Online Course JavaScript: Professional Web Interface Development

This course is designed for those who want to change careers and become highly paid professionals. It’s suitable for working people who have little free time.

Why this course is professional

In this course, you will learn to create real projects, with the same level of complexity as in the industry. And you will do them correctly, so that after the course you can deliver high-quality results that companies are willing to pay for.

To achieve such training quality, we use the professional triad "criteria-projects-mentors":

MentorsMentors, who are professional developers, check your projects for compliance with quality criteria.

Quality criteriaWe develop professional quality criteria together with companies and the professional community.

Real projectsDuring the course, you complete real projects.

What’s the difference from exercises?

It’s exactly in this triad. In exercises, you study the basic language constructions, while on the professional course you learn techniques and methods for solving real-world professional tasks.

Is This Course Right for You?

We Teach You to Do Things Right

Mentors — experienced professionals working in the industry

Mentor

We believe that students should receive feedback from experienced specialists who are currently working in the market, solving modern problems, and using up-to-date approaches and tools.

To select such specialists, we built a unique recruitment and filtering system.

Together with your mentor, you will develop a project in an ecosystem familiar to professionals. The workflow is very similar to real development in large companies.

Mentor selection process

  1. Formal requirements

    We check where the mentor candidate worked, what experience they have, and also review their code.

  2. Interview

    We conduct a one-hour interview to assess subject knowledge, the ability to explain clearly, and other personal qualities.

  3. Regular feedback

    Candidates who pass the interview start working with students. This is just the beginning of their mentoring journey. After each course, we collect feedback that helps mentors improve.

Working with a mentor

During the course, a mentor will accompany you. They will review your code, check your assignments, answer questions, and share their expertise.

Hi. My last product block is misaligned, I tried everything. Can you take a look?
Let’s call today and figure it out together.
Voice consultation with a mentor

Detailed feedback

Code review is a common practice in large companies when a more experienced developer checks the code of a less experienced one. Most of the feedback you’ll receive from your mentor will be in the form of code reviews.

Voice consultations

When code review isn’t enough, mentors use voice consultations, often with screen sharing. During these sessions, they analyze complex issues or demonstrate advanced techniques.

Training Project

Using the example of the course's training project, tasks that a developer should be able to solve are explored. You solve similar tasks in your personal projects to reinforce your skills.

All projects are already coded. During the course, you will focus only on programming.

Training project 'Code & Magic'

"Code & Magic"

A demo page of the platformer game "Code & Magic", where you can play the game, customize the appearance of your character in a special window, buy artifacts that help in the game, and see similar characters of other players.

Personal Projects

During the course, you will work on the project "Kekstagram". In individual learning, an additional project "Keksobooking" will be available.

Personal project 'Kekstagram'

"Kekstagram"

A photo-sharing service. Users can upload their own photos, edit them, and apply filters. You can also view photos from other users, like them, and leave comments.

Personal project 'Keksobooking'

"Keksobooking"

A real estate listing service in Tokyo. Users share information about their property, upload photos, and mark the address on the city map. You can also view listings posted by other users.

Company Reviews

We have long established ourselves in the professional community. Both developers and large companies know us and our graduates. Here are some reviews from companies about our courses and graduates.

Overall, the training program at the Academy is well-structured for a start. It helps prepare a universal professional who can work effectively both in an agency and in a large product company. If someone defends their project 100%, it shows that they are capable of learning, motivated, and have the personal qualities needed for future work. After that, everything depends on their activity and ability to prove their skills in practice.

As a mentor in the courses and a former student, I know the Academy’s quality standards and how the work is organized. Everything is as close to real conditions as possible — Git version control is used, projects are divided into stages (iterations), mandatory code review by mentors, and strict deadlines. Much attention is paid to accessibility, which is beneficial for the entire industry.

At Avito, we don’t have layout designers, only frontend developers of different levels. To join us as a junior developer, a person must have certain skills: confident knowledge of HTML, CSS, and JavaScript, understanding how the browser works, knowledge of cross-browser compatibility, API, DOM, and other key basics. In addition, we value responsibility, teamwork, the desire to grow, and initiative.

When it comes to layout and creating web pages, our team is very attentive to semantic markup, the ability to write clean CSS, and systematic thinking in a developer. Pages should not only look good for users but also load quickly, be well-structured, and of course, convenient for teamwork. With the volume of projects we have, this is very important.

We also value an understanding of accessibility principles, since caring about people who will use the interface is simply good practice. A person joining our team should not be afraid to tackle unfamiliar tasks, look for creative solutions, and take responsibility.

In this sense, the Academy’s approach to training seems adequate: code reviews from experienced developers prepare students well for work. It is especially valuable that all project work is done through Git — in our company, all work also goes through mandatory reviews.

Currently, a graduate of the Academy, Pavel, works in our team, and I am satisfied with him. The necessary basic skills, understanding of semantics, working with clean CSS — all of this is at a good level. As for JavaScript — he quickly adapts if he has done something similar before. He was ready to get to work right away.

Sometimes, when a new junior developer joins, mentoring has to cover even the smallest details. With Pavel, integration into the team was almost effortless.

As a manager, I don’t care about certificates and diplomas; I look at the code a person writes, what drives them to work in this field, and why they chose frontend. If I see that a person is self-developing, taking courses, and determined — for me, that is a good indicator of their motivation.

Employees who completed the courses said that the material in the lectures and assignments was presented clearly and engagingly. They also noted that after the training, thinking shifted to better understand the specifics of the language, which helps in their work. The training required a lot of time, but it was worth it.

For our company’s tasks, the training program covers all the necessary fundamentals and even some tricks. That’s why we send both experienced developers to the Academy to structure their knowledge and beginners to bring them up to the required level.
