Dude, your english is not great. I am Mexican myself and believe it or not, that's a big show stopper.
I applied to 37Signals back in 2008 or 2009 and my english was so bad that they won't even bother to reply (And they wrote a blog post shortly that they wouldn't even respond to poor communicators :P)
That wouldn't explain why the holagus guys wouldn't hire you, tho ;)
This is my advice:
1. Forget about going to a job you hate. I'm 36 right now and I wasted almost ten years of my life on boring jobs and now I wish I wouldn't. The tech sector has an age bias and the older you are you're less likely to get hired. True story.
2. Get involved in Mexico's tech community. Build things and show them to people. Go to conferences.
3. Work in a startup with coders that are way, and I mean way, better than you. If you don't live in a tech hub move to CDMX or GDL. I know that in GDL there are startups which are hiring pretty much everybody.
4. Don't be an asshole. I'm not saying that you are. But if you give that impression, people may not want to hire you. Please don't brag about how you were programming at 10 (we all were)
Lastly, I know some people in mx's and latam tech community, maybe I can help you get connected. Ping me at @soska.
-- And yes I know my english sucks too. But it used to be worse.
Learning to better communicate in written English, is huge. Event though I'm a native English speaker, I'd say written English has been the main thing holding back my career.
Improving your business communication skills goes a long way. I'm still terrible, but every improvement I've made has lead to positive outcomes in performance reviews.
Your coding skills become far more valuable if you have other skills to compliments them. If you can code and interact with clients you'll be a more attractive hire.
Most of the media I consume (movies, series, articles, books, podcast) have been in English for the past ~10 years and it did not help much my communication abilities. I actually have a vast vocabulary (sometimes people mock me for using fancy words) but I still struggle writing "natural" english because, for the most part, I still have to translate from Spanish (or Mexican, rather :P) to English in real time.
As for spoken communication, what I needed was a boost of confidence. In my last job I always avoided talking to people because I was too self-conscious of my accent and constant pauses for real-time-translating. Then, one day, a friend noticed it and said to me: "Dude, don't worry about your accent. I live in Manhattan, everybody has an accent here and it's no big deal." And I was like, "yeah". And just like that I started speaking more and slowly became better at it.
I don't know about him but, when you have a certain skill level in English, the best way for me to improve is by reading tons of books in English. That's the way you learn vocabulary/expressions you usually don't use and how to use them properly.
