Highlighted projects

Big Data

Design and implementation of PoC for an ambitious project in the field of data catalogs. This project has been developed on top of Amundsen, Apache Atlas and Apache Ranger. The PoC was build by expanding Amundsen on top of Docker compose.

The objective of the project is to ingest metadata from all kinds of data origins. This includes relations databases, datawarehouses, any other kind of database, data files and media such as videos, audio or images.

Data Catalog Architecture
Big Data

Architecture design and implementation of a Big Data system in AWS for processing daily electricity consumptions in Red Eléctrica de España. This involved AWS Glue, EMR, Lambda, Pyspark, Zeppelin, Redshift, Spectrum, SFTP and S3.

The solution runs on demand batch jobs to apply the required transformations in data ingest in a Redshift data warehouse. The solution only runs when new files arrive to the landing zone and runs on transient clusters saving up to 80% of costs.

AWS Data Pipeline
Big data

Project aimed to create an online platform for clinical and molecular data retrieval. The online platform also includes a functionality to analyse molecular data stored in the cloud. The context of the project is in a biomedicine company that wants to provide to clients and to potential clients with a tool to explore the available data.

Building trust and confidence

Youtube Channel

DevOps + Data + AI

I advocate for the use of Cloud Native projects because they are of high quality and very compatible technologies. Their use can make to companies to get huge savings in comparison to use cloud PaaS solutions. 

I’m also very keen on promoting use of free libraries for Big Data storing and computing as well as for dealing with Deep Learning models. I bet on these technologies because their community is huge and because they are more likely to avoid the vendor locking problem.

You’ll always find in my channel tutorials for the latest technologies that are going to prevail in the market for years. I only recommend what I’m sure it will be best for my clients after I already have made tests and PoCs.
