The Multidisciplinary Engine

"Innovative Engineer specializing in AI Integration and Industrial Automation. Proven track record in transitioning manual operations into automated, AI-powered ecosystems using the Power Platform and Azure, managing the full project lifecycle from server deployment to front-end delivery."

Hello! I am Gimhana Jayasekara. I hold a Diploma in Electronics & Telecommunications Engineering and am an **Associate Member of the Institution of Incorporated Engineers, Sri Lanka (AMIIESL)**.

With a career spanning electronics (Arduino/ESP32, Modbus/MQTT) and digital process transformation, I have spent the last 4 years delivering scalable solutions within the manufacturing sector. I offer a rare combination of industrial hardware expertise (SolidWorks, PLC, PCB Development) and modern software proficiency (Node.js, Firebase, SQL).

I am interested in self-learning multiple tech domains including Electronics, Industrial Automation, Digitalization, System and Process Automation, Web development, programming, and Graphic Designing. Also improving my leadership and project management capabilities to provide leadership for high performing teams to deliver high performing products and solutions.

Beyond technical execution, I lead autonomation and business transformation projects from Ideation to Closure. I apply structured project management frameworks, budget controlling, and team leadership to manage the full project lifecycle, ensuring automation systems deliver tangible work reduction and business value.
