Rodrigo Karim G.

I'm a data engineer working mostly on Google Cloud. Most clients come to me with the same problem: the data they need lives in five different places (a SaaS tool, a warehouse portal, a few spreadsheets someone updates by hand) and nobody fully trusts the numbers. I bring it together into BigQuery or PostgreSQL, model it with dbt or Dataform, and build the reports people actually open. On Upwork I've worked on inventory and order planning, sales and fulfillment data from Shopify, Amazon and a 3PL, marketing attribution from Google Ads, Amazon ads and Facebook/Meta Ads, a social media pipeline that uses AI to tag posts, and a production system for a gym that started as a spreadsheet. The industries change; the problems repeat. I'm Top Rated Plus with 100% Job Success over 2,200+ hours. One client wrote that I understand tradeoffs and long-term architectural decisions. In practice that mostly means saying early when something won't scale or when the data doesn't add up, instead of quietly working around it. Before data I spent eight years in manufacturing: five in engineering and maintenance, then three in Shanghai running procurement. I have an electronic engineering degree and an MBA, so I tend to ask about the business before the schema. I'm also finishing a degree in Psychology, which helps more than you'd expect when the dashboard is for people who don't like dashboards. Tools I use most: BigQuery, Python, SQL, dbt, Dataform, PostgreSQL, Cloud Run, n8n, Fivetran, Airbyte, Weld, Looker Studio, Google Sheets and Apps Script. I'm based in Argentina (UTC-3), with full overlap with US business hours.
