Cloud Data Architecture

Cloud Data Architect / Lead Developer Snowflake Snowpipe Snowpark ...
Cloud Data Architect / Lead Developer
Setting up an architecture using Snowflake, DBT and Airflow inside the current Azure Cloud replacing the current implementation an External Application Design Engine.
In the new architecture, we incorporated the existing delivery of data coming an Apache Kafka message service, Web APIs and Sharepoint by setting up the automatic loading in Snowflake using Snowpipe. In Snowflake we have setup the CDC using Streams options of Snowflake to keep the workload as lean as possible.
DBT is used to define all the transformations, documentation, test and automation by using macros. For the different brands within Amer Sports, like Salomon, Peak, Wilson and others, we have introduced the use of Row Level Security, so that they can only see their own data. In addition to that we also implemented a second level of Row level Security on countries within a brand.
For each brand we have setup environments for each brand and giving them guidelines how to use Snowflake, DBT, Airflow and Azure. The environments have the same structure as the environments for Amer Sports.
In close corporation with Wilson and Salamon we have set the quality of data to a higher level by integrating historical data.
Added models for monitoring the costs on warehouses and cloud services from Snowflake. As a pilot to see how to use Snowpark and Streamlit together, I wrote some Python script to make a model of the costs showing it in a dashboard.
Additional responsibilities:
  • Data modelling using facts and dimensions, fading out data vault
  • the redesign and implementation of the roles in Snowflake
  • the setup for the use of warehouses in Snowflake
  • the setup of DBT
  • the setup of Airflow jobs and configuration of the jobs
  • guiding the development team
  • planning of issues and resources
  • guiding the business teams from the brands

Data Information Architect & Cloud Consultant
One of the projects is a BI Portal for companies to send the data to us and we deliver all the analytics that can be done on that data.
For this project we use a combination of different cloud suppliers as AWS and GCP. For the data storage we use now Snowflake but also looking at Apache Druid. For the continuous delivery of data, we are building a combination of Snowpipe and/or Apache products in combination with AWS Lambda.
For ETL/Scheduling we are evaluating Airflow/Python, Apache Nifi and Talend Open Studio. For the analyses we use Apache Superset as it is very flexible.
As a part of investigation of using Matillion as an ETL tool I have setup an own Matillion instance to look at the integration of Git with Matillion using the different environments and the use of all the different kinds of variables. One of the shortcomings is that grid variables have a limit of 5000 items.
As part of investigation for the front-end I am using S3, Hugo and React to publish static and dynamic sites.

Setting up an architecture using Snowflake, DBT Cloud inside the current AWS Cloud for data quality monitoring and financial reporting on PowerCloud data.

In the architecture, we incorporated the data coming from PowerCloud using stages of Snowflake and macros in DBT Cloud. In Snowflake we have setup a data model and business rules to show customers of PowerCloud the level of errors and reporting on their key figures. The project is an ongoing development to deliver several products for customers of PowerCloud

Additional responsibilities:

  • Data modelling using facts and dimensions 
  • the design and implementation of the roles in Snowflake
  • the setup for the use of warehouses in Snowflake
  • the setup of DBT
  • guiding the development team
  • guiding the business team

I also gave a course in understanding and using Snowflake to a group of 8 people of WTS to get them ready to earn their first Badge in the certification line of Snowflake.

Data Information Architect
Make a study to how the data warehouse Maps can be innovated. Old software used like Oracle Warehouse Builder and Talend Open Studio were no longer supported. Also the performance of getting data from the SAP and processing it is really slow.
The first option was to rebuild all logic and use Cloud technology. Due to the kind of data in combination with security issues the Cloud had to be avoided. The solution will be based on reinventing on-premise. One part of the solution is to let the SAP system send data using asynchronous calls. The second part of the solution is by reengineering as much as possible the current used software.
In the process we have 3 competitors of which Trivadis has the best option while they can convert all the Oracle Warehouse Builder definition. The extraction and sending of data is in research by the SAP teams.

The BowTie application is a visual application which shows the statuses of components in the physical energy network. Helping to setup the test use cases and guiding the user tests.
Investigate for a proof of concept of Asset Event Register to determine several KPIs from data transferred from the old data warehouse to the new data warehouse in Snowflake and the way to go. Defining business rules which can be adapted by the business for developing other KPIs.
Exporting the Carmen data warehouse and Matillion jobs in Redshift and the Matillion jobs to Snowflake using export and import tools of Matillion. After the import corrections were made to let all components work again (Redshift components have other properties than Snowflake components).
All Matillion jobs were divided in shared and the normal jobs using the shared jobs.
