A day in our training

Live coding

Developers will be introduced to new concepts with presentations and also live examples. With live coding we can enhance interactions between trainees and instructors and provide tailor-made examples to trainees’ queries.

Pair Programming

By working in pairs developers have to explain to their partners what they do and how, rather than just doing it. Explaining is a great way to learn and consolidate the new skills. Pair programming also increases motivation and productivity.


Our experienced instructors will give developers individual feedback whilst developers are coding. Instructors will guide and mentor them to think of the best way to solve a given problem. Groups of 10 developers for 1 instructor on average.


We are strong believers in learning by doing, and so we want developers to code as much as possible, so they can make mistakes in a safe environment. You will have time to practise everything we explain during the training.

Return of investment

If you own a business

How much are you paying to learn as you go? Let’s say you spend 16 hours (2 days) training a team of 10 engineers. In the next year, these engineers will put in approximately 20,000 hours of work for your company. If training your developers results in only a 1% performance improvement, your company will gain the equivalent of 200 hours of work as the result of spending 2 days in training.

If you are a developer

How long is it taking to learn as you go? How long are you willing to wait for that awesome job in an awesome company? Learning cutting-edge JavaScript will make you a developer in demand and it will put you on top of the market. Investing in your career is a great investment. React is creative and fun, unleash its full power and become an amazing JS developer.
