Open Gateway footprint

The ~90 Open Gateway adapters report from 4 countries — Spain plus three more on the board. The exact roster stays behind the firewall; the counters don’t lie.

Data Science roots

2019 · Data Science roots — Bible Text Analysis: scraping, NLTK, LDA topics and sentiment over a raw corpus. Provenance, not a headline.

The rest of the toolbelt, kept where it was used: Kubernetes and AWS CDK/CloudFormation from platform and deployment work; Cassandra and Snowflake at Zitro’s betting platform; RabbitMQ in event pipelines; pandas from the 2019 Data Science years. Listed by engagement, not as résumé soup.
