Built CoolFlow HVAC in Lovable around one simple insight:

An empty calendar slot is not necessarily a feasible appointment.

CoolFlow is a 4-person residential HVAC company in Austin, where the owner currently has to manually check technician skills, hours, time off, job duration, conflicts, and travel before promising a customer a time.

I rebuilt that entire journey:

“Can you come?” → problem details → qualification → real feasible times → booking → “You’re booked.”

Behind that is Smart Slot Match, a deterministic scheduling engine that checks 9 real constraints before offering a time.

But the owner side is just as important.

The owner can add and manage technicians, assign their skills, define working hours, and mark someone as sick, on leave, or unavailable. Those changes immediately affect who can receive new bookings. The owner also gets a dispatch view and a Needs Attention queue for emergencies, delays, reschedules, and affected jobs.

Technicians can manage their jobs and report delays, while customer-impacting changes are tracked instead of happening silently.

The result is not another generic booking calendar. It is a complete workflow designed to remove the coordination burden from the owner while keeping every appointment realistic, explainable, and under human control.

Customer: gets a real appointment without back-and-forth. Owner: spends less time coordinating people, calendars, and exceptions. Technician: sees the right jobs and can report real-world changes.
