Most businesses don't need another developer. They need someone who can connect systems, automate processes, and build the missing pieces between them. That's what I do. My background is in Full Stack development and payment systems, where I've spent years building products, integrations, and business-critical workflows. More recently, I've been focused on automation and AI-powered systems that eliminate repetitive work and connect the tools businesses rely on every day. What makes me different from many automation specialists is that I'm not limited to no-code tools. When an automation platform reaches its limits, I can build the custom APIs, backend services, dashboards, and integrations required to make the entire system work reliably. Automation & Integrations n8n | Make | Zapier | AI Workflows | OpenAI Integrations | Webhooks | REST APIs | Business Process Automation Stripe Stripe Connect | Subscription Platforms | Marketplace Payments | Payment Flows | Webhooks | Billing Systems | Checkout & Customer Portals | Revenue Operations Automation Full Stack Development React | Next.js | Node.js | TypeScript | SQL | PostgreSQL | MongoDB | Backend APIs AI Powered Enterprise Solutions | AI Workflow Automation | Fintech Solutions | CRM | MVP | Mobile Application Development | Web Development Projects I Typically Help With - Lead management and CRM automation - AI-powered business workflows - Internal operations systems - Stripe billing and subscription platforms - Custom integrations between multiple SaaS tools - Workflow automation with custom backend logic - Customer onboarding systems - Marketplace and payment infrastructure - Reporting and operational dashboards One thing I've learned from building software is that automation is rarely about the automation itself. The real challenge is designing systems that are reliable, scalable, and easy for teams to operate. That's why I approach every project from a systems perspective first, then choose the right combination of automation tools, APIs, and custom development to solve the problem. If you're looking for someone who understands both automation platforms and the engineering behind them, I'd be happy to discuss your project.
