About

I am an electronic system integrator and engineer with strong experience in designing and building embedded hardware, GSM/GPS devices, automation systems, and RF/electronic equipment. My background includes end-to-end product design covering PCB layout, hardware and firmware development, project planning, supplier FAT and QA activities, and quality control for onshore processing units in large gas-field projects.

I support clients with product design and OEM/ODM development, including concept refinement, circuit and PCB design, prototyping, and functional testing for embedded and IoT devices such as GSM/GPS trackers, automation modules, and control boards. I also provide product research and technical feasibility assessments, evaluating system architectures, components, and suppliers for solutions including GPS/GSM trackers, RFID systems, automation platforms, and sensor interfaces. In addition, I assist with supplier FAT and QA support by reviewing drawings and material certificates, witnessing FAT, and verifying compliance of electro-mechanical and electronic systems with technical specifications.

My technical skill set includes the use of tools and technologies such as Altium, PCB design, AVR microcontrollers, GSM, GPS, RFID (UHF, HF, and active RFID), automation systems, prototyping, and reverse engineering. I also bring strong QA and inspection capabilities, including familiarity with weld testing methods (PT, VT, MT, UT), condition monitoring techniques such as vibration, thermal, current, and oil analysis, electrical inspections to code, FAT execution, and supplier management support.

My ideal clients are startups and businesses seeking a technical partner to design and prototype custom electronic or IoT products, as well as buyers who need an experienced engineer to translate functional ideas into detailed hardware specifications and provide supplier FAT and QA support.
