About

Embedded engineer with 5+ years of experience taking IoT products from proof of concept to production — firmware, cloud connectivity, data pipelines and visualisation.

I write firmware for ESP32, STM32 and AVR microcontrollers, connect it to AWS IoT Core, and build the infrastructure around it with Lambda, DynamoDB, MQTT and Grafana. I also build Linux tooling in Python, Bash and Docker, and work on the hardware side — schematics, component selection and soldering.

Outside of client work I'm the main maintainer of Lilka, an open-source ESP32-S3 console, where I work on its operating system, SDK and tooling. I also build OpenTools — free calculators for embedded engineers.

Projects

• Lilka

  Main maintainer of Lilka — an open-source ESP32-S3 handheld console built to teach embedded development. I work on KeiraOS, its FreeRTOS/C++ operating system, and wrote the app catalog and the browser-based flasher.

  GitHub

• OpenTools

  Forty free browser-based calculators for embedded and electronics engineers — UART/SPI/I2C and CAN bit timing, STM32 timers, CRC, IEEE-754, PCB trace width and more.

  opentools.science

• Radar Plugin

  Grafana panel plugin for visualising data from various radar types, rendering sweep data in real time.

  GitHub

• WebSocket ⇄ Serial Converter

  Bridges a serial port to WebSocket so device traffic can be piped straight into a Grafana WebSocket data source. Ships as a Linux service.

  GitHub

• pocketTerm35

  Keyboard firmware on the Pico SDK and TinyUSB — one composite USB device exposing a keyboard with an FN layer and a gamepad that doubles as a mouse.

  GitHub

• embedded-umami

  Umami analytics client in C for ESP-IDF, Arduino and Linux — pageviews, custom events and identify calls, with the platform detected at compile time.

  GitHub

• LIFTS

  Independent elevator quality assessment system — collects sensor metrics, stores, processes and visualises them.

• Raz Odin

  Agricultural ground drone — embedded control systems and telemetry. Shown at the Scientific Picnics festival in Ternopil.
