Placing Shopify + AI developers, see open talent

Hire Firebase developers who treat security rules as seriously as the schema.

Auth, Firestore, Cloud Functions, and push, built by engineers who know Firebase's real tradeoffs, a Firestore document shape that saves you money or quietly costs you thousands, security rules that either mean it or don't, functions that either account for cold starts or don't.

Why hire through Code Elevator
Security rules written like code. Rules are drafted, tested against the Emulator Suite, and reviewed, not left at a permissive default because the deadline was close.
Cost-aware data modeling. Document structure and denormalization decided around your actual read/write volume, because Firestore's pricing punishes the wrong schema fast.
No cold-start surprises. Cloud Functions architected with cold-start latency as a known constraint from day one, not diagnosed after a user complains an action feels slow.
Typical rate

from $22/hr

A typical range. Your final rate depends on experience level, timezone overlap and how long you book for.

Questions

Answered before you ask.

When you need auth, a database, and push working fast without standing up infrastructure, early-stage apps, MVPs, and products where iteration speed matters more than fine-grained infra control. We'll say plainly when your scale or requirements have outgrown it.

Mainly through document design, denormalizing to cut unnecessary reads, batching writes, and setting budget alerts before launch, not after the first surprise invoice arrives.

Against the Firebase Emulator Suite with a real test suite covering both the access that should succeed and the access that should be denied, rules that have never been tested against a denial case aren't really tested.

Yes. Though it takes planning. We design data models and Cloud Functions with that possibility in mind where it matters to you, rather than assuming you're locked in forever.

What you're not risking

Every way out of this hire is already written down.

Two-week replacement

Not a fit? Replace anyone in the first two weeks. No questions asked, no replacement fee. We re-match from the same vetted pool.

No placement fee

You pay only for engineers who actually start. Seeing candidates costs nothing.

No lock-in

Dedicated and managed engagements run on a monthly rolling contract. Cancel with notice.

Rate agreed up front

You see the number before you commit. Nothing is added on top of it later.
