What I'm building now, and a few things I built before.

Nusii

Online proposal software, since 2013

The Nusii homepage: “The proposal software serious businesses use to win more work.”

Nusii is online proposal software for agencies, consultants and other service businesses. You put together a good-looking proposal from a template in minutes, send it as a link, see when your client opens it, and get it signed and paid online.

I co-founded Nusii with Nathan Powell in 2013. It's self-funded and profitable, with no outside investors, and run from Madrid.

Chess coordinates, made into games

The e4e5Nf3 homepage: “Know every square by name.” next to a board where the queen takes f7 for checkmate, with Qxf7# typed below it.

e4e5Nf3 turns the chessboard's coordinates into quick games. You name squares, find them, call their colour, spot mates and drill your openings, until you know every square by name.

There's one rule: you never click or drag a piece. Every move is typed the way it's written on a scoresheet, like Nf3, Qxf7# or 0-0. Never learned how? The first game teaches you.

You can play as a guest, or sign in with just your email to earn XP, keep a daily streak and build a map of which squares you know cold and which still need work.

Six games

Learn the Notation
Nine short lessons, from square names to reading a whole game.
Name the Square
A square lights up and you type its name.
Find the Square
A coordinate appears and you click it on a board without labels.
Light or Dark?
Say whether a square is light or dark, without looking at a board.
Mate in One
Find the checkmate and write it down.
Openings
Play your side of an opening from memory while the game plays the other.
Name the Square: g8 is lit up on an empty board and a “g” has been typed, with a streak of 7 and a score of 150.
Name the Square
Find the Square: the game asks to find f8 on an empty board without coordinates.
Find the Square
Mate in One: Ne5 is typed and played, and the game answers “Checkmate! Légal's mate.”
Mate in One
Openings: the Ponziani Opening, Jaenisch Variation, after 1. e4 e5 2. Nf3 Nc6 3. c3 Nf6, with a blue arrow showing the next move, d4.
Openings
Lesson 5, Check and checkmate: Bb5+ is taken apart into B for bishop, b5 for the square and + for check.
Learn the Notation takes every move apart, symbol by symbol
