What I do

Three areas, one engineer

Most teams split device integration, embedded control and backend work between different people. I've shipped all three, which means fewer hand-offs and fewer things lost between them.

01

Kiosks and embedded systems

Certified machine software on Raspberry Pi: custom I/O boards over RS232, e-ID and RFID readers, ticket printers, coin and bill acceptors, and recovery after power loss.

02

IoT and monitoring

Sensors in, decisions in the middle, relays out: a Raspberry Pi and Arduino system controlling a mining farm, and an ESP32 pH and ORP monitor with calibration.

03

Backends and fleet systems

A C++ fleet server that collects data from every machine over WebSocket and reports to a regulator, plus APIs, admin panels and the Linux servers they run on.

Multikiosk: software for a certified self-service kiosk

All the software for a government-certified self-service kiosk: device drivers, e-ID age checks, printers and payment devices, recovery after power loss, and the accounting that regulators audit.

Kiosk fleet server and regulatory reporting

One server that every Multikiosk in every bar reports to over WebSocket, using a protocol I designed. It builds the regulatory reports for the Belgian Gaming Commission, and the operator manages bars and machines through its admin panel.

Automated monitoring and power control for a mining farm

A Raspberry Pi that watches every mining rig, decides when one needs a reboot or a shutdown, and carries it out through Arduino-driven relays, with a web panel for remote control. I built the control system: the Pi, the Arduinos, the software and the networking.

Client project · open source · 2026

ESP32 wireless pH and ORP monitor

ESP32 firmware built for a client to measure pH and ORP: temperature-compensated readings, calibration with known liquids in the browser, a password-protected setup, and a live dashboard and JSON API over Wi-Fi.

Architecture

From device to regulator

One system I built end to end: inside each kiosk, device services and the main application share the work, and every kiosk reports over 4G to one fleet server, which sends the required reports to the regulator.

From device to regulatorInside each kiosk, buttons, the coin and bill acceptors and the door switches connect to the inputs of a custom I/O board, whose microcontroller keeps the counters in EEPROM and talks to the main BlitzMax application over RS232; and USB devices connect to C++ device services; the two talk over a local socket. The C++ services send status and counters over a 4G modem, using a WebSocket protocol, to a fleet server on a Raspberry Pi. Every kiosk and the operator's admin panel connect to the same server, which sends the required reports to the Belgian Gaming Commission.INSIDE EACH KIOSKMachine inputsbuttons · coin · bill · doorsUSB devicese-ID · RFID · ticket printerI/O boardMCU · counters in EEPROMDevice servicesC++ · multithreadedMain application · Raspberry Pi 4BlitzMax · serial I/O protocol · power-loss recoverysoftware checksum · bookkeeping and statistics4G / GPRS modemstatus and counters leave the venueUSBRS232local socketONE SERVER FOR THE WHOLE FLEETEvery kiosk (×N)same software, same protocolOperatorat the warehouse · browserWebSocketbars, machines,warehouseFleet server · Raspberry Pi · LinuxC++ WebSocket protocol service · C++ reporterCakePHP admin panelWebSocket · my protocol · over 4GBelgian Gaming Commissionregulatory reportsmy workclient’s hardware and firmwarethird-party
