About Casatrick - Blockchain Fullstack Developer
I'm Casatrick, a blockchain fullstack developer specializing in Polymarket trading bots and Web3 casino games. I ship production systems on Polygon for prediction market automation and on Solana / EVM for provably fair on-chain casino game engines.
My Polymarket trading bot work covers CLOB integration on Polygon, automated and interactive trading modes, real-time market analysis, order management, position and PnL engines, and production-grade risk controls - per-market exposure limits, max slippage, daily loss caps, and kill-switch.
For Web3 casino games, I build provably fair on-chain logic for coinflip, dice, roulette, crash, lottery, and jackpot games using Chainlink VRF and verifiable on-chain randomness. Full-stack delivery includes deposits, withdrawals, staking, NFT rewards, treasury / fee logic, and operator admin tooling.
