Full-Stack AI Integration | n8n, LLM APIs & Custom SaaS Automation

I build custom AI automations that live inside real applications — not just Zapier flows sitting on top. If you've outgrown no-code and need someone who can wire OpenAI or Claude directly into your Laravel, WordPress, or SaaS backend, that's the work I do. Background: 8+ years shipping full-stack applications with complex API integrations. Recent work includes a full MVNO subscriber platform for Rockstar Wireless — integrating AT&T, Verizon, and T-Mobile into a unified plan selection → checkout → SIM/eSIM activation → billing flow — and a luxury real estate portal for Immotropical pulling thousands of live listings from the Resales Online MLS API into a custom WordPress plugin. That same integration muscle — carrier APIs, MLS feeds, billing systems — is exactly what makes AI integration work well. Most AI automation freelancers stop at the no-code layer. I build the code layer underneath it. What I do: — AI integrations inside existing apps: OpenAI and Claude APIs, RAG, custom chatbots, LLM-powered features — n8n workflow automation for SaaS ops (CRM ↔ billing ↔ support ↔ email) — Full-stack development: Laravel, PHP, WordPress, MySQL, custom plugins — Complex API integrations: payment gateways, third-party data feeds, CRM/ERP sync — SaaS backends built to handle real operational load Recent AI/automation work: Manual payroll prep is slow, error‑prone and hard to audit, especially with complex shift rules, night/holiday premiums and project‑specific shift definitions. Good fit if you're saying: — "We need an AI copilot inside our SaaS product" — "Our ops team is drowning in manual handoffs between tools" — "We want a RAG chatbot that answers from our internal docs" — "We need to plug an LLM into our existing Laravel or WordPress app" — "Our no-code automation broke and we need a real developer to rebuild it right" How I work: 30-minute discovery call to align on scope, budget, and timeline → written proposal within 48 hours → agile sprints with weekly demos → clean handoff with documentation. I keep communication direct. If a scope isn't going to work, I'll tell you before we start, not after. Available now for new project Message me with a rough brief and I'll come back with a scoping question or two.
