Need something built?

I take on freelance work where my bench and my day job have already made me useful. Small scope, honest quotes, documented hand-off — the same standard as everything else on this site.

01 — Hardware

PCB design, layout, and DFM review

Schematic through layout, or a second pair of eyes on a board before it goes to fab. The DFM review is the one I would take first if I were you — it is cheap and it catches the expensive things.

02 — Firmware

Embedded — ESP32, PIC32, FreeRTOS, Zephyr

Bring-up, drivers, and task architecture for boards that have to stay responsive and stay asleep. Deterministic behaviour is the point, not a bonus.

03 — Web

Websites like this one

Custom‑designed, no template underneath. If your product is a physical object, I can put the real CAD on the page and let people turn it.

How it goes

Tell me what you are building and what is in your way. If I am the right person you get a scope and a number before any work starts; if I am not, I will say so and point you somewhere better. Everything I hand over comes documented well enough that the next person does not need me.

A paragraph about the project is plenty to start. Attachments welcome — schematics, photographs, a napkin sketch.
