About Ismael

Hello!

I am a data enthusiast, I love translating business problems into data and ensuring that all profiles can understand how and why data can generate value.

I consider data quality important at all stages; not taking it into account can ruin the entire workflow. Furthermore, it's great to quantify the value that data projects generate, creating transparency and trust in what we do.

Regarding technical aspects, I have worked as a Data Scientist for about 11 years, with intermediate stages as a BI analyst, and working closely with engineering colleagues on developments in Spark and the Cloud.

Speaking of model types, I have focused on Machine Learning, supervised and unsupervised, with projects centered on linear and non-linear regressions, time series, clustering, and classification.

I have worked in Agile and Kanban, with the Atlassian ecosystem as tools and Git for version control.

Thanks for reading!
Best regards
