Job Success
Opelousas, United States - 4:01 pm local time
I build trading bots and automation systems that execute your strategy 24/7 on crypto, forex, DeFi, and prediction markets, the way you designed it, without interference. Across 30+ projects and counting, the systems I've built have generated over $250,000+ in tracked profit for live accounts.
Here's what most developers won't tell you: a perfectly written bot built on a flawed strategy will still lose money. Before I write a single line of code, I review your strategy logic entry rules, risk parameters, execution assumptions because catching a problem there saves you weeks and real capital. Most developers jump straight to coding. I don't.
I also build for live market conditions, not just ideal ones. That means slippage modelling, latency handling, proper position sizing, and failsafes so your bot doesn't just pass a test, it survives real trading.
What I deliver for clients:
Crypto trading bots on Binance, Bybit, Coinbase, and Alpaca with AI/ML signal generation, real-time execution, and Telegram alert integration. Solana MEV bots, arbitrage systems, sniper bots, flashloan bots, and DeFi automation on Jupiter, Raydium, and Orca. MT4 and MT5 Expert Advisors for forex scalping, swing, grid, and prop firm challenge systems built for FTMO and MyForexFunds with full drawdown protection. Prediction market automation on Polymarket and Kalshi. Copy trading systems, wallet trackers, and market-making bots. Smart contract integrations and full deployment on AWS or VPS production-ready, not just delivered and forgotten.
Clients come back and they refer others because the systems actually work in production. I don't disappear after delivery. Every project includes source code, documentation, and a handover so you understand exactly what's running on your account. For ongoing systems, I stay available for monitoring, updates, and scaling.
If you have a strategy you want automated, a system that isn't performing the way it should, or an idea you want to turn into a working bot message me with what you're building. I'll tell you exactly how I'd approach it, what's realistic, and what it'll take to get it live.
Let's build something that runs while you sleep.
