Portfolio

Throughout my short career thus far I have participated in several projects, either

academic, career oriented or private. For each project I have completed I have gained a

new experience and vast knowledge, the purpose of this document is to highlight the

various type work I have done, exposure, knowledge and experience gained. All work

represented here is work conducted entirely by myself or work I was in a position to

supervise, influence and present as a team effort.

I. Belgium Racing (10/2014-Present) Working with Belgium Racing as a Race and Development Engineer in the team to prepare

for the team’s final round in the BRCC championship at Zolder circuit on the weekend of

19/10/2014 where the team needs a win to seal the driver’s championship (CUP and GT3

categories). Spent 1 month before the race preparing the cars and drivers through previous

race data and trainings, at the race weekend was in charge of running the Cup car fighting

for the championship and developing their setups and guide the drivers on improvements

and made all strategy and setup decisions with the management team. The car Finished 1st

1 lap ahead of the competition and claimed the race win and championship, due to my

decision developing the setup and the car was 2 seconds faster in qualifying trim than it

was starting the season at the same track in the same conditions, the car was also 1 second

faster than it was in race trim. The Team owner and Team manager were very impressed

by my work and I was invited to continue working with the team for the remaining test and

(non-championship) race sessions of the season and beyond as the team’s race and data

Engineer. We won the final race of the season Race Promotion night.

II. Formula Renault 1.6 (10/2014)

I have also volunteered to work as an Engineer with Motorsport teams in various

competitions. I have had a lot of opportunities and have spent a race weekend (3/10/2014-

5/10/2014) working with Stuart Racing as a guest Engineer for the penultimate round of

the Formula Renault 1.6 season at Spa Francorchamps to assist the current team Engineers

in data analysis and setup for the young drivers. One of our drivers (car 17) was able to

qualify P2 and P1 for the races in a tough weekend with changeable conditions.

III. Formula Student (2010-2012)

This was the biggest project I have worked on to date, with a team of nearly 30 members

and a budget in excess of 250,000 EGP.I founded Cairo University’s Racing Team in 2010

with the aim to enter the prestigious Formula Student UK 2012 competition.

In the period from 2010-2011 I was the suspension team head, then I was promoted to

Technical director. My undergraduate graduation project thesis was also part of my work on

Formula student and was titled “Dynamic Modeling, Simulation and Development of a

Formula Student Vehicle”

I was appointed technical director of the project and part of the 3 man management board

where we secured in excess of 250,000 EGP funding for our project. Aside from managing

the 25 members available in the technical teams my tasks during the project work focused

on integrating a vehicle concept and make sure each subsystem performs as required for

the greater benefit of having the most complete package, this involved me taking lead roles

in working in the fields of Vehicle dynamics, Lap time simulations, tyre modelling and

analysis as well as being as involved as possible in the fields of power-train, brakes,

electronics, chassis and Aerodynamics/CFD which prepared me in working in such a

professional and real-time environment. That of course and the actual building of the

vehicle from scratch using manufacturing and Assembly techniques. By the end of 2012 we

were known as the best Regional team in the Middle East having proven ourselves at the

competition and earned international respect.

IV. Offroad car (2013-2014) Upon graduation I have also, with 2 other colleagues, started to work on making an

Egyptian offroad car with adjustable suspension using modern designs, simulation and

manufacturing techniques where we can put our knowledge to practical use to achieve a

tangible product that will be of great use to our community, The project was stopped

after the design phase because of financial problems.

My work on the vehicle was focused on Suspension design, vehicle dynamics and

Telemetry system. As a small 3-man team every one of us got the chance to work on

nearly every aspect of the car.

V. Robocon

In 2009, Cairo University made its first attempt to enter the international Robocon

competition. I was then in my second year of my Bsc. Mechanical Design Engineering

studies and entered the team later on in the year at a point when the team was behind

schedule and needed much help in the mechanical department to get ready for the

competition. The task was to make 3 Robots to carry out certain tasks in the competition’s

frame (including two robots carrying the third). Two of these robots had to be automated

while the third was controlled manually. My tasks revolved mainly on the design and build

of the robots and assisting the electronics team to implement the systems to control the

robots. The team was made up of 6 members, split equally between the mechanical and

electronic departments.

Upon joining I was handed all the design duties as at that point only system selection was

done, and the design process was not yet started where my skills would be needed. After

the design phase I assisted in the manufacturing, assembly and operation phases.

VI. PLC models During my studies I have undertaken 2 PLC courses, one as an undergraduate and one as a

postgraduate where I learned to model and control systems that can be found in a variety

of applications like Hydraulic Circuits, punch press, and some more detailed application like

ABS and Cooling systems in the automotive sectors.

VII. Finite Element Analysis I have done extensive work, as can be seen above, in the field of FEA. I have used several

software packages for different applications such as Cosmos, Solidworks Simulation, Star

CCM (Fluid analysis). I have also undertaken a specific Finite Elements analysis course as

an undergraduate student with a project final (seen below) which I chose to be optimizing

an upright design for minimum weight and maximum stiffness

VIII. Group Design Project, Lifter Crane (September 2010- January

2011) As a subject in our undergraduate course, we were instructed to work for a semester in 4

man teams to solve a problem currently facing a local press factory in transporting its die

presses from one location to the other. We were 4 teams each competing in providing the

most efficient and cost effective solution to the problem

I was assigned as the leader of Group B and our work was focused on designing and

analyzing a lift crane solution to the problem at hand. The team scored reputably and was

chosen as the joint best design to be implemented.

IX. HVAC design Internship at Dar Al-Handasah

Summer 2010 I did a one month placement at Dar Al Handasah design firm where

my work was mainly in understanding and designing HVAC systems. Internship

project was to design an HVAC system for a 3 floor office building and selecting the

mechanical components to be implemented.
