I think folks reading this are seeing that you are too technical and lack of business acumen (while maybe not true).
For the work that you have done in each company they may be interested in the results of you creating these not that you created those. Did you ever find out what was the impact of your software development on the actual business?
Make sure to include numbers, people love data and lifts in sales, reach, clicks, awareness, revenue, etc.
You can save so much space by summarizing your language skills elsewhere instead of in each company. It also sounds redundant to say Used X, Y, Z because of course you needed to Use some programming language to achieve that. Group all of those elsewhere for those that you feel you are an expert with.
Best of luck!
