01 / What I do
What I do
From prototype to deployment on hard embedded problems.
Firmware Architecture
Bare-metal & RTOS firmware for STM32, ESP32 and RISC-V — from bring-up and drivers to field-reliable production code.
Protocol Design
RS-485 multi-node, Modbus RTU/TCP, DLMS/COSEM, CAN and MQTT — robust communication for constrained, field-deployed systems.
Secure Hardware
ATECC608A secure elements, ECDSA signing, air-gapped key management and anti-tamper design for trusted devices.
Smart Energy & AMI
IEC-compliant DLMS/COSEM metering, STS/CTS prepaid, and DCU/HES/MDM integration for utility-scale deployments.

About
I build embedded systems that have to work outside the lab: secure hardware wallets, STM32-based control systems, military robotics subsystems, and advanced metering infrastructure. My work covers firmware architecture, protocol design, system integration, debugging, and technical leadership. For clients, that means reliable delivery on hard embedded problems. For professors and research collaborators, it means applied work grounded in implementation, experiments, and publishable results.

Research Statement
My goal in graduate study is to advance secure, deterministic communication for resource-constrained embedded systems — the layer where cryptography, real-time communication protocols, and field hardware meet. In industry I have shipped RS-485 multi-node control for military EOD robotics platform, DLMS/COSEM advanced metering for national utilities, and air-gapped hardware-wallet signing on secure elements (ATECC608A). These deployments surfaced open questions I want to study formally: how to guarantee tamper-evident, real-time messaging across multi-node field networks under adversarial conditions, and how to make hardware-rooted cryptography practical on low-power MCUs. My aim is to turn these applied problems into reproducible, journal-level research.
