What big companies should build when coding is no longer scarce

A practical framework for developer portals, automatic migrations, and platform teams in large engineering organizations.

Summary

When code generation becomes abundant, engineering leverage moves to systems that reduce coordination cost: golden paths, service catalogs, automated migrations, ownership maps, and reliable guardrails.

1. Developer portals should answer operational questions

The useful portal is not a bookshelf of documentation. It is the place where teams see their services, owners, standards, dependencies, health, and next required actions.

2. Automatic migrations are the scalable adoption mechanism

Manual migration campaigns fail because every team has different incentives. The platform should create PRs, run codemods, track completion, and make exceptions explicit.

3. AI agents need platform constraints

Agents become more useful when the environment tells them what “good” means: approved libraries, deployment paths, service templates, test expectations, and review policies.
