With more than 20 million developers worldwide, it is interesting to take a look at their distribution by technology and seniority. So we used LinkedIn (a network of 630 million members) to find out how many Java, JavaScript, Ruby on Rails, Python and PHP developers there are in the US, UK, Germany, the Netherlands and Ukraine.


We also analyzed the distribution of developers by seniority in each country. In addition, we used Upwork (a platform with 17 million members) to determine the number of developers and to compare them with the results of our LinkedIn research.

Without much analysis, it can be immediately determined that Ukraine occupies one of the leading positions in various technologies and even surpasses the USA in terms of the number of PHP developers. No wonder that the market for IT specialists in Ukraine is now one of the most progressive in Eastern Europe.

185K software developers work in more than 4000 IT companies in Ukraine. And 20% of the world's leading companies have already opened offices there.

Read on to learn more about the number of developers by technology and experience in Ukraine and other countries.

About the method

For the creation of this article we have the professional Recruiter Tool from LinkedIn used. This gave us access to specific search options such as details on technical specializations and years of work experience.

We have some programming languages ​​that are popular according to the TIOBE index, such as Java, JavaScript, Ruby on Rails, Python and PHP selected.

Then we looked at the total number of programmers for each technology in each country we studied USA, UK, Germany, the Netherlands and Ukraine.

We then analyzed how many developers for each technology junior (0-3 years of experience), middle (3–6 years of experience) and Senior (6+ years of experience) are.

We also used Upwork to provide alternative dates on the number of Java, JavaScript, Ruby on Rails, Python, JavaScript and PHP Developers in the United States, Great Britain, Germany, the Netherlands and Of Ukraine to find.

* The number of developers by technology and seniority can be seen more as an indicator of general trends in the talent markets and may be incomplete as it is only based on data from LinkedIn

Upwork research on the number of developers by technology

* We used Upwork to calculate the number of developers in each country, so the data may be incomplete and should be viewed as a general guide.

We also looked at Upwork - an international platform with 12 million freelance professionals.

We counted the number of developers in each studied country - the US, UK, Ukraine, Germany, the Netherlands - and analyzed the technology distribution in each country.

Although the number of developers differs greatly, the distributions are similar to those from the LinkedIn data.

Conclusions

Our extensive research with data from LinkedIn and Upwork led to several interesting conclusions:

  • A bigger population doesn't necessarily mean a higher number of developers - Ukraine has more PHP software developers than the US. There are 9,000 PHP developers, in the USA, however, only 7,000 PHP software developers.
  • With 68 million Population is Britain's population is greater than that of Ukraine 43 million inhabitants. Nevertheless, Ukraine leads in the number of software developers in several technologies. There are 3,000 Python developers in the Ukraine and 2,000 Python engineers in the UK. Working on JavaScript 8,000 with this knowledge in Ukraine and 5,000 in the UK; In Ukraine you can find 1,000 Ruby on Rails developers, in the UK only around 700 Ruby on Rails engineers.
  • Although almost five times fewer people live in the Netherlands than in Germany, there is a comparable number of software engineers in both countries. In the Netherlands and Germany around work 6,000 Java developers and almost 3,000 JavaScript Software engineers. In the Netherlands there is almost 3,000 PHP programmers and in Germany 2,000 PHP developers.
  • With regard to seniority, it can be seen that in most countries senior engineers make up the majority of engineers, which indicates an unequal distribution by seniority. The only exception is Ukraine - the distribution by seniority is relatively even. The total number of JavaScript developers in Ukraine is 8 000, of which 2 junior, 3,000 middle and 3,000 senior JavaScript developers are. This trend indicates a diverse market for technology talent in Ukraine, where it is relatively easy to find developers of various seniority levels.
