Projects
Production embedded systems — from secure hardware wallets to military robotics.
STM32 Engine Control System (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, Modbus RTU/TCP communication, and CAN diagnostics.
Industrial Stepper Motor Controller Board
EBabutzky GmbH (Germany)
STM32F4-based precision motion-control board for EBabutzky GmbH (Germany) — stepper/H-bridge drive with closed-loop PID and encoder feedback, controllable over Modbus RTU/TCP. Evolved from a single-MCU design into a distributed dual-MCU architecture for safety and precision.
NEXTcampusAI — AI University Admissions Platform
Live product · nextcampusai.com
A live, in-use AI product I conceived, scoped, and shipped: NEXTcampusAI matches applicant profiles to German master's programs, flags eligibility gaps before they become rejections, and tracks a multi-university, multi-portal application pipeline in one place. Real users today — nextcampusai.com.
NextBusinessAI
AI-driven advisor for social media strategy, automation, and performance-based iteration — live product.
Air-Gapped Crypto Wallet — Hardware Security
XDC Network
Offline hardware wallet with secure-element-based key protection, built for XDC Network — private keys are generated, stored, and used for signing entirely inside an ATECC608A secure element and never leave the air-gapped device.
Smart Meter Firmware — DLMS/COSEM
Standards-compliant metrology and multi-channel communication firmware for utility-grade smart electricity meters, built on the Hitrend HT5023 metrology MCU.
Advanced Metering Infrastructure (AMI) Platform
System architecture for HES, MDM, STS-based prepayment, and multi-vendor meter interoperability — connecting utility-scale smart meters to billing and business systems.
ROV Control System — Explosive Ordnance Disposal (EOD)
Military-grade remotely operated vehicle for Explosive Ordnance Disposal — real-time multi-node robotics, motion control, and a standoff RF operator link. Delivered as field-ready units, deployed in UN operations, and the multi-node protocol was published at ICCIT 2024 (IEEE) — Best Paper & Best Technical Presentation.
Agritech Automation
IoT-based greenhouse and irrigation automation with environmental sensing, MQTT data pipelines, and remote monitoring dashboard.
Modbus RTU/TCP Protocol Stack on STM32
Full Modbus RTU and TCP protocol stack implementation for STM32 microcontrollers used in industrial communication, ROV multi-node bus, smart metering, and engine control integration.
RISC-V Thermal Printer Firmware (Grozzi Brand)
Mass-production firmware for globally distributed Grozzi-brand thermal printers using JL Technology RISC-V SoCs. USB, Bluetooth, BLE, and Wi-Fi connectivity with ESC/POS and CPCL protocol support. Developed in a CKD manufacturing environment at THT-Space Electrical, Nilphamari EPZ.
