What I built from scratch: systems, sites and tools. What each one solves, who for, and what it was built with.

Pickly
A shopper with nobody home to take a delivery sends the parcel to a partner shop instead. The shop registers it on arrival, notifies the shopper and hands it over at the counter. The pickup is a payment event: it sums the fees, records whether it was paid by PIX, cash or card, and prints the receipt. Each shop is an isolated tenant with its own subscription.

Elysium
Site for a private Cabal server: sign-up with e-mail confirmation, profiles, a ranking that updates live on screen, news, downloads and payment. Dark theme, with the public side built to turn a visitor into a sign-up.

MaxCraft
The page for MaxCraft, a private Minecraft server built around PvP. It introduces the server, the modes and the events, and puts the join address in a copy button on the first screen. The visitor leaves the page already inside the game.

WaterBill
One water bill arriving for two: a house and a set of apartments. The utility's meter reads the whole property and an internal meter reads one of the two sides. The tool splits the bill, halving the fixed charge and sharing the variable charge by consumption, and lands on the printed cent. It runs in the browser with no backend, and each month stays on the machine.

GrainHub
System that controls a drying operation from the moment the grain arrives to the close of the harvest. It holds customers, partners, dryers, batches, stock, movements and load control in one place, with PDF reports and screens that follow the operation live.

The next on this list could be yours. Tell me what you need and I will tell you how I would build it, what it costs and how long it takes.
