What's the latest side project that you completed?

I have been building something or the other since I was in college. Miniature robots, ecom stores, app prototypes, and what not The latest and one of the most interesting side-project I built was this: While traveling to a remote and cold village-like place in the mountains, I met a small-cafe owner couple. Due to low connectivity and budget, but high tourism, they were struggling to keep a track of customers, their orders, and payments. They wanted a simple, no-cost, low-tech 'Sales record keeping mechanism'. So I opened Google sheets. xD I gave them a link in which all they had to do was add the customer's name, select the item ordered from a drop down, and later update the payment status. That's it. I also added custom features and analytics like revenue stats, best sellers, etc all on Google sheets. They loved it! And I accepted payment with a week's worth of free hot chocolate. 😌
