I’m a Real-Time Systems Engineer with 5+ years shipping production-grade systems where hardware meets software. I build safety-critical platforms across medical simulation, industrial mining, and connected IoT—processing high-frequency sensor data (200Hz) with sub-100ms responsiveness.

In my current role at MedtrainAI Technologies, I architected a production medical simulation platform for 200Hz live sensor streams, synchronizing ECG, SpO2, and EtCO2 waveforms with waveform rendering and SVG manikin animations. I also built a Flutter mobile app with full BLE/ESP32 integration, including real-time audio alerts and AI-driven performance feedback, plus complete session replay from recorded JSONL event logs.

Previously at Durbin Technologies, I engineered a safety-critical real-time mining IoT dashboard using WebSocket and MQTT, streaming fire suppression events, GPS positions, nitrogen discharge states, and drowsiness alerts across multiple mining companies. I also served as a founding engineer for a B2B fleet-management SaaS, designing architecture, database schemas, and APIs with measurable impact through predictive maintenance alerts and remote asset visibility.

I’m especially energized by end-to-end delivery—from firmware and mobile to React dashboards, Node.js APIs, PostgreSQL design, and AWS deployment—and I independently build and sell software products. I’m targeting senior remote engineering roles in healthtech, industrial IoT, and real-time data systems where reliability and latency matter.
