Jacob in a few words

👋 Director level software engineer, data engineer, and data analyst. Nearly 10 years of experience as a technologist inside early stage health tech companies. I enjoy being a part of high impact teams using technology to have real world business impact.

🧳 I'm excited to
- Work in full stack environments with high leverage, helping teams develop best practices,
- Set up a modern data stack with Snowflake/BigQuery, dbt, Airflow, CircleCI, GreatExpectations, Fivetran/Stitch,
- perform targeted business analyses,
- mentor and develop technical team members,
- build CI/CD workflows for application and data environments

💡Prior to freelancing, I was first engineer then data hire at 2 US based health tech companies. I was with the first company through an acquisition by Amazon and with the second team through Series B while growing the data team to 7 people.

Comfortable working in English.
