What I'm looking for

I’m looking to build reliable data platforms and pipelines that enable Data and AI, working with a team to solve business problems and continuously improve systems end to end.

I’m a Data Engineer building end-to-end data engineering projects—from orchestration and ingestion to transformation and visualization. I enjoy turning messy inputs like web scraping results, REST APIs, and CSV files into reliable data products that teams can actually use.

In my recent roles, I’ve worked extensively with Google Cloud Platform, using BigQuery, Composer, GCS, Dataflow, and Dataproc (Spark). I’ve also delivered cross-platform pipelines using Informatica IICS and AWS Redshift, and contributed to low-level design work to extend existing data models.

For transformation and analytics workflows, I’ve used dbt and Snowflake, along with PySpark and Informatica IICS mapping tasks. On the BI side, I primarily use Metabase to support data visualization and decision-making.

Before pure data engineering, I built machine learning solutions and predictive models as a Machine Learning Engineer, including sentiment analysis and image classification (82% accuracy). I’m proactive and passionate about challenges involving Data and AI, and I like working in teams to generate improvements by solving business problems with my ideas.
