About Bogdan
Oracle SQL Developer | Query Performance & Reporting
Bucharest, Romania - 3:39 am local time
I spent more than six years working extensively with Oracle SQL in enterprise environments, including several years as a Senior SQL Database Administrator, where I acted as a technical reference for database teams, optimized complex queries, expanded large‑scale reporting systems, and supported critical business processes. My work involved performance tuning, data integrity, automation, and maintaining high‑quality, well‑documented database solutions.
I currently work as a Software Developer at VOIS Romania (Vodafone Romania Technologies), contributing to the development and optimization of complex software solutions used by enterprise clients worldwide. My focus includes SQL and PL/SQL development, query optimization, performance analysis, and improving existing and legacy database logic.
I am used to working with distributed international teams, production‑grade systems, and clear delivery expectations. I value precise communication, realistic estimates, and clean, maintainable solutions.
I am especially well‑suited for Oracle SQL development tasks, performance tuning, reporting, and targeted database optimizations.
