Your AI integrations aren't working. Your automation is fragile. Your codebase makes new devs quit. I fix that usually in weeks, not months. 𝗪𝗵𝗮𝘁 𝗜 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗱𝗲𝗹𝗶𝘃𝗲𝗿: - APIs that scale: handled 50K+ daily requests without breaking - Automation that sticks: saved teams 15-20 hours weekly with n8n workflows - Code another developer can extend without breaking everything - AI systems that work (not just "integrated"): reduced manual work 60-70% for clients, built AI reception systems handling inbound calls and routing 𝗪𝗵𝘆 𝗜'𝗺 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁: I don't just write code. I take ownership of the problem. LLM integration failing? I diagnose it. Data pipeline bottlenecked? I optimize it. Security holes in your Firestore rules? I close them before they cost you. Codebase a mess? I refactor it to be maintainable, not just working.
