what we build

From landing page to platform.

Whatever the size, everything is built for production and real users, not as a prototype that has to be rewritten once traffic arrives.

02SaaS platforms
03Internal tools

eight deliverables, all of them yours

Your repo, on handover day.

Every deliverable lives in a repository you own. Illustrative layout:

how we work

One contract, then two tracks in parallel.

The architecture is agreed first. Then frontend and backend are built at the same time against it, and come together at integration. Every step ends with something you can review.

The standards we build against.

The standards and published guidance behind how we deliver this service, with every claim linked to its source.

01Security baseline

The OWASP Top 10 is the widely used reference for the most critical web application security risks, such as broken access control and injection [1].

02Accessible by default

WCAG 2.2 is the W3C standard for web accessibility, organised around content being perceivable, operable, understandable and robust [2].

KEY FACTWCAG 2.2 became a W3C Recommendation in October 2023 [2].

03Fast and indexable

Performance targets use the Core Web Vitals thresholds [3], and every public page meets Google’s technical requirements for indexing [4].
