I am a multidisciplinary engineer and applied mathematician with over 12 years of experience in the design, development, and integration of advanced electronic systems, embedded firmware, and control algorithms for aerospace, robotics, and autonomous navigation applications. I have a deep expertise in PCB design, real-time firmware development, and mathematical modeling of dynamic systems, particularly in navigation, guidance, and control (NGC). And also I have rich experience in Internet of Things and developed RF/Wireless products used in medical health-care systems for over 5 years. I have a proven track record of delivering high-reliability systems for both field-deployed robotics and aerospace platforms. From systematic design & algorithm development to detailed implementation into hardware & embedded systems, I have a rich experience in multiple projects including robotics ( UAV & UGV & mobile robots development), IoT and mathematical algorithm development & implementation. ?
