We turn ideas into software that works.

// Query with PDO
$stmt = $db->prepare(
    'SELECT * FROM customers WHERE id = ?');
$stmt->execute([$id]);
$customer = $stmt->fetch();

// Customer service
public class CustomerService
{
    public async Task<Customer?> GetAsync(int id) =>
        await _db.Customers
            .FirstOrDefaultAsync(c => c.Id == id);
}

// Minimal API in .NET
var app = WebApplication.Create();

app.MapGet("/api/health", () =>
    Results.Ok(new { status = "ok" }));

app.Run();

-- Sales by customer
SELECT c.Name, SUM(v.Total) AS Total
FROM Sales v
JOIN Customers c ON c.Id = v.CustomerId
WHERE v.Date >= '2026-01-01'
GROUP BY c.Name
ORDER BY Total DESC;

export default function Balance({ amount }) {
  return (
    <View style={styles.card}>
      <Text>Balance: ${amount}</Text>
    </View>
  );
}

// Counter with React
import { useState } from 'react';

function Counter() {
  const [n, setN] = useState(0);
  return <button onClick={() => setN(n + 1)}>{n}</button>;
}

-- Customers table
CREATE TABLE customers (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(120) NOT NULL,
  created TIMESTAMP DEFAULT NOW()
);

// Fetch products
async function getProducts() {
  const res = await fetch('/api/products');
  return res.json();
}
