I'm an AI Developer, Full-stack developer, and Solution Architect who builds automation that runs your ops like a digital employee, not a fragile trigger chain. As an AI Developer, I design each AI Agent to think, decide, and self-correct, so it works like a teammate, whether it powers an AI SaaS product or your daily ops, with Claude as the reasoning engine. That is the core promise of an AI Developer: systems that reason, not just react. A real AI Developer ships logic, not glue, and as a Full-stack developer I build the product around it end to end. Agentic AI is what turns that logic into a system. Most businesses don't have an automation problem; they have a system design problem, the kind a Solution Architect catches and an AI Developer solves. Workflows break on n8n, Make, and Zapier because no one engineered the logic underneath. I fix that with Agentic AI, powered by Claude, that holds up in production. That backbone runs through every AI SaaS I build, because the reasoning layer is the product, and the app around it has to be just as solid. Top 1% Upwork · 100% Job Success · 5.0 Rating · $100K+ Earned · 686+ Hours · 34+ Projects WHAT I BUILD: As an AI Developer, I give each tool one job: n8n for orchestration, Make for data transformation, Zapier for integrations, and Claude as the reasoning engine. As a Solution Architect, I make those systems qualify leads, sync HubSpot, Salesforce, and Airtable, and run support triage 24/7 with an AI Agent at the core. When you need a product, I ship full AI SaaS platforms on Claude, and as a Full-stack developer I own the frontend, backend, and database myself. This is the discipline an AI Developer and Solution Architect bring that an integrator cannot, which is why my Agentic AI work ships as a true AI Agent built to AI SaaS standards. Agentic AI is the difference between a script and a system. RECENT RESULTS: SaaS sales engine: an AI Agent on Claude cut lead response from 4 hours to under 4 minutes, $9K/month saved. Built as Agentic AI on Claude. Agency pipeline: one agent across 12 accounts saved 120 hours/month, 65% faster. Mapped by an AI Developer using Claude. Support triage: an AI Agent resolves 60% of Tier 1 tickets untouched, 80% faster, Claude at the reasoning layer. Built into an AI SaaS layer on Claude. AI app: React/Next.js, Node.js/PostgreSQL, shipped by a Full-stack developer with Claude in the core. Clients save 100-200+ hours/month, cut workload 30-60%, and hit ROI in 30 days, the return an AI Developer and Solution Architect produce with every system and AI SaaS they ship. TECH STACK: Automation: n8n · Make · Zapier AI & Agents: OpenAI · Claude (Anthropic) · LangChain · RAG · Agentic AI · AI SaaS design Backend: Node.js · Python · PostgreSQL Frontend: React · Next.js Integrations: HubSpot · Salesforce · Airtable · Shopify · WooCommerce HOW I WORK: As an AI Developer, I start with a free audit, then decide where each tool adds value and where the AI Agent, often Claude-driven, owns the decisions. What separates a real Solution Architect from one who just connects APIs is what separates a real AI Developer from an integrator: designing each AI Agent for the hard cases, failure edges, rate limits, malformed inputs, with self-correction built in. Agentic AI only earns trust when it survives those edge cases, and as a Full-stack developer I make sure the surrounding AI SaaS holds up too. Everything I deliver as a Solution Architect is stable, documented, and built to scale the way AI SaaS demands. As an AI Developer, I build each AI Agent once and build it right on Claude, so it runs without you. As a Full-stack developer, I stand behind the whole system, not just the glue between APIs. A dedicated AI Developer ships work you can trust, and your Solution Architect stands behind every system on Claude. A Solution Architect designs the system and a Full-stack developer builds the product, but an AI Developer who is also a Solution Architect and Full-stack developer covers all three, and is accountable when it ships. That is what Agentic AI, done right, demands. WHY AN AI DEVELOPER, NOT AN INTEGRATOR: An integrator connects apps; an AI Developer engineers decisions a Solution Architect would stand behind. An AI Developer plans for the day an API fails or an input arrives malformed, and builds the AI Agent to recover on its own; that is the Agentic AI edge. That reliability is what I'm paid for, and why I earn repeat work long after the first AI SaaS ships on Claude. An AI Developer who thinks like a Solution Architect and builds like a Full-stack developer is who you hire to stop rebuilding broken automations. Send your use case and I'll reply with a personalised Loom showing the AI Agent in action, a free audit from your AI Developer, Full-stack developer, and Agentic AI specialist on Claude. Bring the problem; your AI Developer brings the system.
