JST Systems
I build practical web systems for real workflows — and I’m taking on free portfolio builds to prove it.
Taking on 2 portfolio builds this quarter — software for a case study & feedback.

Open sign in →JST Systems is how I show up online — a solo builder focused on clear software for messy real-world jobs. I’ve worked in telecoms, medical, production, manufacturing, calibration and quality, so I’ve lived with awkward systems as a user, not just as a developer. I’m shipping working demos, learning in public, and looking for partners who want something useful built properly.
Portfolio weight beats empty claims. If you’ve got a real process that needs a web tool — simple or complex — I may build it for free (or near-free) in exchange for a case study, feedback, and permission to show the result. Solo operators, small teams, larger companies — all welcome if the problem’s real. You get software. I get proof. Everybody wins. Taking on 2 portfolio builds this quarter.
When a system has grown past the job, I like rebuilding from line one — lean, aimed at the workflow in front of you.
Design for how teams actually work — not a generic “industry standard” template — while keeping room for the paperwork that matters: ISO, CFR-style controls, calibration and quality trails where you need them.
Book-in, scanning, jobs, handoffs, roles — software that matches how people actually work.
Fast, hostable systems without a bloated stack. Easy to run, easy to own.
Landing pages and content systems for the public face of your work (in progress).
Plain language, sharp scope, demos you can click. No jargon fog.

Custody & calibration ops — book-in, lab windows, courier handoffs, scanning, roles. Click around the demo; if you want it for real, we can licence or host it. Free portfolio builds are a separate offer.
