IT services
Tell us the outcome. We choose the stack from the brief, then design, build and look after the product with one UK IT team.
How we work
Web, mobile and commerce from one team
SJ Technologies provides custom IT services for startups, SMEs and enterprises. Build covers mobile, web, cross-platform and CMS work. Commerce covers catalogues, Magento, Shopify and WordPress. Engineering, AI, cloud and marketing sit around the product, not as a separate pitch.
You engage us to deliver a project: a named IT lead, designers, developers and QA, against a written scope. Source and environments remain yours.
What you can hold us to
The stack is a decision in the brief, not a package we sell first. Native, one codebase or a CMS, only where that is the honest trade-off. Checkout, payments and warehouse links in the same commerce job. Support after launch, if you want that retained.
Catalogues, checkout, payments and the platforms that have to last.
Custom products, APIs, DevOps and QA in one UK IT team.
AI, cloud and marketing where they earn their keep.
