Forth Developer: Firmware and Bootloaders on Stack-Based Language

I am a Forth developer and write compact stack-based code for embedded firmware, bootloaders, and places where heavy toolchains simply do not fit. My code lives on microcontrollers with a couple of kilobytes of RAM, at the earliest stage of board bring-up when nothing else works yet, and on devices that must remain interactive without a debug cable perpetually hanging at the bench. Instead of a bulky runtime, I give you a tiny kernel and a dictionary of words that map directly to your hardware, so the whole system stays small enough to read in an evening and predictable enough to trust in the field.

The key difference of Forth that I rely on every day is an interactive console right on the target device. I bring up a serial terminal, poke registers, define and redefine words live, and grow firmware from the bottom up from primitives that can be tested one by one. Board bring-up problems get cornered in minutes rather than reprogramming cycles, and the final image carries no bloat: no unused libraries, no speculative abstractions, only words the product actually calls. I comfortably write my own interpreters with threaded code, port existing Forth to a new die, or embed minimalist Forth in a large C project as a control scripting layer.

I care more about size, determinism, and clarity than clever tricks, and I document the dictionary so your team can develop it after handoff. If you have a stubborn board, a bootloader that must fit in a flash corner, or a control task asking for a tiny interactive language, I will help.
