Built in South Florida

Made by hand

Closing the gap between big tech and small business.

I'm Dharyl, a one-person software workshop in South Florida. I take the operational problems small companies live with every day and turn them into apps, AI agents, and quiet little tools that get out of the way.

Apps I make for myself, and for you.

Alongside client work, I build and ship my own apps for iPhone, iPhone Duo and Android. Small, calm and carefully made, with no ads and no tracking.

Bill audits, carrier negotiation, and right-sizing for small companies that don't have a telecom person, and shouldn't have to become one.

A patient, in-person tech person, especially for seniors.

Home and small-office troubleshooting, new device setup, Wi-Fi and printer fixes, password and account cleanup, scam-call hardening. Plain English, no condescension.
