Hire Software Developer for HVAC
Senior, direct, no layers

An HVAC business juggles three different kinds of work at once: urgent call-outs that cannot wait, installations that take days and need the right crew and equipment, and maintenance visits that recur on contracts. When those three share one diary and one stock record badly, a call-out steals a technician from an install, a maintenance visit is forgotten, and a van arrives without the part the job needs. The diary looks full, but the work does not flow.

This engagement builds one HVAC firm's own system: customers, sites, jobs, contracts, and van stock for that firm alone, not a marketplace for trades and not a consumer booking site. It separates call-outs, installs, and maintenance into job types with their own scheduling rules, holds each customer's equipment and service history per site, and tracks van stock against the jobs that will consume it. Supplier ordering tools feed it; they do not replace the firm's job record.

The natural first slice is job scheduling itself, because diary clashes are the failure customers feel first. Book a free discovery call and the fit is tested on a real week of call-outs, installs, and maintenance visits, with the scheduler describing where the current diary breaks.

HVAC scheduling has to respect skills, geography, and van contents at the same time, so the scheduling view shows all three: which technicians hold which qualifications, where they are, and what their vans carry. That is a harder view to build than a simple calendar, and it is the view that makes the system worth using, because a calendar that ignores skills and stock will be ignored by the scheduler. Field screens are kept to the job, the site, and the equipment, so a technician on a roof or in a plant room can work from a phone without office clutter.

The pilot runs on one team or one job type, with the old diary kept alongside until the new schedule matches reality on live jobs. The firm owns the code, the data, and the hosting, and job and contract histories export in readable form.

When the system works, the diary stops being a source of clashes. Call-outs go to technicians who can actually fix the fault, installs are planned as multi-day work with their crews and materials, and maintenance visits happen on schedule because contracts generate them. The scheduler's week gets calmer, van stock surprises fall, and customers hear realistic arrival windows because the schedule behind them accounts for skills, location, and stock.
