Marcello Da Silva Lopes

I’m a Senior SQL Server & SSIS Data Engineer with over 8 years of experience delivering scalable data solutions across gaming, finance, and healthcare.

I’ve worked with organisations including FDJ (formerly Kindred Group), GAN, Landesbank Baden-Württemberg, and the NHS, supporting production environments handling millions of records. My work has focused on building reliable ETL pipelines, optimising SQL Server performance, delivering reporting solutions, and supporting mission-critical systems in regulated environments.

Highlights from my career include leading the migration of over 2 million customer records using SSIS and T-SQL, improving ETL reliability by 25%, reducing query execution times by up to 40% through indexing and optimisation, and automating data ingestion and reporting workflows to significantly reduce manual effort.

My core technical strengths include:

• SQL Server development (T-SQL, stored procedures, performance tuning)
• SSIS ETL pipelines and data migrations
• Reporting (SSRS and Power BI datasets)
• Data warehousing (Star Schema / Kimball methodology)
• Production support and troubleshooting

I enjoy working on data platforms that solve real business problems, particularly in environments where data quality, compliance, and performance matter. I’m a strong collaborator and have experience mentoring junior engineers through code reviews and best practices.

I’m currently seeking remote Senior SQL Developer/ Data Engineer or ETL-focused roles, either permanent or contract, where I can contribute to building reliable data systems while continuing to grow my cloud and analytics skillset.
