About

I'm Miles Delgado, a data engineer based in London.

I've spent the last 10 years building pipelines, warehouses and the dashboards people actually trust, most recently on a small team where I look after data quality checks and incremental models. Before that I bounced between agencies, startups and one very large company.

I started Small Thread in 2025 as a place to think out loud. Most posts begin as notes from real projects: something broke, I fixed it, and I wanted to remember why. If one of them saves you an afternoon, it was worth writing.

What I write about

• Data contracts
• Slowly changing dimensions
• Data quality checks
• Incremental models
• Backfills
