−35% feature development time
ZapBook Design
Design system
Three component libraries became one, in Figma and Storybook. Handoff took 1.8 months, and feature development time dropped 35%.

WHAT THEY DO
What does a senior frontend developer work on?
01
Turn designs into working screens.
Figma frames become screens that match on desktop and mobile, built from your shared components.
02
Build one component library.
Buttons, forms and tables defined once and reused, so the next feature doesn't redesign them.
03
Make slow pages fast.
Smaller bundles, server rendering where it helps and images that load at the right size, measured before and after.
04
Build live, real-time screens.
Dashboards and displays that update as data changes, over WebSockets.
05
Merge dashboards that disagree.
Several role-specific dashboards folded into one, with each role seeing what it should.
06
Cover the UI with tests.
Component and end-to-end tests on the flows that make money, so releases stop breaking checkout.

HOW AI MAKES THIS ROLE FASTER
AI drafts the components. A senior engineer keeps the library clean.
AI is fastest at the repetitive parts of frontend work: the fifth variant of a form, the story for every state, the test for every breakpoint. A senior engineer reviews every line before merge, so speed doesn't turn into a pile of one-off components.
| Step | What AI does | What the engineer checks | The gate it passes |
|---|---|---|---|
| From design to code | Drafts the component from the Figma frame and its states | It reuses the existing library instead of adding a near-copy | Senior review on every merge |
| Stories & states | Writes Storybook stories for loading, empty, error and long-text states | Each state matches the design | Senior review on every merge |
| Tests | Drafts component and end-to-end tests for the flow | Tests check behaviour, not markup that changes every week | Senior review on every merge |
| Refactors | Proposes merging duplicate components and props | Nothing visible changes unless the design says so | Senior review on every merge |
| Review | Flags missing labels, unhandled errors and heavy imports | Every line before merge | Senior 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. A senior review on every merge is how we keep the speed and lose the defects. Client code is never used to train models.
WAYS TO WORK TOGETHER
Three ways to bring a frontend engineer onto your product.
Have a messy UI and no shared library yet? Start with a Design System Sprint, then keep a frontend engineer on a retainer.
Recommended
Continuous Delivery Retainer
from $3,375/month · 150 hours
150 hours a month of your frontend engineer on a backlog we agree with you, with senior review on every merge. The price depends on the role and is confirmed on a 30-minute call.
See the retainer →Prepaid Hours
$45/hour · 20-hour minimum
Buy 20 to 120 hours for scoped work, valid for 12 months. Bigger blocks cost less per hour. Need more than 120? The retainer fits better.
See hour blocks →Embedded team
lead + 1 engineer from $8,000/month
A tech lead plus your frontend engineer inside your repo, your Slack and your sprint rituals. Bigger teams are quoted to fit.

What changes when you skip the hiring search?
| Hiring your own | Working with SociiLabs | |
|---|---|---|
| Time to first contribution | A search, interviews, notice period, then onboarding | Contributing in 15 days |
| If it doesn't work out | 46% of new hires fail within 18 months (Leadership IQ) | We replace the engineer, handover time isn't billed, and you keep the code and history |
| Who reviews the code | Whoever you already have | A senior engineer, on every merge |
| How AI is used | Depends on the person | AI in the loop on every task, behind a review gate |
| Commitment | Salary, benefits, equity | Monthly retainer or a block of hours |
