I am a multidisciplinary engineer specializing in the integration of mechanical design, electronics, and software development to deliver complete, real-world engineering solutions. With a strong foundation across these domains, I bring a systems-level perspective that allows me to design, prototype, and implement projects from concept to deployment. On the mechanical side, I have extensive experience in CAD design, product development, and manufacturing-ready solutions. I focus on creating efficient, practical designs that consider real-world constraints such as materials, fabrication methods, and cost optimization. In electronics, I work with embedded systems, PCB design, and hardware integration. I am comfortable developing schematics, selecting components, and ensuring reliable communication between hardware and control systems. On the software side, I develop firmware and control logic for embedded devices, as well as higher-level applications for automation, data acquisition, and system monitoring. I have experience working with microcontrollers, PLCs, and industrial communication protocols, enabling seamless integration between hardware and software systems. What sets me apart is my ability to bridge these disciplines. Instead of treating mechanical, electrical, and software components separately, I design them as a unified system—resulting in more robust, efficient, and scalable solutions. I have worked on projects ranging from industrial automation and embedded systems to custom machinery and prototyping. I collaborate effectively with cross-functional teams, including mechanical engineers, electrical engineers, and software developers, ensuring smooth communication and successful project delivery. If you are looking for someone who can take ownership of a project end-to-end, reduce complexity, and deliver practical engineering solutions, I would be glad to help bring your ideas to life.

Worst Experience won't even rezpond once milestone is created wasted my entire month and not even started work infact I had to cancel project . Once project given don't expect results as this freelancer will only respond you with work is going on if you ask to send update he will reply can't send he is out or not well just keep shuffling reasons but won't ever show you progress as he don't even try to start work
