My Stack

Leonard Weise

Here's where I'm currently most productive:

1. DB

I've found serverless Postgres for general and Mysql for heavy duty lifting, and libsql for near-edge hosting, to be incredibly powerful.

2. ORM

For TypeScript, I've found Drizzle ORM the best to work with in fast iteration cycles

Primary: Drizzle
import { pgTable, serial, timestamp, numeric } from 'drizzle-orm/pg-core'

export const metrics = pgTable('metrics', {
	id: serial('id').primaryKey(),
	timestamp: timestamp('timestamp').notNull(),
	value: numeric('value', { precision: 18, scale: 8 }).notNull(),
	volatility: numeric('volatility', { precision: 10, scale: 4 }),
	volume: numeric('volume', { precision: 16, scale: 2 }),
})

3. Rendering

Primary: React Server Components

I use React Server Components extensively, enhanced with tRPC for end-to-end type safety:

// Financial data fetching with tRPC
export default async function Dashboard() {
  const data = await api.metrics.getDaily.query({
    metrics: ['volatility', 'volume'],
    timeframe: '24h'
  });

  return (
    <DataGrid
      metrics={data}
      components={{
        VolumeChart: () => <VolumeAnalysis data={data.volume} />,
        VolatilitySeries: () => <VolatilityIndicator data={data.volatility} />
      }}
    />
  );
}
