I make data
easier to trust.

I’m Carlos, a QA professional who has validated data pipelines, dashboards, and APIs, and worked as a QA Lead. I’ve also mentored others and supported customers. Now I’m studying Data Engineering to build on that foundation.

01THE THROUGH LINE

Quality is how
I approach data.

I’ve spent my QA career tracing data from pipeline outputs to dashboards—using SQL and Snowflake to compare results, investigate discrepancies, and check API responses. I also defined data-validation requirements and logic to make checks consistent.

I’ve taught others to notice QA details and ask better questions. In customer support, I learned to listen for what a customer is feeling so I can respond more helpfully. Now I’m learning to build the pipelines I know how to validate.
