Success story · AI hotel management system · USA and Europe

Hotel PlatformEight engineers built an AI hotel platform with 1,000+ integrations, where competitors need 50 to 100 people

A next-generation hotel management system, under NDA, with AI in every part of running large and very large hotels in the US and Europe. It connects to more than 1,000 systems, from door locks to Wi-Fi management, so a hotel moves onto it without replacing anything it already runs. I am its fractional CTO and chief architect: the architecture and the concepts are mine, and I lead the eight engineers who build it. Competitors need 50 to 100 people for software this broad. My architecture lets a team of eight carry about 5 million lines of code and add a new integration in 1 to 2 days, where it used to take weeks.

The starting point

A large hotel runs on dozens of systems at once: reservations, front desk, door locks, Wi-Fi, housekeeping, billing and many more, each from a different vendor. Most hotel software was built before AI and connects to only a handful of them, and the staff fill the gaps by hand.

This platform is meant to be the next generation: one system with AI throughout that runs a large hotel end to end and connects to whatever the hotel already has, for the US and European markets. Software this broad usually takes a large vendor and a whole engineering department. Here it had to come from a small team, so the architecture decided everything.

What we did

  1. My architecture, my concepts

    I am the fractional CTO and chief architect. I designed the architecture of the whole system and the concepts it is built on, and the company gets a chief architect's work at a fraction of the cost of a full-time hire.

  2. More than 1,000 integrations

    The platform connects to more than 1,000 systems: hotel door locks, Wi-Fi management and everything in between. Name a hotel integration and it is there, so a hotel switches over without ripping out the equipment and vendors it already pays for.

  3. About 5 million lines, one coherent system

    The system has grown to about 5 million lines of code across different technologies and connectors. One architecture holds all of it together, and that is how eight engineers carry a codebase that usually needs a whole department.

  4. AI from the ground up

    AI is built into how the hotel is run and has been part of the system since the foundations were laid. Hotel software written before AI has to be retrofitted at great cost, and this platform will never need that rewrite.

  5. Built for the largest hotels

    The system is designed to manage large and very large hotels in the US and European markets: the properties with the most systems to connect and the most to save by running them from one place.

  6. Eight engineers instead of 50 to 100

    I lead the eight engineers who build it on that architecture. Competitors need 50 to 100 people for software this broad, and the company gets the same reach from a team of eight.

  7. A new integration in 1 to 2 days

    The connector framework I designed turns each new integration into routine work instead of a new project. Adding one used to take weeks and now takes 1 to 2 days, and that is how a team of eight keeps pace with more than 1,000 of them.

The result

The company is getting a next-generation AI system for large hotels, with more than 1,000 integrations and about 5 million lines of code, from a team of eight engineers, where competitors need 50 to 100 people for the same work. A new integration takes 1 to 2 days instead of weeks, and the architecture I designed is what makes eight people enough.

As fractional CTO I rebuilt how the product is made and run: development and testing went from 16 people to 3, the servers from 18 to 3, the cloud bill fell by 70% and errors in the mobile app by 97%. A task now reaches production in a day instead of 2 to 3 weeks, and the product ships three times a day at 99.99% uptime, a pace most in-house teams never reach.Read the story02MetizPromServiceMetalworking and parts manufacturing · KazakhstanFractional CTOA factory saves $300,000+ a year and halved its IT costs after two engineers I hired replaced its contractorsMetizPromService machines parts to customers' drawings in Kazakhstan. When I joined, contractors ran its IT and its accounting, production and lathe-control systems, and the company paid for outside software and licences. I built its own infrastructure, hired and trained two engineers, and we replaced every paid production system with an ERP and CRM of our own, with the ERP live in 3 months. The company now saves more than $300,000 a year on software, spends over 50% less on IT than the contractors cost, salaries included, and its CNC machines stand idle 23% less, with half as many unplanned repairs.Read the story03CV RocketJob search and AI CVs · USA and worldwideFractional CTOOne engineer and a fractional CTO took CV Rocket from zero to sales in five weeks and to 1,000+ customersCV Rocket writes a CV for one job posting in 15 to 50 minutes and brings the US and world job market into one place: more than 1.5 million postings from 89,000+ job sites.
