WHAT THEY DO

What does a senior full-stack developer work on?

01

Ship whole features.

Schema, API, screens and deploy, owned by one person, so nothing waits on a hand-off.

02

Add login, roles and permissions.

Each user type sees what it should, checked on the server as well as in the UI.

03

Wire up billing.

Stripe subscriptions and payments, with retry logic for failed cards and records that match your database.

04

Connect the tools you run on.

CRMs, booking systems and email providers, integrated with logs you can read when something fails.

05

Keep deploys boring.

CI/CD on your cloud, so releasing is a merge and anyone on the team can do it.

06

Pick up after the MVP.

The engineer stays in your Slack after launch and keeps the backlog moving.

HOW AI MAKES THIS ROLE FASTER

One engineer covers the whole stack with AI. A second senior signs off.

Full-stack work has a lot of glue: types that mirror the schema, endpoints that mirror the types, forms that mirror the endpoints. AI writes most of that glue. Your engineer spends their time on the decisions, and a second senior engineer reviews every line before merge.

StepWhat AI doesWhat the engineers checkThe gate it passes
Schema to APIDrafts the migration, the endpoint and its validation from the specThe data model holds up for next quarter's features as wellSenior review on every merge
API to screenDrafts typed client calls and the form or tableLoading, error and permission states all handledSenior review on every merge
TestsDrafts unit tests and an end-to-end test for the new flowThe tests cover the money path and the permission edgesSenior review on every merge

Across 470 open-source pull requests, CodeRabbit found AI-co-authored code carried ~1.7× more major issues and ~2.7× more security defects. One person writing the whole stack is exactly where a second reviewer earns their keep. Client code is never used to train models.
