Donny Nguyen

Hey, I'm Donny 👋 Blockchain developer and automation specialist based in Texas. I've spent the last few years deep in the trenches of Web3 - building trading bots, DeFi protocols, and crypto payment systems that actually work in production. My Background I got into development through crypto. Started by building arbitrage bots to trade tokens across different chains, learned the hard way what works and what doesn't when real money is on the line. That experience taught me to build systems that are reliable, efficient, and handle edge cases gracefully. Now I split my time between:

Building Shopify apps for e-commerce merchants Creating automation tools for lead generation and outreach Taking on freelance blockchain development contracts Running my own automated trading systems

What I Build Automation & Scraping I create tools that find information and take action automatically. Lead scrapers, email finders, data enrichment pipelines - if it can be automated, I've probably built something like it. Blockchain & Web3 Smart contracts, multi-chain integrations, DeFi protocols, crypto payment gateways. I work across Ethereum, BSC, Polygon, Base, and Bitcoin. My code handles real transactions with real money. E-commerce Solutions Shopify apps and integrations that solve actual merchant problems. Currently building CryptoCheckout Pro - a self-custody crypto payment solution for online stores. My Approach I build tools I actually use myself. Every Actor and automation I publish started as a solution to my own problem. If I needed it, chances are you do too. I prefer async communication, clean code, and systems that run without babysitting. No unnecessary complexity - just tools that work. Work With Me I take on select freelance projects in these areas:

Crypto payment integrations DeFi trading bots and automation Web scraping and lead generation systems Shopify app development Smart contract development and auditing
