Pillar 02
Web and mobile apps, SaaS products, portals, internal tools, APIs and e-commerce, plus careful modernisation of software you already rely on.
Custom Software & Digital Products is the Directrix Technologies practice for building and modernising web, mobile and SaaS applications. It covers product discovery, custom web applications, mobile apps, SaaS platforms, customer portals, internal tools, APIs, e-commerce and legacy modernisation. Work is delivered in increments with demos, tested continuously, and handed over with documentation and the code repository in the client’s name where practicable. Directrix projects in this area include the Nusqa Android app on Google Play, SpeakMart and the Imdad-ul-Fuqaraa Trust website.
