BEHIND THE PATCH

About me & this site

Databases, code, and the habit of keeping notes.

Hello, I’m DB PATCH.

I work in database operations and backend development, mainly with PostgreSQL. I also explore where AI can help in engineering practice.

This site holds the problems I encounter, the approaches I try, and ideas worth testing. I want to keep the context and reasoning, not just the conclusion.

DB PATCH.

PostgreSQL & database operations

Queries, backups, recovery, and replication. Reliable systems and verifiable operations.

Backend engineering

From APIs to storage: performance, boundaries, and engineering trade-offs.

Practical AI

Trying tools, checking outputs, and distinguishing tested results from unconfirmed assumptions.
