Done once, lasts longer

Plan while developing a web application

Web development is a smart business strategy. With current technologies, it’s a common practice to share the backend infrastructure across multiple platforms. Thanks to that, once prepared, business logic can power web applications, mobile versions and even support wearable devices like watches by sharing and synchronizing critical data across cloud API.

Proven product workflow

What does web app development look like?

  • 1

    Workshops and Ideation

    Taking time to polish up the value proposition and understand the user is necessary to ensure a solid foundation of the business concept

  • 2

    Product Design

    Our designers refine the wireframes and translate the rest of the user stories into a visual interface adopting a user-first approach

  • 3

    Usability Testing

    The concept and prototype are tested on suitable personas gathering feedback for UX and UI adjustments

  • 4


    We combine test-driven development (TDD) and agile approach to ensure a smooth development process that will quickly react to market needs

  • 5


    We always observe the product’s performance - technologies get outdated, security threats need to be mitigated, and your solution has to be ready to face huge numbers of users

  • 6

    Further Development

    Seeing real users interact with the product makes it easier to plan the next steps of business development, prioritize new features and build a long term roadmap

Optimal technology stack

Choosing the right web development technology

SDH developers navigate the quickly changing technology industry every day and are ready to dive deep into each product's needs and suggest the correct development tools. We use top technologies to ensure the highest quality of the final product and be adaptable to dynamic changes during the development.

Web development languages we use:

  • Ruby (Ruby on Rails)

  • JavaScript (ReactJS, NodeJS, Angular)

  • Python

Web development tools we use:

  • GitHub

  • Visual Studio Code

  • CircleCI

Efficiency comes with experience

Quality ensuring development practices

  • Pull Requests are part of the code review stage during the development. They provide more stable code, good communication between developers and seamless, faster testing.

  • Static Code Analysis helps find weaknesses in the code and means analyzing the code without executing it to find bugs as soon as possible.

  • Automated tests enable higher test coverage, save time and guarantee faster feedback that leads to overall more effective development.

  • Communication – thanks to the implementation of Scrum methodology and daily meetings, the whole team collaborates through shared understanding during the development, and everyone can react quickly if problems arise.

Work with the best

What services should a good web development company provide

Streamlined, clear design

is essential for the user, but also in further development. Good UI and UX practices and the right tools ensure seamless communication between the developers and designers and are the base of every project.

Accessibility standards

ensure that the products are designed with an adequate level of accessibility in line with WCAG 2.0 recommendations to prevent discrimination and make the web app open to everyone.

Transparent procedures

and ongoing insight into the project’s progress, meaning budget used, time and resources management, should be provided to guarantee successful collaboration and mutual trust between the client and the web development company.

Fast and accurate QA

including cross-browser and cross-platform testing, to get maximum user satisfaction no matter the web browser or the device they’re using. High-quality QA is crucial for proper web app development.

App performance

management is necessary to ensure that the app works properly. Cloud apps give a lot of freedom to scale applications horizontally and handle thousands of users and guarantee optimal performance. Cloud infrastructure should be set up by GCP & AWS certified developers experienced with database design and know what it takes to scale them.

App maintenance

is crucial for keeping users satisfied, and it’s no secret that bad code is hard to maintain. Therefore code should be well written and well tested, using industries’ best standards and the most popular and battle-tested libraries. Well done maintenance covers new features, updates for new hardware/software, licenses and more.
