Security agents was trying inflitrating and intimedating me while I was working for Ethiopian Airlines as a computer programmer while working on a project on the General accountisng system software. While I was working for the general accounting sysytem software after we have spent a year of our effort . I showed up my deligence in the Airline by performing an extra effort . The Chief information was attracted to me when I developed a fuel cost optimization software which took all the airline flight inforamation 
into consideration such as payload, altitude , flight, plan amount of fuel that the aircraft can upload and fuel cost on each of the destinations. I got the detail flight plan information of a specific route. and developed an optization software which dictates each pilot how much fuel each of the aircraft should have to tanker in each of the destination so that the overwhole round trip of a specific flight might end with the minimum fuel cost. This dynamic optimization software has supposedely saved the airline more than 2 million USD per annum than they used to use customerly without detailed pre planning. 

The whole concept of the optimization software is to allow a pilot to fully tanker more fuel on destination which have the minimum cost of fuel. But as the plane is fully tankered there are three major drawbacks. First the airplane can't uplift so much passengers or payload , which is the main revenue of the airline. The second problem is that the airplane will burn extra fuel because it carried extra payload which is the fuel. The third problem was the aircraft cannot maintain the optimum flight altitude which is suitable for optimum fuel conservation . The fourth problem which is straight forward is the aircraft will be unable to takeoff and lift up to the optimum level of altitude of flight which is airodynamically suitable for optimum fuel burn.

I was working this project for my paper for an Optimization Research caurce which I was taking under a supervision of my Professor named Harege-Work. He had a strong tie with a chief information officer of the Ethiopian Airlines, Mesfin Tassew. While I was touring all the departments of the Ethiopian Airlines by the help of Ato Mesfi Tassew, After I was travelling through the finance department I came accross that the Airline. I came accross their big expense was the fuel cost like 40 million USD per annum. So while I went to the department of tankering after I got fuel cost of every destination , I was enlightened realized that this specific part of the Airline drawback can be relieved by the tool which I got in the operation research course. I used linear programming tool inorder to develop and formulate and define the problem and reach to an optimization solution which helped the airline company especially Ato Mesfin Tassew the chief information system officer which was in charge of all the Information Technology System of the Airline . I proposed what problem I identified in the fuel tankering system and he was very glad that his office was preparing and was in an analysis stage to buy an off the shelf system to incorporate with the new flight plan system which the bought a year ago. He was also an Electrical Engineer who made his  Masters in Communication Engineering and also in MBA. He was very much interested and supportive. He began to make me solve practical flights than spend my time only on mathematical speculations and make me labour even more than for a school paper. I woked with him and toiled to my bones to make this project real. So I succeeded and make it practical and incorporate it with the existing flight planner of the Airline. Had this 2 million USD been saved by an employer the campany policy declares that any saving by an employee will . Any employee who made a saving for the Airline he would have rewaded 5% of the saving. He asked me and pushed the project to the upper officials so that I might be compensated for whatever saving I made to the company. But since I was not working in the airline the policy makers refused to let me benefit out of the employee savings reward. But He was unhappy with them and wanted to offer me a full time job and at the same time to pursue my post graduate studies and also he offered me a trainning. So I accepted the offer and started working for the airline    . When I joined the airline the Airline has lost 30 million birr in debt . After a year I joined the Airline, the Airline has earned a profit of 40 million Ethiopian birr. The CEO even mention Fuel tankering as the reason for the profitability of the company. More than the reward or 5% money . The confidence and moral to be a souce of such a tremendous profit to a big organization such as Ethiopian Airlines made me feel proud and have confidence in myself and gave me a mining in life and great success.

Soon after I was hired I became the key player to on going general accounting software system development . They were lagging behind to proceed the project as they were not sure what kind of Database management system should they have to use. Since I had a solid prior knowledge of Oracle , I recommended it to the Chief Information officer due to its scalability security and perforance and reliability of Oracle database Management System . Since He had a confidence in me he accepted my proposal and even wanted me to work in the project as a lead with the one who developed the system analysis of the accounting system. I was given responsibility to stir the programmers working and to supervise the software development.

But soon the programmers who were assigned before were not happy about my placement. They were not happy my affiliation with the CIO , because he was very much interested of my deligence and performance. They even hated me because he let me go to school even during the office hours as a full time student for my post graduate studies. And they were made even bitter when the CIO let me learn three Oracle database trainning courses while they were only sent to only the developers trainning course. This advantage and benefit which I gained through my hard work and deligence exposed me to a big time hatred. So they were trying to jepordize which so ever way they got advantage and opportunity  They were always trying 

But rivals who hated my
