I have created many apps throughout my career. Some apps, such as the Finxter Python learning app, have reached millions of users over the years.

While I’m not a professional web designer (by education), I was taught the hard way (by trial and error) that there are some crucial and timeless skills you need to master as a User Interface developer no matter what.

This list of 20 tips is my best-of compilation. So, without further ado, let’s dive right in! πŸ‘‡

Skill 1: HTML/CSS

HTML and CSS are the building blocks of any website, and a must-have for any UI developer.

HTML is the structural markup language used to create webpages, while CSS is the styling language used to make them look attractive.

UI developers need to understand the principles of user experience and dive deep into users’ emotions so they can create enjoyable and fun experiences.

Skill 7: Cross-Browser Compatibility

Cross-browser compatibility is the ability of a website or web application to work properly across multiple types of web browsers.

UI developers need to ensure that their websites and applications look and function properly on all types of browsers.

Skill 8: Version Control

Skill 10: Testing/QA

Testing and Quality Assurance are processes used to ensure that a website or web application is functioning correctly before it is released. UI developers need to be able to test their work and ensure that it meets the specified requirements.

Testing is often not done correctly or follows too strict rules. In my world, when I create apps, I just play with them, pressing any button and inputting all kinds of stupid things to test my app. This has brought to light many more errors than standard unit tests.

Skill 11: Building User Interfaces with Frameworks

Frameworks are used to simplify the process of building user interfaces. UI developers need to be familiar with the most popular frameworks in order to create modern and efficient user interfaces.

Skill 12: Accessibility and Usability

Accessibility and usability are two important aspects of user interface design. In fact, there’s a huge megatrend towards creating more accessible user interfaces — often, they are legally required!

It’s a big growth market — unbelievable, isn’t it? πŸ˜‰

UI developers need to be able to design interfaces that are both accessible and usable to provide the best user experience.

Skill 13: Interaction Design

Interaction design is the process of creating user interactions that are both intuitive and efficient. UI developers need to be able to create interactions that are easy to use and don’t require a lot of effort from the user.

Skill 14: Web Design Principles

Web design principles are the fundamental rules that should be followed when designing websites and web applications. UI developers need to understand these principles to create attractive and effective interfaces.

The Art of Clean Code

Most software developers waste thousands of hours working with overly complex code. The eight core principles in The Art of Clean Coding will teach you how to write clear, maintainable code without compromising functionality. The book’s guiding principle is simplicity: reduce and simplify, then reinvest energy in the important parts to save you countless hours and ease the often onerous task of code maintenance.

  1. Concentrate on the important stuff with the 80/20 principle — focus on the 20% of your code that matters most
  2. Avoid coding in isolation: create a minimum viable product to get early feedback
  3. Write code cleanly and simply to eliminate clutter 
  4. Avoid premature optimization that risks over-complicating code 
  5. Balance your goals, capacity, and feedback to achieve the productive state of Flow
  6. Apply the Do One Thing Well philosophy to vastly improve functionality
  7. Design efficient user interfaces with the Less is More principle
  8. Tie your new skills together into one unifying principle: Focus

The Python-based The Art of Clean Coding is suitable for programmers at any level, with ideas presented in a language-agnostic manner.
