Projects

Automatic roulette player
Golang
This was a sample project for a client. It is an automated player for roulette in online cassinos that reads the drawn number and automatically selects the next numbers by moving the cursor and clicking, following the player's "strategy". It uses number recognition and library to interface with the operating system.
End War
Solidity
This is a game to try out Solidity capabilities and the Ethereum blockchain. It is deployed to the Sepolia testnet (read more below) and implements the Proxy Upgrade pattern to allow for upgrades. The game simulates a world where wars can be requested by players - to end with the people's peace. Players can spend resources (ETH or other EVM compatible token) to start a war (triggerWar) and invest in the power of a territory (invest). The game ends if all people die or are part of the same nation, in which case there won't be anything else to do.
