Full-stack developer focused on AI agents, support chatbots and workflow automation. I turn AI capabilities into working products — shipped cleanly, on time.
A few projects showing product design, AI conversational apps, and end-to-end automation.
A 24/7 assistant for HVAC and plumbing contractors. It triages emergencies, walks the customer through issue, address and contact in a friendly chat, books the visit and pushes the qualified lead to a live dispatch inbox with a priority score. Fully in-browser demo — no API key needed.
An embedded tutor for online courses and coaching programs. It answers strictly from the creator's own material, cites the exact lesson on every answer, runs quick knowledge checks, and captures prospective students. A creator dashboard shows questions answered, support time saved and satisfaction. Fully in-browser demo — no API key needed.
A support chatbot embedded in an e-commerce storefront. It answers questions about orders, shipping, returns and products, with quick-reply chips, typing indicators and a smooth handoff to a human. Runs on a local knowledge base — no API key needed for the demo.
An automated pipeline that takes inbound leads through classification, data extraction, priority scoring and AI-drafted replies — then routes them to the right place in the CRM. Includes a visual node flow and a step-by-step run log.
A polished, conversion-focused marketing page for a small-team SaaS product, with a product UI mockup, pricing, testimonials and a responsive layout. Built as a single, fast-loading page.
From front-end to AI logic and the integrations that connect everything.
Tell me what you're building. I'll reply with whether it's a fit, a clear scope and a timeline — usually within a day.
