PCB and CAD design, 3D printing and scanning, prototyping, software, server deployment and LLM training — taken from concept to shipped product by one engineer. In days, not months.
Every stage of product development handled end-to-end by a single engineer — no hand-offs, no agencies, no waiting.
Circuit design and PCB layout for connected products — from schematic to fab-ready board.
Production-ready mechanical design backed by deep technical and manufacturing knowledge.
One-off bespoke items, early-stage prototypes and small-scale production runs — printed, finished and functional.
Physical parts captured into precise digital models — for replication, repair or redesign.
The code that brings hardware to life — firmware, web and everything between.
Server-side deployment done properly — virtualised, containerised and maintained.
Dataset collection and model training for applied AI — built into real products, not demos.

J. O'Connell — United Kingdom
Most products die between departments — the mechanical team waits on electronics, electronics waits on software, software waits on infrastructure. I remove the queue entirely: one engineer who designs the board, models the enclosure, prints the prototype, writes the code, deploys the servers and trains the models.
That's why I can turn products around in days where others quote months.
Brief me on the product, the deadline and the budget — I'll come back with what's possible and how fast.
