What we build

Most projects mix a few of these. We take them from the first sketch to support after launch.

Shopify

Store setup
Themes, products, payments and shipping, ready to sell.
Move to Shopify
Products, customers and orders from your old platform.
Shopify apps
Custom apps for one store, or public apps. We run our own.

Web and mobile

Websites
Fast, search-friendly sites that bring in enquiries.
Web apps
Booking systems, admin panels and customer portals.
Mobile apps
iOS and Android from one codebase.

Systems and AI

Backend
Databases, payments, background jobs and APIs.
AI features
Search, writing and support tools built on Claude.
Automation
Workflows that take repetitive work off your team.

We work with Shopify, React, Next.js, React Native, Node.js, TypeScript, Supabase, PostgreSQL, MongoDB, Redis and the Claude API.

How a project runs

  1. Discover

    How your business works today, and what a good result looks like.

  2. Design

    Screens you can click through before anything is built.

  3. Build

    Working versions shared as we go, so you can steer early.

  4. Launch

    Tested on real phones and browsers, then released carefully.

  5. Support

    Fixes, updates and new features after launch.

SingleTec is a small software studio. Since 2023 we have run our own Shopify app, SGT, which carries the Built for Shopify badge. Running a product every day keeps us careful with client work: fast pages, reliable systems, and someone who answers when something needs fixing.
