about Justin mullis
Why hello! I’m Justin Mullis, a Senior Database Operations Engineer based in London, Ontario, Canada with close to a decade of experience. I specialize in designing and implementing robust, scalable, and high-performance solutions within the Azure ecosystem, focusing on ETL/ELT pipelines and SQL Server databases.
With a passion for implementing robust error handling, ensuring performance and solving complex challenges, I empower organizations to unlock the full potential of their data.
What I Do
My professional journey has taken me through diverse roles, including Software Developer, Systems Administrator, Database Administrator, Database Operations Engineer, and now, Senior Database Operations Engineer. This breadth of experience has provided me with a well-rounded perspective and a deep understanding of the data and software landscape.
Currently, I dedicate 70% of my time to creating and maintaining ETL/ELT data pipelines, ensuring data flows are seamless, scalable, and efficient. The remaining 30% of my work focuses on database administration, where I optimize performance of SQL code.
Beyond technical work, I collaborate closely with DBAs, mentor data analysts, and partner with software developers to deliver cohesive and effective solutions.
My Tech Stack
I’m highly skilled in Azure tools and platforms, including Azure Data Factory, Data Flow, Python, SQL Server, Azure SQL Database, Azure Managed Instances, data lakes, and Logic Apps. My standout skill is T-SQL, where I excel in crafting optimized queries and solving complex database challenges with precision.
beyond work
When I’m not engineering data solutions, you’ll find me reading (Fantasy novels are my go-to!) watching anime, staying active at the gym, or escaping to the great outdoors for some camping adventures. I also enjoy tackling home renovations.
Who knows - I might even blog about some of these experiences too!
