I Build Hardware That Works
Hardware & IoT Engineer | Custom PCBs | ESP32 Systems | Production-Ready Devices
I design custom PCBs and build production-ready IoT hardware. From PoE devices to secure telemetry and fleet management, I ship reliable systems for real-world deployment. Currently building AstraRMM, a hardware monitoring platform for MSPs.
About Me
I'm a hardware and IoT engineer focused on shipping production-ready devices. I design custom PCBs, integrate sensors, and deliver reliable monitoring hardware for real-world deployments.
I work with ESP32 microcontrollers (S3, C3), Ethernet/PoE systems, and sensors including CO₂, temperature/humidity, mmWave presence, and air quality. My projects span PoE air sensors, mesh presence networks, and network monitoring appliances built for continuous operation.
I prototype enclosures with 3D printing, design PCBs in KiCad, and own the full stack: schematics, power design, firmware, and network integration. I prioritize reliability, test plans, and maintainability so devices can be deployed and supported at scale.
Currently, I'm building AstraRMM, a hardware monitoring platform for MSPs with production-ready devices and pilot deployments.
What drives me: Shipping reliable hardware that teams can deploy with confidence.
