Great work from David building our data platform. He is responsive and reliable. He went into the detail of our data so that the analysis lets us make the right decisions.
During our platform migration, David was a great help in setting up our data warehouse. With tools such as BigQuery, Airbyte and Tableau, our whole data aggregation and visualisation system was redesigned and made available to operational teams in a short time.
I worked with David on IoT data flows in an Azure architecture. He shared his expertise, notably by setting up a SQL database and processing functions inside it, so the data could be stored and served to our colleagues. We also used Azure IoT components such as Event Hub and Stream Analytics. David is very approachable, flexible and responsive. He adapts what he says to each audience so they get the right message, and he brings them up with him.
I worked with David on many complex database-processing problems to build scoring algorithms that refined my client's CRM strategy. He has strong technical and interpersonal skills and is very reliable and flexible. He brings his own vision to go further and improve whatever can still be improved. We worked together for more than two years, which shows his commitment and how much I enjoyed working with him.
I would highly recommend him to any public entity or enterprise in need of an expert with both deep technical skills in Microsoft environments and a customer-oriented approach that takes the human factor into account. Factually, he delivered on time and on budget.
A very effective partnership. Very good understanding of the issues and what was at stake. Strong SSIS skills.
He listens closely, learns a company's know-how in a few days and builds custom solutions that are realistic, smart and well sized. He communicates very well with teams, is patient and a good teacher, and never pushes you to spend more. Warmly recommended.
The project was run seriously from start to finish. Strong technical skills went hand in hand with great teaching in front of a non-technical audience.
I worked with him for four years at Groupe Marmara – TUI France. He is a dedicated and efficient engineer. We worked together on the internal fraud tool, the yield project and the company's websites.
Excellent S3 data lake architecture in a medallion layout, with AWS Glue, Data Catalog and Redshift for the silver transformations. Step Functions orchestrate the crawlers, the Glue jobs and the materialised-view refreshes, then launch the ML model on SageMaker. — Christine

David stepped in to unblock us on setting up a Snowflake and Power BI environment, through workshops that combined training and hands-on implementation.
