A bit about me

I'm an industrial engineer from Santiago who fell in love with turning messy data into clear decisions. I started in financial services (pension and retirement analytics at Principal), moved into heavy-equipment telematics, and most recently worked on churn analytics in telecommunications.

I enjoy the whole path: SQL pipelines and statistics at the bottom, models and experiments in the middle, and dashboards that people actually use at the top. I like projects where a number changes what a team does tomorrow, such as who to call first, which KPI to trust, or which machine to service.

Right now I'm based in Perth, Australia, looking for my next data analyst, business analyst or data science role, ideally in financial services, banking or fintech.

Finance is a long-term interest, not just a sector: I manage my own diversified long-term portfolio, and I'm exploring how automation and AI can help small businesses through a prototype called Lumora.

Outside work: football (soccer), motocross and snowboarding. I like fast feedback loops, on and off the screen.

Experience

Click a role to see what I did.

    • Built an automated BigQuery pipeline that detects competitor calls and measures 5-day port-out risk across ~700k daily calls, with Looker Studio reporting for management.
    • Identified segments with 4-6x higher churn probability, enabling retention outreach to ~600 customers per day.
    • Segmented customers by churn risk and ran A/B tests (control vs treatment) to measure retention campaigns; found conversion differences of up to ~35% between segments.
    • Automated churn, behaviour and competitor reports, cutting analysis and execution time by up to ~65%.
    • Redesigned a low-quality sales KPI (67% precision, 9% recall) with a decision tree, proposing rules with 91.5% precision or 33% recall.

Let's talk data

I'm looking for my next data analyst, business analyst or data science role in Australia, especially in financial services. If you have a team that needs someone who can go from SQL to stakeholders, I'd love to hear from you.
