What I'm looking for

I seek a data engineering or analytics role focused on building scalable, well-tested data platforms, automation, and cross-functional collaboration in teams that value data quality.

I am a Senior Data & Analytics Engineer with broad experience building ELT pipelines, data modelling, and observability across cloud platforms. I focus on delivering reliable, well-tested datasets and self-service analytics that empower business teams.

At TELUS Digital I developed infrastructure-as-code pipelines (Pulumi) and refactored templated configs, led migration of legacy dashboards into GCP, and introduced a SQL Style Guide enforced via SQLFluff to improve developer productivity.

Previously, I rebuilt dbt models for a Stripe migration at Toggl, optimized ELT scheduling to reduce lead time by 40%, and implemented extensive testing for MRR models. At Nubank and earlier roles I reduced redundant datasets, deployed bespoke SQL tests, and supported cross-team analytics using Spark/Scala, Power BI, and Qlik.

I mentor engineers, conduct technical interviews, and hold the Google Professional Data Engineer certification; I seek to join teams that value data quality, automation, and clear operational practices.
