Splitting a column on a live table with 200k rows in it, using expand/contract, with every phase rehearsed on a Neon branch first. 319,568 requests went through the app while it ran and none of them failed.

An agent changes your database and you find out later. git diff covers the migration file, not what the migration did, and nothing at all about the row it updated on the way past.

Databricks bought Neon and turned it into Lakebase, so an agent can get its own branch of production in seconds and the rows it writes land in a governed table you can query.

Denis ran the same task through ten isolated Claude Code agents at once — each with its own git worktree and its own Postgres branch — and diffed what all ten did to the database.

After two years on Supabase, I moved all my new projects to Neon and wrote down why: they are an agents-first company that ships everything to the API, they develop at very high velocity, and branching.

pastmonday.com is a real SaaS: auth, billing, uploads, and AI chat.

Neon releases features to the API before anywhere else, which makes it perfect for agentic coding: your agent can build what the dashboard doesn't have yet.

Continuing on Part 1 (setting up your developer environment) and Part 2 (defining your project to Claude Code), we are now jumping into Part 3, in which we are going to be building the landing page for our application.

Assuming you have followed part 1 of this series, you now have a beautiful, customized development environment, waiting for you to start using it.

Everyone says you can't code if you are not a developer.

Continuing on my agentic workflows exploration, I expand on my previous Supabase implementation of preview environments, and move to Neon for true branching.

I make an iOS app, but I am concerned non-iOS users might want to engage with the idea so I find a way to allow web payments with Stripe & bind them to a RevenueCat entitlement.

Notes on building a self: Purpose through escapism.

In the age of AI, those creating patterns will be rewarded with high amounts of satisfaction, while those with no soul to sign their work with, will be stuck in a no-reward purgatory of copying others

I ordered tartare, then I put it in a pan and posted photos of it on social media.
