		`Location: Brazil (UTC-3, overlaps US hours) Remote: Yes Willing to Relocate: Yes (US preferred) Technologies: SQL Server, DBT, SQL Mesh, PostgreSQL, SQL, OLTP & OLAP, cloud optimization, query optimization, large-table migrations, F#, Clojure, Python, C#, C, Java, Ruby, Rust, Prolog, OCaml, Haskell Email: ebellani at gmail` I specialize in rescuing and scaling PostgreSQL systems that have become bottlenecks due to schema debt, growth, or operational complexity. Recent work: re-architected two multi-terabyte OLTP tables (~2TB and ~1TB) handling 200+ writes/sec, improving scalability and reducing application-level complexity. My work focuses on high-risk database migrations, dangerous schema remediation, hot-path optimization, and making existing systems scale without rewriting the product. Open to consulting or full-time roles where data is central and performance matters.
