I'm an embedded systems engineer, currently building production systems at Richard Pieris & Company — robots, edge IoT infrastructure, battery management systems, and real-time video streaming platforms. Before this, I spent several years in Russia working across embedded electronics, fire safety systems, HVAC firmware, and nanofabrication research.

My background is a bit unusual. I started in nanotechnologies, moved through semiconductor physics and solar cell research, and ended up deep in firmware and hardware-software co-design. That path gives me a way of thinking about problems — from the electron level up to the cloud — that I find genuinely useful.

I care about the full picture: schematic to PCB to firmware to backend to deployment. And I document the process, not just the outcome.

WebRTC Telepresence Robot Control Platform — A production bidirectional video and audio streaming system deployed across a robot fleet. Hardware-accelerated H.264 encoding via V4L2, achieving under 100ms latency on Raspberry Pi 5, with serial motor control, PTZ camera control, and multiple WebSocket endpoints.

Production MQTT Edge Client — A resilient edge computing client with offline queuing over SQLite, exponential backoff, QoS 0/1/2 support, dual storage architecture, and 24-hour soak tested. Built to survive real network failures, not just ideal conditions.

6-Layer UPS Board for Raspberry Pi 5 — A custom 6-layer PCB with intelligent power management, BQ25750 synchronous buck-boost charger for 6S Li-ion/LiPo, dual-source input switching, thermal monitoring, and graceful pre-depletion shutdown. Manufactured via JLCPCB.

Battery Management System — Full-stack BMS with C/C++ firmware, real-time web monitoring, live telemetry graphs, multi-channel voltage/current monitoring via I2C ADC, and cloud backup to PostgreSQL.

Always building. Always curious.
