what I work with

  • SQL
  • dbt
  • BigQuery
  • Snowflake
  • Databricks
  • Python
  • Terraform
  • GCP
  • AWS
  • Airflow
  • Fivetran
  • Looker
  • Power BI
  • Streamlit
  • RAG and agents
  • MCP servers

Ingestion from systems never meant to be read from, dbt models that survive finance, tests that block bad deploys, and lately the AI layer on top. Three of these are on the work page.

Four roles in four years, plus time on the hiring side, is what Upstream is made of.
