We built a Next.js finance tool that syncs ledger entries and loads pages in 80ms using React Server Components.
load in 80ms using server components.
Actions execute database mutations with zero API fetch latency.
System Bottlenecks
Most budgeting apps are slow mobile portals that take seconds to load. Standard spreadsheets lack access control, session authentication, and automated data charts.
Architectural Move
We built Fintraq on Next.js. The app runs on Neon serverless PostgreSQL, using Drizzle ORM for schema safety, Upstash Redis to cache dashboards, and Next.js Server Actions to write updates directly to the database without API fetch loops.
Execution Path
Schema Design: We created ledger tables with check constraints in PostgreSQL using Drizzle ORM.
Session Auth: We set up Better Auth to handle user logins and route access permissions.
Dashboard Compilation: We built charts using Recharts in server-rendered components to minimize JavaScript bundle sizes.
"The dashboard loads instantly. Transactions sync without the database lag typical of standard SaaS budget trackers."

Core Stack
- Next.js (Turbopack compiler)
- Neon PostgreSQL & Drizzle ORM
- Better Auth (Secure session control)
- Tailwind CSS v4 & Motion
Under-the-hood Challenge
Maintaining low page latency while querying thousands of transaction rows. We solved this by caching computed transaction aggregates in Upstash Redis, updating the cache only when a Server Action modifies the database.
Fintraq is built around fast page loads. By shifting data fetch logic to React Server Components and caching query results at the edge, the app runs without database connection bottlenecks.
