An established product does not always need a new backend to improve its interface. Curiosive's published portfolio records Lizzt in the Netherlands: a Next.js frontend rebuild that kept the existing Supabase backend and brought event planning, participant workflows and guided AI into one interface.
We work remotely from Ankara, Türkiye. For Dutch teams with an existing application, the first scope should identify what already works, which workflows need change and how a release will be checked. Lizzt is a delivered project example, not evidence of a local office or a guaranteed outcome for another product.
Lizzt's published scope retained Supabase while rebuilding the frontend in Next.js, TypeScript and Tailwind CSS. The product covers event tasks, costs, chat, files and participant actions. For a similar change, map current API and database contracts before implementation, and identify the workflows whose behavior must remain intact during the transition.
Start with the actions each role can perform and the data each participant may read. Supabase documents Postgres row level security as a database authorization mechanism, with grants and policies that need their own tests. This is guidance for scoping a new or existing Supabase project; it is not a claim that a particular policy has been audited in Lizzt.
The Lizzt case describes a multilingual interface including Dutch and English. A release plan should cover authentication, longer labels, event permissions, empty states and the guided AI flow in each supported language. Select a complete user task for the first increment, then review its behavior before expanding the rebuild.
Senior engineers building your product with AI coding agents: web, mobile, SaaS or browser extension, reviewed before anything ships.
AI-accelerated development, billed monthly. We confirm scope, capacity and start date in writing before checkout.
No. Inspect the existing backend and identify the change required by the user workflow. A frontend improvement does not by itself justify a database migration.
Multilingual interface work is part of the published Lizzt scope. The languages, content ownership and acceptance checks for your product must be agreed separately.
Curiosive is run from Ankara, Türkiye and works remotely. The Netherlands is the country recorded for Lizzt in the published portfolio.
