Short biography for TEDX TALK and Marketing proposal

This is my first draft for my biography. I just wanted other opinions on it. Be as critical and rough as you want. Thanks!
Abdelrahman is an eighteen years old Egyptian high school student who has invented a new inexpensive and eco-friendly recycling method of construction and demolition wastes. He recently won the international concept project competition organized by Middle East Technical University. This was the first time for Arabian or Egyptian student to win at this environmental competition. Also, he was chosen to with his environmental project to represent Egypt in Intel science competition Arab world 2012 (ISC) in Dubai, UAE. Moreover, he joined a team of three persons who invented a new cancer detection method through handwriting analysis. They won the first place nationally in Intel Bibliotheca science and Engineering fair 2013 (Intel BASEF). More importantly, they won in Intel International science and engineering fair 2013 (Intel ISEF) in Arizona, USA. Also, they were the first Egyptian winners since eight years. In addition, he won in the Egyptian WRO 2012 (Egyptian world robotics Olympics) and represented Egypt and won in the Arabian WRO (Arabian world robotics Olympics). Besides, he represented Egypt in the Pan African Mathematical Olympics 2012 (PAMO) for the first time for Egypt. When you ask about Abdelrahman and you didn't find him doing a research or one of his science experiments in the science lab you will surely find him listening to one of his favorite sax concrete. He adored music and he is going to double major Material engineering with music major in the university

It's well written, few points, I would like to point out:

years old Egyptian high school student would better sound if you write "years old high school student from Egypt ..."

who has invented I feel "who invented" sounds better.

won the international concept project competition would be better as won the "International Concept Project" competition.

time for Arabian or Egyptian student to win at this environmental competition This was the first time any Arabian or Egyptian student had won this environmental competition.

chosen to with his environmental project chosen for his environmental project to represent...

three persons three people

they won in Intel International they won the Intel International...

First of all thanks so much for your attention for that piece of writing.After dpa amendments it would be in that form:

Abdelrahman Abdelmoniem is an eighteen years old high school student from Egypt who invented a new inexpensive and eco-friendly recycling method of construction and demolition wastes. He recently won a special recognition at the International Concept Project Competition organized by Middle East Technical University. This was the first time any Arabian or Egyptian student had won this environmental competition. Also, he was chosen for his environmental project to represent Egypt in Intel science competition Arab world 2012 (ISC) in Dubai, UAE. Moreover, he joined a team of three people who invented a new cancer detection method through handwriting analysis. They won the first place nationally in Intel Bibliotheca science and Engineering Fair 2013 (Intel BASEF). More importantly, they won the Intel International Science and Engineering Fair 2013 (Intel ISEF) in Arizona, USA. Also, they were the first Egyptian winners since eight years. In addition, he also won the Egyptian WRO 2012 (Egyptian World Robotics Olympics) and represented Egypt and won in the Arabian WRO (Arabian World Robotics Olympics). Besides, he represented Egypt in the Pan African Mathematical Olympics 2012 (PAMO) for the first time representing Egypt. When you ask about Abdelrahman and you didn't find him doing a research or one of his science experiments in the science lab, you will surely find him listening to one of his favorite sax concrete. He adored music and he is going to double major materials engineering with music major in university.

Don't hesitate to criticize it more that would be too great for me.

.... I feel it is better if you break up this line into two rather than making it too compact with too many ideas;
Abdelrahman is an eighteen year old high school student from Egypt. He invented an inexpensive eco-friendly recycling method of construction and demolition wastes.


This was the first time that an Arabian or Egyptian student won an award at this environmental competition.
