He graduated with BSc First Class Honours in Electronic Engineering at City University, London in 1981 taking various modules which included Computer Engineering. Later in 1986, he completed his MSc in Information Technology where he finished various assignments which included two integrated circuit designs and a compiler. He worked as a Telecommunication Engineer at Telekom Malaysia Berhad, from 1981 to 2009 with breaks to complete his MSc and study leave at Nanyang Technological University from 1990 to 1993 where he also worked as a lecturer teaching Assembler and Loader. His main research as well as registered PhD topic was Computer Architecture. From 2009 he worked as a Senior Lecturer at University Malaysia Sabah for the Computer Engineering Department teaching Computer Architecture. Retiring from UMS in 2021 as an Associate Professor in the renamed Electronic Engineering(Computer) program.His was awarded the ASDK by the State Government of Sabah for contribution to Sabah. He had completed many Telecommunication projects which include solar powered rural communication, and transfered to all the various engineering departments. He had published conference papers and journals which include indexed publishers. He has self published only in eBooks at both Smashwords and Apple Books using research materials that include his own papers either published by other publishers or not.He has filed 6 patents at UKIPO, USPTO and MYIPO, with a few of them granted with titles such as Zero Energy Transportation System, Zero Aerodynamic Drag Vehicles, An Optimum Hybrid Vehicle, Optimum Collision Damage Reduction System, Imperfect Perpetual Motion Heat Engine and Simplest Word-size Scalable Processor. Despite their controversial topics Zero Aerodynamic Drag Vehicles and Imperfect Perpetual Motion Heat Engine were granted by UKIPO. None had been granted b USPTO but the reasons for rejection are just absurd so need to proceed to the Supreme Court of the USA to get approval.He is active in self publishing in eBooks such as Smashwords and Blogs. eBooks allow more structured and thorough reading but Blogs and discussion groups allow instant backup of articles and views on certain topics which had come handy for inclusion in the eBooks.The author may seem to cover a very wide topics but they were actually part of his expertise and hobby. Road Traffic enginneering is just an adaptation of Telecommunication Engineering and research results were actually published in conferences. Mechanical Engineering topics were just basic physics subjects that are part of the basic course in an Engineering Course and so are Management Courses, which should include an understanding of economics.view less
