I am very pleased to do so. It has been a pleasure to be Ovidiu's Product Development team manager since 2012, as he joined our company, ROMBAT SA Bistrita, Romania. I am happy to write this letter of recommendation for Mr. BALAJ. In this letter I would like to express my respect and appreciation for this bright young person, who brought outstanding contribution to the work of our group. I was Ovidiu’s Product Development team manager from September 2012 to December 2015. Mr. BALAJ worked for our team on various projects as for Advanced Lead Acid Batteries development for different OEM’s, especially involved in concept, research and development phases, and based on his work, I would rank him as one of the best young electrical engineer we have ever had. Since the beginning of our collaboration I know him as hard worker person, with a very good understanding of the job’s challenges. Ovidiu distinguished himself by very good professional knowledges in the field of Electrotechnical Engineering, supported also by his excellent skills in digital communication (web design, MS office, especially robust Excel data management, 3D modelling by SolidWorks). His greatest talent is lies in strong customer-oriented work, related to their requirements and risks assessment, according to international standards. He is a creative problem-solver. He has a broad range of skills, as project development management for new battery types and good English language communication ability. He communicates his ideas clearly. He handles responsibility well. He grasps new concepts quickly and accepts constructive criticism and instruction concerning his work. His extraordinary ability to manage large amount of experimental test data was invaluable. He always takes an active role in humanitarian and social actions, by supporting any vulnerable colleague or persons in need. He finishes his work on schedule. When he has a concern or question about an assignment, he speaks his mind clearly and directly, giving voice to what others may feel but cannot or will not say. His main responsibilities were to elaborate reply to Request for Quotation of world leader car OEM’s. His weekly tasks involved to support the prototypes building and analyze the progress of batteries tests results. In my opinion, Mr. BALAJ is a hard-working self-starter who invariably understands exactly what a project is all about. Ovidiu consistently produces high quality work in a timely fashion. I give him my highest recommendation, without reservation. Please
