At SóCarrão, I build and modernize backend systems for a large-scale automotive marketplace, working across architecture, performance, data migrations, integrations, and event-driven solutions.
I reduced vehicle indexing from 15 minutes to 300 milliseconds with an AWS SQS, Lambda, and OpenSearch pipeline, and cut high-traffic PostgreSQL query latency from 2 seconds to 300 milliseconds. I also migrated 20 years of production data covering approximately 2 million users and 50,000 vehicles.
Previously at Auto Center Corujão, I independently built an inventory and cash-flow system for daily shop operations, consolidating a multi-spreadsheet workflow and reducing product registration from 10 minutes to under a minute.
