Heorhii Romanenko — Software development · Embedded · Automation

Website E-Mail Instagram Figma

I automate whatever repeats — build and flashing workflows, release pipelines, smart-home devices. Native where possible, minimal everywhere: Swift for Apple platforms, C/C++ for microcontrollers, plain HTML/CSS/JS for the web.

Showcase

Concordia

C++ Zephyr Matter Thread

Matter-over-Thread bridge built only from microcontrollers: an ESP32-C6 with a web panel pulls data from any HTTP API, an nRF54L15 exposes it as Matter devices for Apple Home, Google Home and Alexa.

ServerMaster

Swift SwiftUI macOS CLI

Local web server manager for macOS and Windows: static sites, PHP with a database, Node.js apps and custom commands — started, stopped and monitored from one window. Plus a Swift CLI.

Micro Matter Switch

C++ ESP32-C6 Matter

Compact Matter switch based on the XIAO ESP32-C6 with its own 3D-printed case.

Safari AI Extension

JavaScript Safari iOS

Safari extension generated with Apple Intelligence and then edited by hand. A guide for developers on macOS, iOS and iPadOS 27.
