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.

Air-Gapped Multi-Chain Hardware Wallet
XDC Network
Secure hardware wallet for XDC Network supporting multiple wallets and multiple blockchain networks. Air-gapped offline QR-based signing workflow, ATECC608A secure element integration for ECDSA key management, and UR:CRYPTO-HDKEY encoding.
DLMS/COSEM Smart Meter & AMI
Advanced Metering Infrastructure (AMI) solution for Bangladesh utilities. Smart meter firmware with DLMS/COSEM, STS/CTS prepaid functionality, Data Concentrator Unit (DCU), Head-End System (HES), and Meter Data Management (MDM) integration on STM32.
Military EOD ROV — Bangladesh Army
Bangladesh Army
Military-grade Remotely Operated Vehicle for Explosive Ordnance Disposal (EOD). Custom RS-485 multi-node communication protocol, real-time multi-axis control, RTK GPS, LIDAR, robotic arm, and 1.4 GHz wireless video link. 4 units delivered — deployed in United Nations operations and Peru Army.
Dual-MCU Industrial Motor Controller Board (Modbus RTU/TCP)
Ebabutzkey GmbH
A dual-MCU industrial motor controller board that separates real-time motor control from industrial networking. A dedicated communication MCU runs the Modbus RTU/TCP stack while a second control MCU drives the motors; the two are bridged by a high-speed SPI link so network load never disturbs the control loop.
Engine Control Unit Development (ECU)
EBabutzky GmbH, Germany
Custom ignition and engine control unit for a German automotive engineering client (EBabutzky GmbH). Real-time multi-cylinder ignition scheduling with 60-2 crank encoder, dynamic dwell control, stepper motor control board, and CAN diagnostics.
