What I'm looking for

I'm open to remote opportunities.

At Seerist, I was the technical owner of migrating ~2 TB of historical data to Elasticsearch and S3, then migrating the platform to OpenSearch. The work reduced monthly infrastructure costs by about 30%, improved performance, and enabled ML plugins for Data Science.

I built ingestion pipelines for live and historical data and developed scrapers using sources defined by analysts and data scientists. I also migrated scraping apps to a monorepo, reducing proxy spending by ~10% and increasing daily runs from 1 to 4 for scrapers that required it.

At BlueTide, I developed a Ruby on Rails cooking platform with a payment gateway integrated with Panama's national banks, and built the MasMeDan application on AWS serverless services. I also integrate AI into my engineering workflow to analyze solutions, plan approaches, and review changes.
