Hospitality Software Development Services — Hotels, Multi-Property Groups & Vacation Rentals

Hospitality runs on a tangle of decades-old PMS, channel managers, payment processors, in-room devices, and CRMs — most of which were not designed to talk to each other cleanly. DiveScale ships hospitality software that respects the tangle: deeply tested PMS integrations with Mews, Opera, RMS, and CloudMailin; backends that survive vendor outages and quirky webhooks; and guest experiences that work on real hotel Wi-Fi.

We have shipped end-to-end hospitality platforms in production — not just slide-deck reference architectures. Our stack: NestJS for the API tier, Next.js (App Router with Server Components) for guest-facing and ops-facing UIs, AWS Lambda for event-driven workloads, and Terraform across the whole AWS estate so multi-property, multi-region rollouts are reproducible rather than manual.

On the AI side, our concierge agents are grounded in real property data using a RAG pipeline orchestrated with LangChain and LangGraph. We design the tool surface carefully: front-desk-safe actions only, refusal patterns when uncertain, multilingual coverage, and an audit trail every property manager can review. Hallucinations get caught by evals before they reach guests.

We treat the device fleet as a first-class problem. In-room iPads, kiosk tablets, and back-of-house Macs are managed via Jamf — zero-touch enrollment, kiosk mode, content pinning, and remote remediation. Front-desk and housekeeping never become unpaid IT support.

Marketing and stay-creative pieces are handled through embedded IMG.LY editors so hotel teams produce branded assets — room photos, promo banners, OTA hero images — without waiting for a designer or learning Photoshop. We integrate the editor with your DAM, fonts, and brand templates.

Operationally we cover the parts hospitality teams ask about three weeks into a project: GDPR-aligned guest data handling, PCI tokenization through Stripe or Adyen, mobile keys, contactless check-in, and the boring-but-critical reporting tools revenue teams live in. We build the seams properly so the rest of the platform inherits the discipline.
