Master Vacation Homes · Kissimmee, FL

Software Engineer

Second engineer at one of Florida's largest vacation-rental companies. I lead development of the internal property management platform, build the financial systems that audit every payout, and brought the company's AI in-house: a private LLM server and a guest-reply assistant that verifies its own answers.

Orbi · Property Management SaaS

Co-Founder & Lead Engineer

A multi-tenant SaaS for vacation-rental companies, from the first table of its 241-table data model to the 157-page admin I shipped personally. Employer-aware side venture, separate stack and codebase.

Full-Stack Developer

Co-designed a multi-tenant omnichannel support platform unifying WhatsApp lines and web chat into one real-time agent inbox, and built its entire frontend. Still in production 3+ years later.

Work I'm proud of

Three systems, all in production or headed there.

Orbi

The full operating system for US vacation-rental management companies: reservations, owner finances, housekeeping, and distribution to 60+ booking channels. Multi-tenant from day one, with a financial engine built around US trust-accounting rules: double-entry owner ledgers, payout batching, and reconciliation that matches what channels promise against what lands in the bank.

Financial automation & in-house AI

Reconciliation engines auditing millions in monthly payouts, where every automated change previews first and verifies against the source of truth. Plus a private LLM server on dedicated NVIDIA hardware and a guest-reply assistant that drafts from real conversation history and checks its own output.

Omnichannel support

Every WhatsApp line and website chat unified into one real-time agent inbox with department queues, typing indicators, and read receipts. I co-designed the architecture and built the entire frontend, including a widget that installs with one line of code.

How I work

Fast, without breaking things that matter.

AI-native

Claude Code, agents, MCP, and LLM APIs are my daily toolchain, always paired with the judgment to review everything they produce.

Safe with money

Every automated write previews its changes first, verifies the result against the source of truth, and ships with the tests to prove it.

End to end

From the first table of the data model to deployed, monitored, self-healing systems running in production.

Stack

Tools I ship with, daily.

Core: TypeScript end to end, React/Next.js on the front, NestJS behind it, Prisma over MySQL or Postgres.
AI: LLM APIs, retrieval, agents, and self-hosted inference, shipped to production, not prototyped.
