Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. I have good knowledge base and experience in designing, building and debugging transistor amplifier circuits. As I understand from the project description you are looking for an electronics engineer capable of reviewing an already existing circuit design of a BJT amplifier. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Review of existing circuit 3. Review of project documentation 4. Feedback based on project documentation and existing circuit 5. Discussion over your project and circuit Furthermore, I could import your design into a circuit simulation environment in order to gain a better understanding of what is going on and where the potential problem might be. Delivery term could be further negotiated once I start working on the project. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for you time. Kind Regards Martin Botsov

I'm a senior in computer engineering and just had a class on analog electronics which focused heavily on amplifier circuits. I have the ability to simulate the tests and run physical tests in a lab. My project was using BJT's to create low, band, and high pass audio filter amplifiers so I'm quite savvy in the area. I look forward to hearing from you!
