Senthilnathan T.

Electronics and Software Engineer with over 21 years of engineering experience across electronics, embedded systems, firmware, and software development. I help clients develop complete engineering solutions — from electronic circuit design, PCB design, and embedded firmware to device drivers, system integration, and desktop/mobile applications. My expertise includes: • Analog and digital circuit design • Power electronics and SMPS design • Embedded hardware design and PCB development • Bare-metal firmware and microcontroller development • USB, HID, smart card, and hardware/software integration • CPLD and programmable logic • C/C++, C#, Objective-C/Swift, Python, and JavaScript • Windows, macOS, Linux, and iOS development • Kernel and user-mode device drivers • macOS system extensions • .NET, Win32, Qt, REST APIs, networking, and system integration • Cross-platform application development I am comfortable working across the complete hardware-software stack — from analog and digital electronics and microcontroller firmware to low-level operating-system integration and end-user applications. I can contribute to new product development, existing product enhancement, hardware/software integration, troubleshooting, prototyping, and complex engineering problems that require expertise across multiple technical domains. I have been freelancing since 2009 and have achieved Top Rated Plus status on Upwork. If your project involves electronics, embedded systems, firmware, system-level software, or a combination of hardware and software, I can help take it from concept and design through implementation and testing.
