Company

Company profile

A UK IT agency for custom web applications, mobile apps and software. Named people, a written scope, and source that remains yours.

About the agency

What SJ Technologies does

SJ Technologies designs and builds custom web applications, iOS and Android apps, and software systems for startups, SMEs and enterprises. We work in the UK and with clients abroad.

You hire us to deliver a product: a named lead, designers, developers and QA, against a written scope. The stack is chosen from the brief, not from a favourite framework.

Ecommerce, Magento, WordPress, Shopify, QA, application maintenance and IT consulting sit with the same team. We do not hand the job to a chain of subcontractors you never meet.

Web, mobile, software

The three kinds of product we take on as one team

Named people

An account owner and an engineering lead you can meet

Your source

Code, environments and access remain yours under the contract

What we build

Tell us the outcome. We choose the platforms from the requirement, then design, build, test and look after the product.

Mobile development

Native, cross-platform or PWA. UX, engineering and store or web release in one team.

Web development

Customer sites, staff portals and front-office apps. Stack chosen to last.

Software systems

Custom products, integrations and internal tools with a written scope.

Ecommerce

Catalogues, checkout, payments and the warehouse links that make an order leave.

QA and support

Tests against the brief, then maintenance after launch if you want that retained.

IT consulting

Advice before you commit budget: what to build, what to leave, and in which order.

How we engage

A project, not a black box

The engagement is a written job. Platforms, integrations and what is out of the brief are named before build starts. Changes go through the same writing.

Sectors we already know

Healthcare, retail, logistics, finance and the other industries on this site. The brief still decides the product; the sector knowledge shortens it.
