Custom software & automation,
built end-to-end.

I design and build the tools businesses actually use — dashboards, data pipelines, scrapers and automation that turn scattered data into decisions. From first idea to a running system.

How It Works

no agencies, no hand-offs

01
Scope

A short call to understand the problem. You get a clear, fixed-scope proposal — what gets built, what it costs, when it ships.

02
Build

I build in short cycles with something clickable early. You see progress weekly, not a big reveal at the end.

03
Ship & run

Deployed on your infrastructure or mine, with monitoring and docs. Systems that keep running — not prototypes that rot.
