How we work
Discovery
We learn your business, your users, and your goals. No assumptions — just questions until we understand the problem inside out.
Design
Wireframes, prototypes, and architecture. You see everything before a single line of code is written and sign off on the direction.
Build
Custom code, real infrastructure, weekly demos. You're never in the dark — you see progress as it happens.
Launch
We deploy, monitor, and make sure everything runs smooth. Then we stick around for support and iteration.

What clients say
“Core Dev built us a custom site with a quote engine that calculates drive time, texts the customer a confirmation, and syncs everything to our calendar. Customers book online 24/7, reschedule, cancel — all from the client portal. Waking up to three people already booked is a great feeling. More time with my family. Bookings are up and my phone barely rings anymore — in the best way possible. I would put more stars if I could. Highly recommend.”
“Our firm was drowning in manual intake. We had a WordPress site, a separate CRM, and everything was held together with email threads. They rebuilt the whole thing — one system, client portal with passwordless login, automated document generation. Our paralegals got 10 hours a week back. It's not even close to what we had before.”
“We needed an AI agent that could actually book appointments, not just answer FAQ. Core Dev built a voice + chat system that handles after-hours calls, qualifies leads, checks provider availability in real time, and books directly into our EHR. It handles about 70% of inquiries without a human touching it. Patients love it.”
