You will get a Custom AI Voice Agent for Customer Support or Sales
Project details
I'll build a custom AI voice agent that handles inbound and outbound calls for your business — customer support, appointment scheduling, lead qualification, or sales follow-ups. Your agent will sound natural, understand context, and integrate directly with your CRM and phone system.
What you get:
• A fully configured AI voice agent with custom call flows and scripts
• Speech-to-text and text-to-speech pipeline using GPT-4 and Whisper
• Integration with your existing tools (CRM, calendar, helpdesk)
• Call analytics dashboard and conversation logging
• Full documentation and team training
I use proven platforms and APIs to deliver voice agents that handle real conversations — not robotic IVR menus. Whether you need to automate 50 or 5,000 calls per day, I'll build a solution that scales with your business.
Let's talk about your use case — I'll design a voice agent that works around the clock so your team doesn't have to.

What I deliver:
-- Full HubSpot Implementation: Portal setup, object customization, pipeline design, lifecycle stages, lead scoring, attribution reporting. Marketing Hub, Sales Hub, Service Hub, Operations Hub — I build them all from scratch or fix what's broken.
-- AI-Powered Automation: Custom AI agents that live inside your HubSpot workflows — intelligent lead routing, AI-drafted email sequences, chatbot-to-pipeline handoffs, predictive deal scoring, and automated follow-ups that actually sound human.
-- Migration and Integration: Moving you from Salesforce, Zoho, spreadsheets, or any legacy system into HubSpot cleanly. API integrations with your existing tools (Slack, billing systems, support platforms, custom apps).
-- RevOps and Reporting: End-to-end revenue operations — from marketing attribution to closed-won analysis. Custom dashboards, workflow automation, and the data architecture to make your CRM a single source of truth.
Background: Former Microsoft PM (AI and M365), Stanford MS. I've built CRM and AI systems for companies ranging from seed-stage startups to enterprise teams. HubSpot certified in Inbound Marketing and Sales Software.
I work fast, I communicate clearly, and I build systems that your team will actually use — not shelf-ware. If you need a HubSpot expert who also builds AI, let's talk.
