I spent a week or two creating a trading tool for the popular video game EVE Online. The tool identifies regional arbitrage opportunities between large market hubs and allows me to prioritise the movement of goods to maximise profit while minimising time investment. It also helps me update orders efficiently.
As it provides a decent competitive advantage I have no plans to publicise it, although it is on Github as a portfolio piece.
Thanks. You too. I lost my partner of 3.5 years recently and this will be my first Christmas since it happened. I'm with family but it doesn't come anywhere close to filling the hole they left.
