Built for the small tasks that slow down bigger work.

Hi, I'm Grzegorz. I'm an embedded engineer focused on firmware, connected devices, and practical developer tooling. devtoolsforme is where I publish the utilities I keep reaching for while building and debugging real systems.

devtoolsforme is a browser-first collection of practical developer utilities. The goal is simple: help you move faster without needing a heavyweight app, browser extension, or backend service for every tiny task.

Most tools here run entirely on your device. That keeps the site fast, private by default, and inexpensive to maintain while still being genuinely useful day to day.

The product is shaped around everyday workflows: formatting JSON, inspecting tokens, working with URLs, comparing text, checking accessibility colors, and converting data into forms that are easier to use.

Alongside the tools, I also help teams with embedded firmware work, IoT architecture, and internal engineering workflows that benefit from lightweight, purpose-built utilities.
