Full-Stack Engineer - AI Chatbots - Web Apps - APIs - 5 Years Exp

Portfolio available on request. If you have an upcoming web or AI project, save yourself the trouble of sorting through unqualified profiles let's connect and I'll give you an honest opinion on how to make it a success. I'm a Full-Stack Engineer with 5+ years building complex systems for real businesses: AI chatbots with memory and integrations, SaaS dashboards with role-based access, sales and e-commerce systems, REST APIs, and workflow automation. Things I'm especially good at: - AI Chatbots and Virtual Agents context-aware bots integrated with OpenAI, n8n, webhooks, and business tools. Not toy demos production systems that handle real conversations and connect to your existing stack. - Web Applications and Dashboards — full-stack apps with React/Next.js frontends, Node.js or Python backends, and proper databases. Admin panels, internal tools, SaaS products. - Sales and E-commerce Systems — payment integrations (Stripe, MercadoPago), checkout flows, inventory management, and CRM-ready backends. - APIs and Automation REST APIs, n8n workflows, third-party integrations, and process automation that saves real time and money. - Fixing broken projects if another developer left things unfinished or messy, I come in, review the codebase, and get it done right. My rate is competitive and my work is clean. I don't disappear mid-project or ghost on deadlines. I communicate clearly and treat your project like it's my own business. If you want to talk through your project, send me a message I'm happy to hop on a quick call before you commit to anything.
