Taarly V2 — Digital Card + Link-in-Bio

Focused PERN rebuild: Next.js web, Expo mobile and Express + PostgreSQL backend. Digital card / public profile at /api/u/:username (no auth), ordered toggleable links, three email-signature templates (Classic/Modern/Minimal) with ready-to-paste HTML, CRUD contacts/tags/notes, follow-ups with snooze/complete + weekly/monthly/quarterly/yearly recurring cadences, avatar upload to /uploads, JWT via httpOnly cookie (web) or Bearer (mobile) reloaded from DB each request. Postgres on 5433, backend on 4000 — zero AI at runtime, just predictable PERN.

We partnered with the team to scope the smallest meaningful slice, then iterated weekly with demos to keep stakeholders close to the work. The architecture prioritises observability and a calm on-call experience over premature flexibility.

Today the system serves real users in production, with a deploy cadence that lets the team ship safely without ceremony.
