About
I am a Mechanical Engineer by training and an Automation Engineer by passion. Over the past seven years, I have solved complex industrial challenges—from bespoke machinery to multi-site automation rollouts—by uniting control hardware, software, and data.
Recognizing that the future of manufacturing is in data, I now focus on building the complete Industrial Internet of Things (IIoT) stack. I architect secure, scalable pipelines that capture shop-floor signals, contextualize them at the edge, and deliver trustworthy insights to decision makers in the cloud.
My multi-platform expertise lets me choose the right tool for every project. Whether you run Siemens, Allen- Bradley, Mitsubishi, CODESYS, or ABB systems, I deliver maintainable logic, structured documentation, and a smooth handover to your operations team.
My career began designing and programming custom machinery, grounding me in the physics, safety, and operations of industrial equipment.
Specialized in PLC logic, SCADA, and edge computing to connect plant-floor assets with business systems and decision makers.
100% Job Success Score on Upwork with remote collaboration experience across North America and Latin America.
