Data & AI · Bali, Indonesia
Hi, I'm Fachrul
Most analysts read the data. I build the systems that make it exist, flow, and mean something.
Driving analytics, automation, and AI in hospitality.
About Me
Numbers and logic just made sense to me growing up. I studied Statistics at Universitas Brawijaya — the computing-heavy track — so I spent a lot of time with R, Java, and C before I touched real data.
When I started my first job and picked up Python, something shifted. I was solving problems that mattered to real people, not just coursework. That's when I stopped thinking of it as a career and started thinking of it as a craft.
I like building things. A pipeline that runs cleanly every morning, a dashboard someone opens before their coffee, a model that changes what decision gets made — that's what keeps me interested.

Things I've Shipped
Enterprise BI Platform
LiveMetabase for 300+ people across Sales, Revenue, Finance, F&B, Spa, Banquet, Guest Recognition, and other operational teams. 200+ dashboards, ~100 daily active users. If a dashboard breaks, someone notices within the hour. Currently migrating the whole thing off MSSQL.
Data Pipeline Infrastructure
Live50+ Airflow DAGs pulling from 15+ source systems — Oracle PMS & POS, SAP, spa, loyalty, booking engine, guest surveys, Google Ads, and more. Processing millions of records daily. Includes scheduling, monitoring, and failure recovery — keeping the data flowing across the whole operation.
Guest Chat AI
LiveRAG-based chat assistant deployed across 5 properties — answers guest questions about rooms, amenities, dining, and services in real time. ~1,500 conversations/month with up to 98% accuracy. Backed by a property knowledge base in Vector DB, served via OpenAI.
Website Booking AI Agent
LiveConversational AI agent on the hotel website — helps visitors explore properties, compare options, understand promos, and navigate to booking. ~1,200 conversations/month with up to 95% accuracy and a 7% conversion rate. Handles pre-booking questions that used to go to human support.
Multilingual Ops Chat Translator
LiveGuests message concierge in their native language — Japanese, Chinese, Korean, or English — through the hotel app. The ops team sees everything in English on their dashboard. ~70K messages/month. No language barrier, no delay.
AI Analytics Enrichment Pipeline
LiveAn Airflow-integrated pipeline that runs AI daily over guest feedback — categorizing complaints, summarizing stays, inferring preferences, and surfacing activity recommendations. Processes thousands of records daily. Turns unstructured text into structured insight.
Occupancy Forecasting Model
LiveA model to forecast hotel occupancy from historical booking data. Current MAE of 16 room nights at D-14. The output feeds directly into daily worker hiring and revenue pricing decisions — so getting it right actually matters.
Guest Data ETL & Segmentation
LiveYears of guest profile data, cleaned and deduplicated. Then segmented by behavior to support marketing and the loyalty program. Turned a mess of raw records into something the business could actually act on.
Personal Financial Tracker
LiveMy own thing — Google Sheets → PostgreSQL → Metabase, running on this server. Built it because I wanted a clean view of my finances without paying for another SaaS tool.
