In your top paragraph, you employ the word "stuff" - twice. Using vague, possibly meaningless, placeholders for what could be significant content fails your goal of drawing attention to your actual skills.
Speaking in whole, grammatically correct sentences is a minimum standard. English may not be your milk tongue, but that won't be forgiven since you have all the time in the world to formulate your thoughts into complete, coherent statements in whatever language you choose to advertise yourself via a web page. You misspelled "programming"!?
The use of color highlights for special terms and emblem-like "lozenges" is visually distracting. Are they links...buttons? No, seemingly they are just misunderstandings about basic UI idioms.
Needs work.
