Experience

Content Repository

An active repository to store content and metadata related to it. As the software architect, I developed most features of the solution using Java. The solution relies on HBase and HDFS to store the data and uses Apache Solr to index data and allow low-latency searches.

This repository's main requirements included high availability, fault tolerance, and low latency. This was built to replace a legacy solution that was using a traditional file system and database. The repository also offers schema management and evolution to allow each application to store the metadata relevant to its business.

Payment Cloud Platform

A cloud-native payment platform built on top of Azure. I was the main data platform architect. I defined the technologies and developed frameworks, libraries, and tools used by other data engineers.

The data platform allows the ingestion of data using CDC on top of MongoDB, events from Kafka, and any file. It also allows processing data through streaming or batch processing with Spark running on Databricks or Kubernetes.

Supply Chain Management Analytics Platform

An analytical platform for supply chain management. As the main architect, I did the environment dimensioning, defined the technology stack, and developed numerous critical components of the solution.

The platform's goal was to replace a legacy BI solution built on top of Microsoft Integration Services (SSIS), reducing our operational costs and providing more analytical capabilities to improve the replenishment time of our customers.
