Hello, I have been associated with Hardware design (Circuit / Electronics design), PCB design, Library creation and Library database maintenance, PCB Manufacturing, Component procurement, PCB Assembling, Firmware and Functional testing for over 9 years. I have used various CAD/EDA tools for PCB design. Would you prefer any specific EDA tool for PCB design (or) any tool is okay? I will provide the PCB Manufacturing, Component procurement, PCB Assembling & Functional testing services too. I would like to take this up and are fully equipped to deliver the required files. 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. I look forward to hearing from you! Wish you a nice day! Thanks & Regards, Karthik

Thank you for reading this proposal . I'am an Electronics Engineer with professional experience of designing embedded systems with the process starting from circuit schematic design , MCU Algorithm development , finally leading to simulation and PCB designing . Following are the major projects that I have worked on: PIC18f452 based Data Acquisition Card for Three Phase AC Generators : Read real time generator parameters and display them on to the LCD and send it over the RF network using GSM SIM Comm Modem. (See portfolio). PIC18f458 based Electronic Load Controller for Micro Hydel Power Plant : Uses PI algorithm to ensure that the generated electrical frequency of the plant is steady. (See portfolio). Recently , I did a project that involved the design of PIC18 MCU based Assembly Line Controller for DC armature manufacturing . It had code , schematic , and a formal report Also , I have good experience in implementing transient and steady response modifiers , PD , PI , PID controllers . Also Phase lock loop is an important feature of controlling motors theses days . It can also come in handy Further my portfolio will reflect a perfect feedback score which shows a 100% client satisfaction . Let me know if you have any queries . Have a great day
