I build reliable data, retrieval, and AI platforms at production scale.

What I'm looking for

I’m open to remote opportunities in AI Engineering, Search Engineering, ML Infrastructure, Retrieval Systems, and AI Platform Engineering, where I can build reliable, observable, cost-efficient retrieval and data systems for production AI.

At Nubank, I own the data and measurement layer for engineering productivity and AI adoption across 11,000+ employees and 10+ AI development tools. I build the governed pipelines, metrics, dashboards, and OKR tracking that give leadership a single source of truth for AI’s impact.

I’ve solved difficult data-integration problems by building a record-linkage model that raised coverage from 64.7% to 96.4%, eliminated manual mapping, and improved business-unit accuracy to 86.8%. I also redesigned productivity metrics using millions of activity records and am leading the migration of AI-usage data into a tested, monitored Scala pipeline with lineage.

Previously at Nubank, I built and scaled the engineering-productivity data platform, largely as the team’s sole data engineer. My work cut recovery time from about an hour to 13 minutes, doubled refresh frequency, reduced dashboard load times from 27 to 7 seconds, and brought Jira desynchronization down from 6.53% to 0.36%.

I’ve also built analytics and growth data systems at QuintoAndar, taught Statistics, Data Visualization, and Advanced SQL, and authored a full 170-hour data-analysis curriculum for Instituto Joga Junto. I’m pursuing graduate studies in Information Retrieval and Vector Databases, focused on the indexing, retrieval, and RAG layers behind production AI systems.
