I'm an embedded systems engineer transforming the energy landscape—device by device.
With deep expertise in Modbus communication (TCP/RTU) and Node.js, I create IoT solutions that connect B2C and C&I customers to the grid—securely, intelligently, and in real time.
Mission: Make every consumer, prosumer, and business part of a decentralized, resilient energy ecosystem.
I build systems that:
- Speak fluent Modbus TCP/RTU, seamlessly implemented in Node.js
- Enable both households and businesses to join energy markets
- Integrate partial customers into Virtual Power Plants (VPPs)
- Deliver real-time device response for FCR, aFRR & imbalance markets
- Power peer-to-peer local energy trading
-
