Hi, My name is Stefan Ponova, and I work at a company as a power electronics application engineer. I have experience in working with SMPS and I can provide you good designs. I appreciate communication when working as a freelancer, and I want to assure you that I will respond to your questions / ask questions regarding the project any time when it's necessary, because I believe that good communication leads to positive results for both sides. I am not an arrogant person, and I won't bid with a large amount of money, I want to prove myself to an employer first, and then if he appreciates my work, continue in future collaborations. So, If you'll give me a chance to take part to your work, I will respond in the same manner, handling you good quality projects, as soon as possible. Please let me know if you want to have a more detailed discussion. I look forward to hearing from you! Wish you a nice day!
