Shopify Development Company
Apps, themes, headless storefronts, and Shopify Plus builds from a team that ships production software — for merchants, agencies, and brands nationwide.
A full-service Shopify development company
SymTek covers the whole platform — from custom app development and theme work to headless Hydrogen builds, Shopify Plus, and migrations. Hire a Shopify developer who writes production code, not just Liquid tweaks: we run a live app in the Shopify ecosystem and build on the same React Server Components model as Hydrogen. Whether you run a Basic store or a high-volume Plus catalog, you get one Shopify agency accountable for the build. We work with merchants and brands across the country.
What we build on Shopify
One team across apps, themes, headless, Shopify Plus, and migrations.
Custom App Development
Private and public Shopify apps that hook into the cart, checkout, admin, and webhooks. We ship real backends and merchant dashboards — the same engineering behind our own app, SymTek Safe.
Theme & Section Development
Custom themes and reusable Online Store 2.0 sections built in Liquid, so your team can rearrange pages without a developer. Pixel-accurate to your design, fast, and merchant-editable.
Headless / Hydrogen
Headless storefronts on Shopify Hydrogen and the Storefront API. We build on Next.js and React Server Components — the same model as Hydrogen — for stores that need full front-end control.
Shopify Plus
Checkout extensibility, Shopify Functions, B2B, and scripts for high-volume Plus merchants. We build the customizations Plus unlocks and keep them upgrade-safe.
Store Migration
Migrations to Shopify from Magento, WooCommerce, BigCommerce, and legacy platforms — products, customers, orders, URLs, and SEO preserved with redirects in place.
Speed Optimization
Core Web Vitals and page-speed work: trimming apps and scripts, optimizing Liquid and images, and fixing the render path so your store loads fast and converts.
We ship production Shopify apps, not just store tweaks
SymTek Safe is our own Shopify app: crowdsourced package protection that integrates directly into the cart and checkout, with a merchant analytics dashboard on the back end. Running a live app in the Shopify ecosystem means we handle App Bridge, the billing API, webhooks, and checkout UI that most theme shops outsource. When you hire us, you get a team that has shipped and maintained real Shopify software — not just edited someone else's.
Frequently Asked Questions
What does SymTek build on Shopify?
The full stack: custom public and private apps, themes and Online Store 2.0 sections, headless Hydrogen storefronts, Shopify Plus checkout and Functions work, platform migrations, and speed optimization. If it involves Liquid, the Storefront or Admin API, or a custom app backend, we build it. Most engagements combine a few of these — a theme build with a custom app, or a migration plus a speed pass.
Do you work with agencies or offer white-label development?
Yes. We take on white-label Shopify development for agencies that need extra engineering capacity — app builds, complex Liquid, headless front ends, or Plus work — delivered under your brand. You keep the client relationship; we write the code and hit your deadlines. It's a common way agencies use a Shopify developer without hiring one full-time.
Do I need Shopify Plus, or is Basic enough?
Most stores do fine on Basic, Shopify, or Advanced — you only need Plus for checkout customization via checkout extensibility, Shopify Functions, B2B, higher API limits, or genuine high-volume throughput. We help you find where the plan actually blocks you before you upgrade, and we build to whichever plan you're on. If you outgrow Basic later, the work carries forward.
How do engagements work?
Fixed-scope projects for defined builds — an app, a theme, a migration — with a clear spec, timeline, and price. Ongoing retainers for stores that need continuous custom Shopify development, new sections, and optimization. Most projects run 3 to 12 weeks depending on custom functionality and integrations, and we scope that up front so there are no surprises.
Do you work with stores outside Houston?
Yes. SymTek is Houston-based and works with Shopify merchants, brands, and agencies nationwide. Shopify development is remote-first work — code, staging themes, and preview URLs — so location doesn't change how we build or communicate. Most of our clients are in other states.
