I am a multi-disciplinary Automation Engineer holding a Bachelor of Engineering Technology in Instrumentation and Automation (Hons). I specialize in bridging the gap between physical hardware design and digital control systems. With industrial experience acting as an Automation Engineer at Hemas Consumer Brands, I bring real-world manufacturing and automation principles to every freelance project. I offer full-stack prototyping: from 3D mechanical modeling in SolidWorks and PCB design, to writing industrial PLC logic and developing custom, globally accessible web dashboards (React.js, Python) to control IoT hardware. I utilize high-performance, dedicated RTX hardware to ensure rapid turnaround times for complex physics simulations and photorealistic 3D renderings. Whether you need a product designed for manufacturing or a complete hardware-to-software ecosystem, I deliver robust, production-ready solutions.
