I...I....
And that's your problem. Not a single thing about them. It should read something like this...
I noticed you've been working on innovating in X industry, and I've noticed recently that many folks are moving in X direction. Are you planning on moving in this direction to?
I've recently done a, b, and c. By leveraging b and c, I can help you achieve X. a is note worthy because, while not directly related to x, it shows I have skill f.
I'm looking for jr developer positions that allow me to grow, and projects a, b, and c will help you achieve x (faster, better, more completely, etc)....
Your pitches need to be about how you can help them and less about you. I've sent emails that basically said, "Your industry is heading in x direction, here's what I think about that. Oh, by the way I'm at least good enough to do fizz buzz" and gotten fairly positive responses out of that.
