Legal Platform App

We are looking for an experienced full-stack developer to build a bespoke multi-portal web and mobile application for a paralegal and clerking consultancy. The application serves three separate user groups through three distinct authenticated environments: a public-facing portal, a client portal for law firms and barristers' chambers, and an internal staff portal. Each portal has its own access controls, navigation, and content, enforced at both route and API level. The core features include a two-track consultant application journey with UKVI identity verification integration, an adaptive instruction submission form that changes based on client type, separate consultant profile systems for paralegals and law firms and for clerks and barristers, a matter-linked clock-in and out system, a staff HR register, a retainer opportunities board, and a headless CMS-managed blog with a subscription gate. The application must be delivered as a web application and as native iOS and Android mobile applications. We have a full written technical specification ready to share. We are looking for a developer or studio with demonstrable experience building multi-role authenticated platforms with mobile delivery. Please include examples of comparable work in your application. Budget and timeline are to be proposed by the applicant based on the specification provided.
