Case Studies

A closer look at how I approach real automation and integration work — not just the outcome, but the actual problem and solution.

Live System

Multi-Platform Booking & Revenue Automation System

Short-term rental cleaning & property management — 34+ properties across Airbnb, Hostaway, Guesty, VRBO and Lodgify
iCal Sync WhatsApp Automation AI Routing
Airbnb / Hostaway / Guesty / VRBO / Lodgify
Self-Healing iCal Sync (35+ Feeds)
WhatsApp Alerts + Revenue Reports
Before
Cleaning schedules and revenue tracking managed manually across 5 disconnected booking platforms — stale data and missed cancellations were a constant risk.
→
System I Built
35+ iCal Feeds → Self-Healing Sync Engine → WhatsApp Team Alerts + Automated Revenue Reports
→
Result
Cleaning staff always work from a live, accurate schedule, and weekly revenue reporting runs itself.
The Problem

A property management business running 34+ short-term rental properties needed reliable, real-time visibility into bookings, cleaning schedules and revenue — without staff manually checking five separate booking platforms, and without a notification system so noisy that real changes got lost in the noise.

The Solution

Built a self-healing iCal sync engine pulling live booking data every 30 minutes from 35+ calendar feeds across Airbnb, Hostaway, Guesty, VRBO and Lodgify — filtering out platform-specific placeholder events and using stable event identifiers (not just dates, which can shift) to correctly detect real guest changes and cancellations. On top of that: automated WhatsApp reminders for cleaning staff (daily, weekly, and on-demand via chat commands), a lightweight change-detection layer that only alerts the team when something genuinely changes, an AI-powered system that routes incoming guest complaints from WhatsApp to the right place, and a direct Lodgify API integration that auto-generates weekly revenue reports with built-in safeguards flagging bookings with missing pricing data for manual review instead of silently showing incorrect figures.

Challenges Solved
  • Debugged and fixed 6+ distinct failure modes in a live production system — calendar sync bugs, date-conversion errors, Google Sheets API rate limiting, OAuth/SSL infrastructure setup (Cloudflare DNS + Let's Encrypt via Nginx Proxy Manager), and data reconciliation logic for guest-initiated booking changes.
  • Built a self-healing sync architecture — rather than a one-way data pipeline, the system continuously reconciles its own state against live source calendars, auto-correcting stale or incorrect records without manual intervention.
  • Diagnosed a third-party API data gap by comparing raw API responses against the platform's own CSV export — proving a genuine upstream limitation rather than assuming it was a bug in our own code — and designed the system to gracefully flag these cases for manual review instead of failing silently.
Built on the same foundation as my n8n + AI workflow automation, drawing on my workflow automation services and AI automation services. The API-data-gap investigation behind this project reflects the same approach covered in debugging & technical problem solving.

Multi-Platform Short-Let Property Setup

Property management automation — Lodgify, Airbnb, Booking.com, PriceLabs
Lodgify PriceLabs Automation
Guest Inquiry
Lodgify
PriceLabs API
Airbnb / Booking.com
Automated Messaging
Before
Manual setup across 4 separate dashboards — pricing and guest messages easy to get inconsistent.
→
System I Built
Lodgify → PriceLabs → Airbnb → Booking.com → Automated Guest Messaging
→
Result
Property live and synced across every platform without manual upkeep.
The Problem

A new short-let property needed to go live across four platforms at once — Lodgify, Airbnb, Booking.com, and PriceLabs — with consistent pricing, fees, house rules, and guest communication. Doing this manually across four separate dashboards risked inconsistent pricing and missed guest messages.

The Solution

Set up the property from scratch across all four platforms: synced pricing and fees through PriceLabs, configured automated guest messaging and house rules, built a parking registration workflow, and mapped amenities consistently everywhere a guest might see them.

Delivered as a single Upwork engagement: full multi-platform property setup from scratch.
Built with the same integration approach behind my n8n automation work.

