We turn ideas into working software, from A to Z.

// Example: a simple Flutter screen
import 'package:flutter/material.dart';

class WelcomeScreen extends StatelessWidget {
  const WelcomeScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Welcome')),
      body: Center(
        child: FilledButton(
          onPressed: () => Navigator.pushNamed(context, '/start'),
          child: const Text('Get started'),
        ),
      ),
    );
  }
}

// Example: a Firebase callable function
import { onCall, HttpsError } from 'firebase-functions/v2/https';

export const saveNote = onCall(async (request) => {
  if (!request.auth) {
    throw new HttpsError('unauthenticated', 'Please sign in first.');
  }
  const text = String(request.data?.text ?? '').trim();
  if (!text) {
    throw new HttpsError('invalid-argument', 'The note is empty.');
  }
  // Save the note for request.auth.uid ...
  return { saved: true };
});

# Example: count orders by status in a CSV export
import csv
from collections import Counter
from pathlib import Path

def count_by_status(path: Path) -> Counter:
    with path.open(newline="", encoding="utf-8") as f:
        return Counter(row["status"] for row in csv.DictReader(f))

if __name__ == "__main__":
    for status, total in count_by_status(Path("orders.csv")).items():
        print(f"{status}: {total}")
