welcome, I have started this website to introduce myself to others including employers, and to connect with those amazing people like you who share similar interests. Also, to show my works and some of my achievements as well as share knowledge and inspiration....

I am a passionate engineer licensed by Saudi Council of Engineers with about 8 years of experience including 3 years of industrial work (ABB Company and Saudi electricity Company), 5 years of academic work as a researcher at the most reputed university in South Korea [#1 in ranking of private universities among 203 universities and 127 community colleges in South Korea and top 100 worldwide QS).

Through my work responsibilities and tasks in electrical industry, I have grasped a very good experience in the field of project engineering by managing, preparing, planning, scheduling, coordinating and monitoring the assigned engineering projects as well as monitoring compliance to applicable codes, practices, QA/QC policies, performance standards and specifications and safety regulations.

In addition, I have acquired an extensive experience in the technical activities of electrical equipments, electrical network designing, planning, simulation and optimization using PSS®E, studying and forecasting of electrical loads, electrical generation, transmission, distribution systems and designing of high voltage substations (110 - 132) KV by preparing work scopes, drawings and layouts, suggesting the best geological locations and coordinating with other departments, specifying standards and the required equipments.

Moreover, through my post graduate studies in South Korea in the area of Electrical and Computer Engineering, I gained an excellent skills in scientific research and problem solving, and grew deep experiences and high professional skills in the area of Signal Processing and Artificial Intelligence (Wireless Communications, Machine Learning, Deep Learning, Data Mining and HCI).

Such skills are essential to prepare engineers and researchers to the next level industrial challenges and creating innovative solutions to a number of important fields such as Smart Grids, Smart Cities, Wireless Networks, Machine Learning, Medical Devices, Automation and IoT).

A glimpse

Helloo aliens:) I am Waleed, a passionate engineer from planet Earth, born in the 80's, seeking to improve the life quality of creatures living on my planet (I may participate to your planet too).... I love reading and researching and my best joys is the fraction of moment I go beyond the time and space and forget everything around me and shout ... "Aha!". It might be a bit weird for an engineer who's passionate about technology to dislike most of current social media apps, but it would makes sense once looked deeper into the negative impact of such apps, this is why all of my social accounts almost obsolete (I really miss MSN Messenger tho). I am so famous among books in my library, and among tools of my personal lab, and I love writing but I am always in fight with my lovely quill as she gets jealous of my keyboard. Arabic is my soulmate but unfortunately sometimes I cheat her with English as it's the most spoken language nowadays. I consider my self a modern man, but my soul seems to be classic and stuck in the oldies. "Somewhere in Time" is one of my favorite movies and "Quantum Leap" is my beloved TV series. I have serious problems caused by my extreme ambitious and perserverance, they both get me always in troubles but somehow bring a sweet complications in my life!. I believe the global warming is a natural process of Earth abused by politicians, and whether the Earth is a flat or a globe, the conspiracy is not a theory it is a fact!. Throughout my life, I have realized that the life isn't always fair and this is why Hell and Heaven had to exist..!

"The most beautiful people we have known are those who have known defeat, known suffering, known struggle, known loss, and have found their way out of those depths. Character cannot be developed in ease and quiet. Only through experience of trial and suffering can the soul be strengthened, ambition inspired, and success achieved..!"
