Bernard

I am a Junior Developer/Intermediate Database Engineer with 4 years hands-on experience in SQL, Big Data and database systems, working with large-scale ClickHouse and PostgreSQL environments on a live telecommunications platform. I enjoy working directly with data, improving performance and finding practical solutions to complex problems. I am experienced in ETL, dataflow automation, SQL optimisation and customer-facing support, including SLA-driven environments.
