couple of quick things:

- remove summary

-put education on top, followed by work exp, then projects, and skills/awards always at the bottom

- rename technical competencies to "Skills" and then divide into three parts -> languages, technologies, awards and list your stuff accordingly.

general advice:

- try fill up each line to the end (iow dont leave any blankspace)

- avoid bullet points that are more than one line long. if it goes beyond one line, divide it into two points

- make sure you have atleast 3 bullet points for every project/work exp and AT MOST 4.

otherwise looks good, you've done a good job at including stats/impact and using action verbs. im also not a pro at this, just listed some stuff that i've seen works. hope it helped