WooCommerce to Customer.io Integration

E-commerce customer data sync and automated messaging
WooCommerce Customer.io Integration
Order Placed
WooCommerce
Webhook
Customer.io
Triggered Email
Before
Manual CSV exports and spreadsheet imports every time a new order came in.
→
System I Built
WooCommerce → Real-Time Sync → Customer.io → Triggered Email Campaigns
→
Result
Emails fire automatically based on real purchase behavior, no manual uploads.
The Problem

An online store needed customer and order data flowing from WooCommerce into Customer.io to power automated email sequences — without manual exports or spreadsheet imports every time a new order came in.

The Solution

Built a direct integration syncing customer profiles and order events from WooCommerce into Customer.io in real time, so triggered email campaigns fire automatically based on actual purchase behavior instead of manual list uploads.

Migrating Off a No-Code Platform: Base44 to Self-Hosted

AI app platform export, audit, and independent server deployment
Base44 Migration VPS Deployment
Base44 App
Export & Audit
Self-Hosted Server
Replicated Backend
Before
No inventory of what the app depended on — locked into a no-code platform.
→
System I Built
Base44 Export → Full Audit → Self-Hosted Server → Replicated Functionality
→
Result
Independent infrastructure with the same functionality, no no-code dependency.
The Problem

A language-learning app built on Base44 (a no-code AI app platform) needed to move to independent, self-hosted infrastructure — but the client had no clear inventory of what the app actually depended on: which data tables, AI features, file storage, and server-side logic would need to be replicated.

The Solution

Exported the complete project and delivered a written inventory of everything it used — data tables, content, AI features, file storage, and server-side logic — the exact map of what needed to move. Then set up the server and backend independently, replicating the platform's functionality without the original no-code dependency.

"Milestone 1 — Export & Full Audit: I export the complete project from Base44 and deliver a written inventory of everything it uses: data tables, content, AI features, file storage, and server-side logic — the exact map of what's moving to your server."

Building a WhatsApp AI Chatbot with Automated Follow-Up

Customer-facing conversational bot with a built-in retention sequence
WhatsApp Business API Chatbot Automation
Customer Message
WhatsApp API
AI Chatbot
Follow-Up Engine
Before
Every customer message needed a manual reply — quiet conversations were lost for good.
→
System I Built
WhatsApp Business API → Chatbot → Automated Follow-Up Sequence
→
Result
Conversations run themselves and automatically re-engage customers who go quiet.
The Problem

A business wanted to handle customer conversations on WhatsApp without a person manually replying to every message — and needed a way to re-engage customers who went quiet mid-conversation, rather than losing them silently.

The Solution

Built a WhatsApp Business API chatbot handling the core conversation flow, plus a separate automated follow-up sequence that re-engages customers who stop responding — turning a one-shot chatbot into something that actively works to bring conversations back to life.

Delivered in two milestones on Upwork: the core chatbot build, followed by an automated follow-up sequence for customer re-engagement.

Shopify Store Configuration & Custom Feature Build

App settings audit and a custom per-variant notification feature
Shopify Shopify Apps Custom Development
Storefront
Shopify Apps
Settings Audit
Custom Notification Build
Before
App settings misconfigured; back-in-stock alerts only worked at the product level, not per variant.
→
System I Built
App Settings Audit → Fix → Custom Per-Variant Notification Build
→
Result
Customers get notified for the exact size or color they were waiting on.
The Problem

A Shopify store needed its installed apps checked and correctly configured, plus a specific storefront feature — a "notify me when back in stock" button — that only worked at the product level, not per variant, meaning customers couldn't be notified about the specific size or color they actually wanted.

The Solution

Verified and corrected the store's Shopify app settings first, then rebuilt the back-in-stock notification button to work per variant — so a customer waiting on one specific size gets notified for that size, not every variant of the product.

Two separate Upwork engagements with the same client: a Shopify app settings verification, followed by the per-variant notification feature build.
Similar work is covered in my Shopify API integration guide, part of my Shopify automation services.
