What you get

We are based at 432 2nd Ave, reply within 24 hours, and build for New York companies as well as brands across the US and Canada.
Shopify and Shopify Plus
We build, migrate, and improve Shopify stores without pretending the platform has no limits. That includes theme work, checkout settings, apps, redirects, payments, and product data.
WooCommerce builds
If WooCommerce fits your stack, we build stores on WordPress with practical admin flows, product data, payment setup, and SEO basics handled from the start.
Custom web apps
We build React, Next.js, Node.js, Laravel, and PHP applications for internal tools, customer portals, and marketing sites. You get code that another competent team can read later.
SaaS development
We help define the core workflows, user roles, billing touchpoints, admin screens, and APIs your SaaS needs. Then we build the product in phases you can review.
Speed, SEO, and schema
We fix technical issues that slow pages down or make content hard for search engines to parse. Work can include Core Web Vitals, redirects, clean sitemaps, and Product, Offer, or Review schema.
AI feature development
We add generative AI features where they have a clear job, such as content drafts, support helpers, search assistance, or back-office automation. We avoid AI for its own sake.
How it works
From first call to launch
01
Scope the work
We review your current site or idea, business goals, users, constraints, and what has to be true for the project to be worth doing.
02
Map the build
You get a practical plan for pages, data, integrations, risks, and the first release shape before development starts.
03
Build and review
We work in visible chunks, show progress, and make decisions with the tradeoffs stated clearly.
04
Launch and improve
After release, we watch for bugs, speed issues, SEO problems, and conversion friction so the build can keep improving.
