I build reliable AWS lakehouse platforms processing millions of records with Spark, Delta Lake, and dbt.
BrazilWhat I'm looking for
I've built and operated data lakes for LicIA, an AI-powered public procurement intelligence platform, processing 7,000–9,000 files daily into approximately 20 governed AWS Glue tables for internal teams and customer dashboards.
I improved production reliability by correcting SQS visibility handling and replacing non-atomic Redis batching with Lua operations, eliminating 2–5 silently dropped events per day and sustaining zero observed losses for four months. I also led a 14-configuration OCR benchmark across 400+ pages, reducing character error by 55% and improving table-structure accuracy by 21%.
For RBOOH, I delivered a Polars, Delta Lake, FAISS, dbt, and Spark pipeline in seven weeks that produces approximately one million deduplicated listings per run across 108 cities.
I've also led the architecture for Phytoflow, building Terraform-managed AWS IoT Core infrastructure and a serverless Lambda-to-S3 telemetry pipeline with partitioned Parquet data and AWS Glue cataloging.
