Custom web app

What is it?

A web application is an interactive program that performs functions over the internet without requiring users to install it on their devices. By using progressive web applications, developers can create apps that combine the ease of web apps with the seamless experience of a native application.

We can easily develop any web application to target your specific audience, retain them, and keep them engaged.

Custom web applications benefits

Incredible mobile experience
Web apps deliver an app-like experience in the browser without downloading an app. Plus, they create a rich, capable user experience, even when the user is offline.
Increased conversion rates
Due to their high user engagement, custom web apps can also increase conversion rates.
One development
Don’t bother building many platforms for different OSes and devices. Save money instead - web applications blur the line between websites and mobile apps.
Great performance
By cache site assets, you get a high-speed native mobile platform feel with many benefits of a web app in your browser
PWAs are great for moving web apps to mobile devices. The serverless architecture scales automatically as your user base or usage increases.
With Jamstack, your PWA can be hosted like any static site. Nothing minimizes hosting expenses better than serving static assets from the CDNs.

The Process

1. Setting up the clear project goals

During online meetings, we gather the project requirements and documentation and discuss them with you to ensure we understand them the same way. By learning what your business needs most to thrive, what your objectives are, and your expectations, we will stay focused on them during the whole project.

2. Tech stack matching, kickoff, and plan

Thanks to our expertise, we'll offer you a couple of technologies that will suit your interests and requirements best. The Project Manager and Development Team Leader create a backlog and roadmap for the project. They also set up a transparent work environment by giving you access to Slack workspace, Jira board, and Github repository to ensure you are always up to date with work progress.

3. Creating a web app design

If there is such a need, we cooperate with our design team with UI, UX, and product designers. According to your business goals, they plan and prepare research methodologies, mood boards, wireframes, prototypes, and high-fidelity designs for your new product. Each step will need to be approved by the client before the final project, the same as budget reestimation based on it.

4. Web development

We develop websites in a decoupled architecture based on our expertise and final design projects (delivered by our internal design team or the customer). In weekly or bi-weekly meetings, we present a product demo, update you on the time and budget and present the plan for the next sprint.

5. Testing, training, and launching

Testing is integral to the Bejamas approach in website and application development. Each test enables us to ensure that the systems are bug-free, meet client expectations and fulfill end users' functional and aesthetic needs. Before the launch, you can also expect training by accessing CMS and the demo environment. With the final live website, we provide you with all code documentation and style guide.

6. Afterproject relationship

Our team will be happy to stay with you, handling your feature requests and maintenance so that you can grow your business seamlessly. With us, you can develop your product further from design to development. After product release, your company can always count on additional research, support, and verification of the product.

Based on customers' feedback,
Bejamas guarantees:

Efficient communication
