Shopify Developer Los Angeles — Senior LA Shopify Agency

Shopify development for LA DTC brands, multi-store retailers, and post-launch stores that have outgrown their theme. Senior Shopify engineers — Liquid, Hydrogen, custom apps, checkout extensions — built to sell, not just to exist.

The problem most LA Shopify stores have

Your theme was fine on day one. Now it’s a patchwork of 27 apps, conflicting CSS, a slow cart, a checkout you can’t customise, and a dev who ghosted. Every new request (“add a size guide”, “build a subscription flow”) takes two weeks and breaks something. That’s not a theme problem — that’s an engineering problem. We fix it.

What we build in Shopify

• Custom themes (OS 2.0) — sections everywhere, JSON templates, metaobjects, built for your brand, not a $200 marketplace theme.
• Hydrogen / headless storefronts — Shopify backend + Next.js or Remix frontend for Shopify Plus brands that need Lighthouse 95+ on mobile.
• Checkout extensions & Functions — line-item customisations, shipping & payment logic, upsells, real checkout A/B tests (Shopify Plus).
• Custom Shopify apps — private/public apps in Remix or Rails, for inventory sync, ERP integration, wholesale portals.
• App consolidation & speed rescue — audit your 20+ apps, keep the 5 that earn money, strip the rest, rebuild the 3 you actually need.
• Migrations — WooCommerce, Magento 2, BigCommerce, or Shopify-to-Shopify Plus.

Why LA brands pick us over a Fiverr Shopify dev

• Senior only. The developer on your Slack is the one writing the Liquid — no offshore handoff.
• LA timezone, LA context. Same hours, same market, same understanding of your customer.
• Conversion bias. We don’t just ship pixels — we ship revenue. Every sprint has a CVR or AOV target.
• Ownership clarity. Your code lives in your GitHub, your Shopify, your domain. We build to hand off cleanly on day one if needed.

How we work

1. Week 1 — Audit + scoping. Lighthouse, app list, checkout review, CVR benchmark. You get a written scope with fixed milestones and a CVR / AOV target per sprint.
2. Weeks 2–6 — Build in 2-week sprints. Demo every Friday in your Shopify preview theme. You approve before anything ships to live.
3. Launch + 30-day post-launch support — GA4 validation, speed watch, CVR tracking, bug triage.

Who we work with in LA

DTC brands doing $1M+/yr in GMV, multi-store retailers, Shopify Plus merchants who need a custom checkout, and LA startups launching a subscription product. If you’re pre-launch and need a $500 theme install, we will refer you to a partner — we’re not the cheapest option, we’re the one you call after the cheap option didn’t work.
