At an education-sector company, I improve SQL Server queries that affect system performance, achieving 15% to 50% performance gains in most cases. I also built an automation that prepares database changes for production release and sends an email when the consolidated release file is ready.

I spent two years on a system migration project following a brand merger, building data migration flows with Kafka and ksqlDB and integrating accounting systems with Totvs. I also carried out business analysis for the CPA institutional student satisfaction survey, building reports used over a long period and supporting the BI team with dashboards.

At UnimedCampoMourão, I developed BPM processes modeled in BPMN, rolled out a collaborative intranet, and built custom SQL Server reports for departments. I also supported users and administered software platforms and business systems.

Outside work, I build and ship web applications that are running in production, including BlitzPicks, ArenaPicks, and PokeData. I use TypeScript, Supabase, and PostgreSQL across my projects, and am pursuing a degree in Digital Design and User Experience.
