Description

Full-Stack TypeScript developer specializing in production-ready AI agents.

Live demo: call zero nine seventy-four ninety-nine fifty-six thirty-one — the AI picks up 24/7.

What I deliver:

1. Receptionist Agent (phone + WhatsApp + chat)

The AI picks up, speaks naturally, books appointments, transfers to a human if needed. Twilio + OpenAI

Realtime API. Embeddable web chat widget.

2. Email Agent (sorting, replies, auto-reminders)

Connects to Gmail/Outlook/IMAP. Sorts emails, replies with business context, reminds after 3 days. 200+ emails/month processed, 50 hours saved.

3. Sales Agent (qualification + nurturing)

Receives a lead, sends an email + WhatsApp sequence over 7-14 days, qualifies (budget, timing, need), books appointments in Google Calendar.

4. AI API Cost Optimization

70-90% reduction: semantic caching, token management, Haiku/Sonnet cascade. Proven results: $0.10 → $0.01/interaction.

My commitment:

- The client pays for their infrastructure (Twilio, OpenAI) — all under their name

- You own everything (code, accounts, data)

- Live demo before quote

- Optional maintenance after delivery
