SmartPockets

Most personal finance apps optimize for budgeting; few help cardholders actually manage their portfolio of credit cards — payment timing, utilization, rewards, and the cognitive load of switching between issuer dashboards.

A Plaid-synced credit-card dashboard with card management, transactions, wallet organization, settings, and an AI assistant interface for surfacing payment and account insights.

• 01

  Plaid Link + transactions sync via Convex actions, normalized into a single transactions schema

• 02

  Card-level utilization and payment-due tracking driving prioritized notifications

• 03

  AI assistant scaffolded for surfacing account-level insights from transaction history

• 04

  Turborepo monorepo with apps/app + apps/marketing, shared @repo/* packages

• 05

  Email infra via React Email + Resend; auth via Clerk

• Live and open source at smartpockets.com — an alpha / MVP, intentionally not presented as a finished product.
• Plaid Link and transaction sync normalize into a single Convex schema that drives card-level utilization and payment-due tracking.
• Built as a Turborepo monorepo (app + marketing) with Clerk auth and React Email + Resend transactional email.

Alpha / MVP portfolio project — not a finished product.

End-to-end full-stack TypeScript: financial-data integration, schema design under realtime constraints, monorepo architecture, transactional email, auth, AI feature scaffolding.

The hardest part was schema design under realtime constraints — Convex makes the optimistic UI cheap, so the work shifts to making the source-of-truth normalization predictable.
