Über mich
Data analyst & SQL/database developer. I design normalized MySQL/PostgreSQL databases (schemas, roles, triggers, stored procedures) and turn messy data into clean, actionable insights using Python (Pandas, EDA, visualization) and basic ML models. Recent work: a star-schema data warehouse with a full ETL pipeline and a 4-model classification system (85% accuracy), plus a communal services database with 9 triggers and 11 stored procedures. New to Fiverr, not new to data — full projects in my portfolio. I scope carefully, communicate clearly, and deliver documented, working results.
