Selected work

-
GESTKOR database
A full redesign of the corporate database behind a retail maintenance management system, from data flow diagrams through to production deployment.
-
GeroHub
An automation suite for small businesses. Its first app pulls six messaging channels into one inbox and uses AI to decide who to answer first.
Users bring their own AI key and their conversations stay encrypted under their control — a decision that complicates sign-up and removes the objection that kills the sale.
-
Ishikawa Creator
A cause-and-effect diagram without drawing one. The same information in a nested structure you fill in minutes and save as JSON.
-
Mallas Trujillo
A quoting system for a safety-netting company. Prices and discount tiers are edited inside the app, not in the code.
-
Mi Malla
A quoting tool with a reusable client record: find the client, load their details, then capture the areas to be installed.
-
Plenty Tap
Budgets by number of uses rather than by amount spent. Mark a use from the phone or the watch; both stay in sync.
-
Display Preset
Saves complete monitor configurations — resolution, refresh rate, order and position — and switches between them from the system tray.
-
Gaspary Digital
The static site behind my freelance practice, written so that both Google and generative engines can read and cite it.
