As always, business strives to reach as large an audience as possible. In our digital era, every device is a channel of interaction between business and client. Since there are so many types of devices, businesses have to develop and maintain a whole host of client-server applications. Each application requires personalized content that needs to be managed. This situation led to the birth of content management systems (CMS) and a headless CMS in particular.

Every software runs into technical debt sooner or later. If developers keep it under control and manage to pay it off on time, there is nothing to be afraid of. If they don’t, the situation can grow out of control making further development extremely hard or even impossible.

Today we’ll talk about one of the most popular practices for dealing with technical debt — refactoring.

Technical debt: definition

According to Wikipedia, technical debt is “a concept in software development that reflects the implied cost of additional rework caused by choosing an easy (limited) solution now instead of using a better approach that would take longer.” …

It’s hard to count all the types of screens and displays that exist now. The number of their sizes and configurations is truly huge, and people use them for various purposes.

The more screens people use, the better software should adapt to them. The quality and detail of the visual elements should stay the same across all user’s devices, from a smartphone to a high-resolution monitor. No matter if it’s a complex website with lots of screens, animations, and pictures or if it’s just a simple landing page with one button — everything must look good.

Implementing your idea into reality requires a lot of effort. You should write a business plan, think over all the functionality you want the app to perform, take into account some marketing strategies, analyze your competitors and a target audience, and then turn to the developers.

Many digital agencies that work with web and mobile development focus only on the tech side of outsourcing projects. They just listen to the requirements, take the task, and do whatever they’re told to do. …

Today’s smartphones can do almost everything! You can professionally edit photos and videos, listen to music, play games with amazing graphics, and keep track of your health. Millions of apps with an enormous range of functions are available to everyone in the various app stores.

Since so many apps provide people with such vast functionality, competition is intense and customers can be really picky. To grab the attention of your target audience, you need to highlight every possible advantage of your product and make it shine against your rivals.

A very important stage in this process is your app’s page in the digital store. When a user is thinking about downloading an app onto their phone, this page is where they must go to learn more about it. Since Google Play and the Apple App Store are the most popular digital stores for mobile apps, most marketing efforts are focused there. However, these two services require different approaches. …

When a developer writes code for hours without a break, unnoticed mistakes will appear that can ruin the program in the end. Because of this, development without a proper ongoing review process can hardly be imagined.

One of the most useful and efficient ways to organize the review process is to use cross-review. While this review method might be unfamiliar to some people, it is popular among development teams around the world.

Here we’ll explain how this model helps development and why it has become so well-known.

What is it?

To put it simply, cross-review is a technique where all the members of the team check each other’s code before it passes on to testing and then to release. Organizing the review process in this way helps the team speed up their development and helps them communicate with each other more comfortably. …

It’s impossible to imagine our lives without budget planning. We have to buy a lot of things, from food to entertainment, and if our expenses aren’t well managed, it’s easy to lose control over them and start spending too much. The same goes for software development. If you want to create a new app, managing your financial investment is one of the most important parts of the whole process.

Why is it so hard to plan it right? Keep reading to find out!

What is a budget and how to plan it

The answer may seem easy: A budget is money. Well, that’s true, but an explanation like that is uselessly vague and superficial. If we take a look under the hood, budgeting for software development is a much more complex concept than you could imagine. …

Development is the core concept of product creation. Basically, development is product creation. Every point of UI/UX design, every basic and additional function is implemented with the help of code, both in web and mobile apps. This process is complex and requires proper control, so that the final product will be finished on time with minimum bugs and maximum profit.

How to do it? Well, we’re here to help with five tips for nearly flawless development.

Set clear goals

Teams suffer if there is uncertainty during development. This happens if no clear goals are set at the very start of the project. Developers are just given a task — and that’s it. They have no idea why their piece of code is important or why they should write it at all. …

Once an idea has proven to be viable and a clickable prototype is ready, it’s time to start thinking about what users should see in the future app — a beautiful and functional UI/UX (user interface/user experience) design. While no crucial decisions are typically made at this stage, the design still can play a role in the product’s fate.

Why design is a double-edged sword

Many philosophical perspectives suggest that everything in this world consists of two opposing aspects, and design fits this duality well. Why? Because software design is simultaneously both an easy and a difficult process. What’s easy about it?

An MVP (minimum viable product) significantly increases the chances for your product to win engagement from real customers and break into the market. You just need to create a bare bones version of the product, show it to consumers, clean up its failures, and most importantly, discover what features your customers truly value. Sounds easy, right?

But building your MVP carries some challenges. What are the most common mistakes? Keep reading to find out!

MVP — What’s it all about?

Generally, an MVP is the first version of your product, consisting of just the core features. According to Eric Ries, author of the Lean Startup methodology, an MVP is “that version of a new product which allows a team to collect the maximum amount of validated learning about customers with the least effort”. …
