First, don't think that you're behind because you have a degree in ME and not CS (I too have a ME degree, and that's never stopped me). So, be excited! Second, I would suggest maybe not going the code bootcamp route. Sometimes they're really good immersion training in web development, but sometimes they can end up basically as developer puppy mills. Instead, you may want to consider finding ways to use your mechanical engineering experience to find things code might make better. Cross-disciplinary work like that is really valuable.
