About me
I’m Marc. I build AI calling systems that hold real conversations, qualify leads, book appointments and follow up around the clock, so your team never dials a number. Unlike auto dialers that play recordings, mine listen, understand and reply in natural speech in real time. Built end to end: SIP telephony, streaming speech recognition, an LLM conversation engine with guardrails, natural voice synthesis, and a full campaign dialer with answering machine detection, smart retries and calling-window controls. Your best sales rep at a fraction of the cost, zero downtime. Let’s build it.... Read more

Work experience

NICE

Contact Centre AI Solutions Consultant

NICE • Part-time

May 2025 - Present • 1 yr 6 mos

As a Contact Centre AI Solutions Consultant: 1. Discovery and needs assessment. Audit the client’s call volumes, peak times, common call types, current costs and pain points (missed calls, long wait times, high staffing costs). 2. Use-case selection: Decide which calls the AI should handle (FAQs, appointment booking, payment reminders, lead qualification) and which should stay with human agents. 3. Choose the platform (Vapi, Retell, GoHighLevel, or an enterprise platform) and design the call flow, escalation rules and fallback paths. Plan the integration with their telephony (VoIP, SIP trunk, 3CX, Twilio), CRM and calendar. 4. Write the scripts, prompts, tone of voice and knowledge base so the agent sounds on-brand and handles interruptions and unclear requests well. 5. Implementation oversight. Work with developers or build the integrations yourself (n8n, Make, APIs, webhooks), and manage the project timeline
