Work Certificate

Hi I need an objective eye on the following work certificate can someone lend a hand of assistance?
Thanks in advance

To whom it may concern
This is to certify that Mr. XXX was employed by ABC from October ‘XX till November ’XX in the
industrial unit of the company, in the industrial zone of XYZ. This time period was crucial
for the development of the company because it was undertaking a x.x million euro expansion
investment. The plant produces a variety of plastic waste bins and other plastic products
though injection molding using high density polyethylene. XYZ has evolved to one of the most
important European construction companies with x.x million euro turnover for XXXX.
Cooperation with Mr. XXX was in the following sectors:
1. In the design and implementation of the quality assurance system according to the
standards set by the Certification Division for the organization/ arrangement of the “ISO
9001 Quality Assurance System”. It is important to mention here that the crucial initial
stages of the project were completed successfully with his personal contribution.
2. In the computerization of the secretarial support functions of the industrial facility
making use of modern technology (Microsoft Server Family & Office, Local Area Networks, Web
technologies) and the training of the administrative staff in the installed software and
according to the needs of the plant.
Regarding Mr. XXX I have to remark the following:
He has worked with relentless zeal in the execution of his tasks and is distinctively endowed
with commitment, patience, insistence and eagerness. He is courteous, honest and
straightforward, in addition to being very discreet. Except for these, he possesses strength
of will, self-control and composure, which he has displayed many times and under various
circumstances. He has shown significant administrative and organizational skills in the
execution of his duties. He possesses excellent skills regarding the development of computer
systems taking into account the needs of the plant. In the use of information processing
software (statistical analysis, data analysis, spreadsheets etc.) he displayed speed and
effectiveness ensuring their framing in graphics of a notable artistic flavor. He has shown
great skill in handling –in both linguistic and diplomatic terms- the Company’s European
partners who visited our Komotini industrial unit during our collaboration. He takes
initiative when he is asked to and does not hesitate to express his view when he considers it
necessary, always decently and in the line of our collaboration. He accepts in a constructive
spirit any critique for possible shortcomings or mistakes on the part of the Company, for
which he does not feel offended but, on the contrary, he takes advantage of, as an enhancing
element of collaboration.
Due to his skills and commitment, I wish him success in his ambitions
Honorably
XXX
Director in Chief
