Hey there! I’m your friendly neighborhood code-slinger with 10+ years of experience making the web a cooler place—one pixel (and punchline) at a time. What I Actually Do (Besides Consuming Alarming Amounts of Coffee ☕): 🖥️ React & Next.js I build high-performance, ultra-smooth web apps that load faster than your morning coffee kicks in. Need a site that’s beautiful, responsive, and makes your competition jealous? I’m your dev! 🤖 AI & Machine Learning Why settle for a basic website when you can have one that’s smart? I sprinkle in chatbots, recommendations, and intelligent automation so your site works harder—while you relax. 🛒 CMS & E-Commerce WordPress, Shopify, Wix, WooCommerce—if it has a dashboard, I’ve customized it, optimized it, and probably fixed it after someone else broke it. Payment gateways? Product pages? Cart that doesn’t randomly explode? I’ve got you. 🎬 Digital Marketing & Video SEO, ad campaigns, and video production (voiceovers included—think Morgan Freeman, but with more dad jokes). I make your brand look and sound awesome across the web. 🕴️ Business & Team Stuff I’ve recruited tech talent at AWS and Google, survived meetings at Paychex, and now run OooWee Business Solutions—where we make digital magic and actually meet deadlines. 🧰 Tech Toolbox Frontend: React ⚛️, Next.js 🚀, JavaScript, TypeScript, HTML, CSS, Tailwind Backend: Python 🐍, Node.js, REST APIs, AI/ML (TensorFlow, scikit-learn, etc.) CMS: WordPress, Shopify, Wix, WooCommerce Cloud: AWS ☁️, Google Cloud Other: Salesforce, Microsoft 365, Video Editing, CRM systems, and a suspicious number of browser tabsNumpy
