Please provide a spreadsheet of the average, senior, junior, intermediate hourly salary of tech / data freelancers developers by languages

Hello! Thanks for asking Wonder for a spreadsheet of the average, senior, junior, and intermediate hourly salary of tech / data freelancers developers by languages. In short, the most commonly quoted hourly rates for tech/data developers were £18.70 (median), £49.19 (high), and £10.96 (low). The highest average hourly rate was £55.00 for Android developers. I have provided the requested data for hourly rates for freelance developers by language in the attached spreadsheet, as requested. Below, please find an overview of my research, along with my methodology. METHODOLOGY / OVERVIEW
I began by doing some general searches, as well as searching freelance portals such as Upwork, to find actual freelance rates. It quickly became apparent that finding figures for Europe would be extremely difficult as the rates vary by country. Finding data for every European country to triangulate overall averages would be outside the scope of a single Wonder request. Therefore, I chose to focus on one country, England, in order to provide the most consistent figures possible.

The website IT JobsWatch proved helpful in this regard. This website shows contract (freelance) pay benchmarking statistics. The first table on each page shows the benchmarking data, while the following table shows statistics based on contract job vacancies with that job title and skill set. The benchmarking rates are consistently higher, and I have used those to populate your spreadsheet where that data was complete. However, in many cases, daily rates are provided more often than hourly rates. In those cases, if more complete hourly rate data is available in the job vacancy table, I have used that information to populate your spreadsheet. For many roles, the contract job vacancy rates are consistently the same across languages, which is likely because the roles require a similar set of language skills. Because of this factor, I have added columns for average, low, and high daily rates to offer a more complete picture.

The website provides a median rate, which I have used to show the average and intermediate hourly rates. Then it shows 10th percentile and 90th percentile rates, which I have used to show the estimated junior and senior pay rates, respectively.

In many cases, the specific sub-specialties, such as Node or React under JavaScript, were not called out separately, or if they were, they showed the same rates as the primary role. For instance, all the sub-specialties for PHP were listed individually, but they all showed the same hourly rates. I suspect this is because professionals who work as PHP developers work in all those sub-specialties and have a single rate for their work. In those cases, I have provided one figure for all sub-specialties. If I could not find or triangulate a relevant figure for a specific job or job level, I've entered N/A. In the case of the Lead position in your spreadsheet, I consistently found little or no data for that position. When it was available, it was usually offered as a daily rate, rather than an hourly. Occasionally, I was able to find separate daily rates for lead, senior, and junior positions, and I have noted those, where applicable.

All sources are included in the spreadsheet.

SUMMARY To sum up, the highest paid developers appear to be Android developers at £55.00 per hour. The most commonly quoted hourly rates for tech/data developers were £18.70 (median), £49.19 (high), and £10.96 (low). I have provided the data requested in the provided spreadsheet.
