AI Voice Agents — inbound and outbound AI calling systems built on Twilio, ElevenLabs, Vapi, Retell, and Bland AI, integrated with CRMs, calendars, and payment systems for complete end-to-end AI workflow automation. Delivered across real estate, healthcare, restaurants, automotive, and self-storage businesses.
AI Workflow Automation — end-to-end AI automation pipelines on Make, Zapier, n8n, and custom webhook architectures with GoHighLevel and HubSpot integration covering the full lead lifecycle from first contact to closed deal.
AI SaaS Platforms — vertical AI SaaS products with LLM integration, RAG pipelines, agentic AI systems, multi-tenant architecture, Stripe billing, and role-based access, production-ready from day one.
LLM and RAG Systems — custom LLM workflows using OpenAI API and Anthropic Claude, RAG pipelines with LangChain and Pinecone for semantic search, document intelligence, and accurate retrieval from internal knowledge bases and live business data.
AI Chatbots and Assistants — GPT-based conversational AI assistants for customer support, sales intake, lead qualification, onboarding, and internal operations integrated into web and mobile platforms.
Agentic AI Systems — multi-step AI agents that plan, execute, and adapt across tools using LangChain agents, OpenAI function calling, and MCP-compatible architectures for intelligent automation beyond basic chatbots.
Full Stack and Mobile Development — React.js, Next.js, and React Native applications built with production architecture on Node.js, Python, FastAPI, and Laravel when the AI system needs a complete web or mobile product around it.
𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤:
I start with a short discovery conversation to understand your goals, users, and constraints. I define the system architecture, break the build into clear milestones, and deliver iteratively so you always have full visibility. I stay through launch.

🔥 HOW I WORK
I think like a product engineer, not a code-monkey. Before writing a line, I align on the business outcome — who the user is, what they pay for, where the product needs to be in 6 months. Then I ship in weekly demos and stay available on Slack / Telegram for fast turnaround.
Typical cycle:
1️⃣ Discovery & scoping (2–3 days) — define MVP boundary
2️⃣ Architecture — clean foundations, scalable schema, right stack
3️⃣ Weekly sprints with demos — progress every week
4️⃣ Production launch — CI/CD, monitoring, error tracking
5️⃣ Post-launch support — most clients keep me on
