine work matters for your product, we engage server-side rendering, which is the most efficient technology in the realm of SPA to support robot crawling. We use SPA but we can render it on the server. Get better search engine rankings, improving your project visibility in search results.

Scale naturally

Well-structured front-end code makes it easier to scale your product or application as your business grows, allowing for the addition of new features and content without major disruptions. To achieve this, we employ design patterns for competent code to make it easier for developers to work with it in the future.

Our Process

Wireframing and Design

We create wireframes or mockups of the user interface to visualize the layout, structure, and content placement. After you approve them, we develop the visual design, including the selection of colors, typography, images, and other design elements. You will get high-fidelity mockups or prototypes, followed by full UI/UX app design.

Setup CI/CD pipeline

Implementing a CI/CD pipeline automates code management, quality checks, and deployments. We choose a version control system, set up a CI server (e.g., Jenkins, Travis CI, GitHub Actions), and create automated deployment pipelines for staging and production. Rollback mechanisms are included for deployment failures.

UI Development

Implementing interactivity and functionality using JavaScript and front-end frameworks depending on the solution in question. Ensuring the UI complies with web accessibility standards, such as WCAG (Web Content Accessibility Guidelines), by providing proper HTML structure, alt text for images, and keyboard navigation.

Connect Backend

Integrating appropriate backend solution -CMS, API, Low Code or No Code Platforms, Serverless or Customly build backend based on requirements of the project.

Performance Optimization

Optimizing the front-end code, images, and assets to improve page load times and overall performance. This process involves code minification, image compression, and lazy loading.

Cross-Browser and Cross-Device Testing

We’re testing the front-end on various web browsers and across different devices (desktop, tablet, smartphone) to ensure consistent functionality, compatibility and appearance. Checking for responsiveness, identifying and fixing any bugs or issues, and making sure the ready solution aligns with the project goals and objectives.


Finally, we prepare the front-end code for deployment to a web server or hosting environment. Ensuring that all files and assets are properly configured and optimized for production.

Monitoring and Maintenance

Continuously monitoring the front-end performance and user feedback after launch. We make updates, fixes, and improvements as needed to address any issues or changes in requirements, if you have any.

Questions You May Have

What is the best language for front-end development?

There is no single “best” language for front-end web development services as different languages are suited for different purposes and have their own strengths and weaknesses.

At Devox Software, we use the most popular ones like JavaScript, HTML, and more.

Why is front-end needed?

Front-end development is needed to create the user interface and user experience of a website or app. The front-end refers to the part of a website or application that the user interacts with directly. This includes the layout, design, and functionality of the user interface, such as buttons, forms, menus, and other visual elements.

The front-end is important since it directly affects the user experience of a website or application. A well-designed and functional front end can make a website or application more user-friendly and easier to use, leading to higher user satisfaction and engagement.

What is more important: front-end or back-end?

Both front-end and back-end development are equally important for building a successful website or application. They are complementary and work together to create a complete, functional system.

Front-end developer services focus on creating the user interface and user experience of a website or application. It involves using HTML, CSS, and JavaScript to create a visually appealing and interactive user interface that is optimized for different devices and screen sizes.

On the other hand, back-end development concentrates on the server-side of a website or application. It entails developing the database architecture, logic, and algorithms that underpin the front end. This involves handling user data and transactions and building dynamic web sites using computer languages like Java,.NET, or PHP.

What frameworks do you choose for front-end development?

We mostly use React, Angular, and Vue.js.

Why choose Angular for front-end development?

There are the following reasons:

  • Сomponent-based architecture with reusable components
  • Using two-way data binding to reduce the amount of code you write
  • Mobile-first approach 
  • Easy-to-write template syntax
  • Large community of active developers
  • Regular updates by the Google developers’ team
