Own product / Immigration
An application for immigration law firms that manages each regularised client's renewal window, sends alerts by WhatsApp or email and collects documents through a multilingual portal.

The extraordinary regularisation leaves each firm with dozens or hundreds of permits expiring on different dates. Each renewal has its own window: it opens before expiry, there is a grace period afterwards and, once that has passed, the client risks penalty proceedings. Tracking it in a spreadsheet works until someone misses a date.
02 / Solution
Renuva is a multi-firm application on Next.js and Supabase, hosted in the European Union. The firm imports its client list from CSV or Excel, the system validates each NIE and works out the renewal window status for each case. Alerts go out through the official WhatsApp API when there is consent and an approved template, and by email otherwise. Clients upload their documents to a portal in Spanish, Arabic or French.
The expiry date is supplied by the firm, with its source recorded
The window is calculated the same way in the database and in the application
First alert from 75 days before and a weekly reminder, at most one a day
The portal opens with a single-use link and a code or the date of birth
A case is marked ready when the professional accepts all required documents
Isolation does not depend on the application filtering correctly. Composite keys and a trigger prevent data from being mixed or moved between firms.
NIE and passport numbers are encrypted per field, and special category documents are hidden from the assistant role.
Each firm connects its own number through Meta's embedded signup. Without consent or a signed data processing agreement, no data goes to Meta or to the email provider.
03 / Scope
04 / Impact
The firm sees on a dashboard which renewals are open, which are in the grace period and which are out of time, and no longer chases each client by hand. Renuva is currently in a pilot phase: the document lists for each route need review by a lawyer and the Arabic and French translations are provisional before it opens to real firms.
05 / Questions
No. The firm supplies the date from the decision or the TIE, and the system records where it came from. Renuva calculates the renewal window from that date, which is where things get forgotten.
No. Renuva does not send data to any language model. The deadline and alert rules are written and tested.
