Summary
🤩
Rockstar🎓
Top SchoolMike Alfare is a senior data engineer with 10+ years of experience designing and building enterprise data platforms, currently shaping Kaleo and Carrum Health’s data stacks using S3, Redshift, Airflow, Athena and Tableau. He began in actuarial analytics, which gave him a rare combination of business judgment and technical rigor—able to spot where data appears correct but operational reality differs—and progressed through BI, data science, product management and hands-on engineering. At Markel he built the enterprise data lake, led DevOps/cloud practices and launched production data science workflows; at dbt Labs he contributed to core OSS projects and helped integrate materialized view and Iceberg support across adapters. He blends product sensibility with deep execution: owning migrations, re-architecting test frameworks to cut run times in half, and mentoring engineers while co-leading multiple Python user groups. Outside of corporate roles he ran a successful tutoring business, a background that informs his approachable mentorship and capacity to teach technical topics to broad audiences.
