I help companies replace repetitive communication with intelligent AI Voice & Chat Agents that work 24/7, sound human, and integrate deeply with CRMs, PBX systems, and business workflows.
I’m an AI Voice & Automation Engineer with 9+ years of experience building scalable, production-grade systems – from AI receptionists and outbound callers to multi-agent orchestration platforms for sales, healthcare, real estate, and operations-heavy businesses.
My focus is not “bots for the sake of bots”, but agentic systems that qualify leads, confirm data, schedule appointments, and move KPIs.
🧠 What I Build
✔ AI Inbound Voice Agents
Handle calls, collect structured data, qualify leads, confirm details, and book meetings via PBX, Kamailio, Asterisk, FreeSWITCH, LiveKit, Twilio, Telnyx.
✔ Outbound AI Voice Agents
Automated follow-ups, lead reactivation, reminders, promotions, and confirmations with real conversational logic.
✔ AI Receptionists (Clinics, Hotels, Services)
24/7 booking, reminders, FAQs, and CRM sync using STT → TTS, SMS, and calendar integrations.
✔ AI Recruiter & Screening Agents
Voice-based candidate screening with multi-layer logic, scoring, and CRM synchronization.
✔ Real Estate & Property Voice Assistants
Answer property questions, book showings, confirm via SMS/email, and sync with CRMs and calendars.
✔ AI Chatbots & Call Assistants
Context-aware conversational bots connected via n8n, Make, Zapier, APIs, and databases.
✔ Custom AI Voice Logic & Agentic Systems
Built with Vapi, RetellAI, ElevenLabs, Ultravox, Claude, GPT, memory, state management, and fallback logic.
🔐 Data Security & Compliance
Security is built-in, not added later.
For healthcare and sensitive industries, I implement:
HIPAA-aligned architectures
Encryption at rest & in transit
Access control & audit logging
Secure API & CRM integrations
⚙️ How It Works
✔ Discovery & Demo – Real use cases, not theory

I build production-ready AI voice agents, chatbots and conversational systems - not demos.
20+ years in software development.
7+ years building conversational AI systems, long before the ChatGPT hype.
I help businesses automate conversations, calls and customer workflows with AI systems that are stable, integrated and ready for real users.
What I can help with:
• AI voice agents for calls, lead qualification, booking and customer support
• Conversational AI systems using OpenAI, Dialogflow CX/ES and custom backend logic
• AI agents connected to CRMs, internal tools, databases and business workflows
• Chatbots for customer support, sales, onboarding and operational automation
• Audits and fixes for existing AI/chatbot/voice systems that are unstable or hard to scale
Most AI projects don’t fail because of the model.
They fail because of weak architecture, poor integrations, missing fallback logic, unclear conversation flows and no proper testing.
That is where I usually help most.
I can design the conversation logic, build the backend, connect external APIs, handle edge cases, add human handoff, improve reliability and bring the system to production.
Core areas:
Voice AI · Conversational AI · AI Agents · OpenAI API · Dialogflow CX/ES · Chatbot Development · API Integrations · CRM Automation · Customer Support Automation
If you need someone who can do more than “connect GPT to a chatbot” - I can help you build an AI system that actually works in production.

Stop paying for manual, repetitive tasks.
Let’s build AI-driven systems that scale your business 24/7.
Imagine having AI agents that not only chat but actually operate your business workflows—processing data, integrating with your CRM, and triggering precise actions across all your apps without human intervention.
As an Automation & AI Solutions Architect, I help businesses eliminate digital friction, bridge technical gaps, and deploy intelligent automation that saves thousands of hours.
WHAT I CAN BUILD FOR YOU
⚡Intelligent AI Agents & Bots: Custom LLM deployments (OpenAI, Anthropic Claude, DeepSeek, Llama) optimized with RAG (Retrieval-Augmented Generation) and Vector Databases. Using Model Context Protocol (MCP), I build autonomous agents that safely interact, reason, and execute actions directly with your local files or cloud data.
⚡Advanced Workflow Automation: Complex, multi-branch scenarios in n8n, Make (Integromat), and Zapier.
⚡AI Voice Assistants & Chatbots: Customer support and lead qualification bots integrated with Twilio, Vapi, or Retell AI.
⚡AI-Driven Data Pipelines: Creating autonomous data-harvesting and processing systems that extract, clean, and pipe unstructured data into AI tools and analytical vector storages.
WHAT I WORK ON (CORE SOLUTIONS)
📂Enterprise AI Integration & API Bridges:
I design secure infrastructure that embeds LLMs (OpenAI, Claude) directly into your native workflows. Using Model Context Protocol (MCP), I build data bridges that allow autonomous AI agents to interact with your internal company resources, cloud storages, or production databases without security compromises.
📂Autonomous AI Agents & Conversational Support Hubs:
I replace rigid, old-school chatbots with context-aware, human-like voice and text assistants for WhatsApp, Slack, Zendesk, or Zoho Desk. These agents autonomously ingest internal knowledge bases via Vector Databases, process incoming support tickets, handle customer refunds, or validate leads, only escalating to human teams when highly necessary.
📂AI-Powered Lead Generation & Sales Outreach Infrastructure:
I build custom end-to-end engines that eliminate manual sales prospecting. The pipeline automatically scrapes targeted industry leads, uses advanced web-scraping to read prospect websites, leverages AI to extract custom hyper-personalized insights ("icebreakers"), pushes them cleanly to your CRM (Zoho, HubSpot), and triggers multi-channel outreach campaigns.
📂Intelligent Document Processing (IDP) & Operations Automation:
I automate heavy manual data entry by building smart document pipelines. The system automatically fetches incoming PDFs, invoices, shipping labels, or contracts, parses them using LLM Vision models to extract structured JSON data, maps the data accurately, and updates your inventory, ERP, or accounting software (Shopify, Uniware, QuickBooks).
TECHNICAL SKILL SET
⚙️Core AI Tech: OpenAI API, Anthropic Claude, DeepSeek, Llama 3, Model Context Protocol (MCP), RAG, Vector Databases (Pinecone, ChromaDB).
⚙️Workflow Automation: n8n, Make (Integromat), Zapier, Zoho Flow, Webhooks, API Integrations.
⚙️Conversational AI: Vapi, RingCentral, Retell AI, Twilio, Voice Assistants, AI Chatbots.
⚙️AI Backend & Scripting: Python (FastAPI, AI Agents logic, Web Scraping), Node.js (Data preprocessing for LLMs).
GOOD FIT IF YOU NEED:
🎯To eliminate "digital slavery" and free up your team's time from copy-pasting data between multiple web tools.
🎯A robust AI infrastructure that safely accesses your databases or internal files to make smart operational decisions.
🎯To scale your customer-facing ops (sales or support) without doubling your headcount, using autonomous voice and text agents.
🎯A specialist who bridges the gap between rapid Low-Code building and custom backend development when standard tools hit a brick wall.
Why work with me?
✅ No-Code Speed + Full-Stack Power: If a tool like n8n or Zapier hits a limit, I write custom Python/Node.js scripts to build flawless API connections.
✅ ROI-Driven: I don’t just build workflows; I design systems that optimize your operational costs and scale reliably.
