I build AI voice agents and MCP servers that ship to production.

Independent engineer based in Kyle, TX. Voice agents on Twilio and Synthflow that qualify leads, book appointments, and sync to your CRM in real time. Model Context Protocol servers that connect Claude to Meta Ads, Mailchimp, Shopify, and whatever else runs your operation. Fixed scope, fixed price, 7 to 14 days.

Voice agent builds $2K – $4K · 7–10 days
MCP server builds $3.5K – $7K · 10–14 days
Response time Within 24 hours

Three projects. Each one shipped to production, measured in dollars or seconds, and running right now. No case studies about demos that never made it out of a repo.

Voice Agent · SaaS Feature

A SaaS feature that replaces a $1,200/month answering service with a sub-second AI receptionist.

Built as a core feature of a senior living SaaS product at a previous employer. Twilio + Synthflow voice agent with a 7-question qualification flow, real-time GoHighLevel push, and SMS follow-up firing inside 30 seconds of call end. Designed so operators could drop their existing human answering service. System architecture and integration layer were mine.

I'd be happy to schedule a tour. What day works best for you this week?
MCP Server · Internal Tool

Production MCP server. Claude runs an entire DTC brand through natural language.

Built a custom Model Context Protocol server exposing 95 tools across Meta Ads, Mailchimp, Shopify, YouTube analytics, VideoForge, and internal Postgres to Claude. Every write action passes through a confirm-gate so nothing fires without explicit approval. Full audit log. Deployed on a $20 VPS and running daily since March. Same architecture deploys for client ops dashboards in 7 to 10 days.

Campaign Infra · Revenue

17-day product launch. 1.94x blended ROAS across Meta, email, and direct.

Stood up the whole stack for a physical product pre-order: Astro 5 landing page, Shopify checkout, Meta Pixel + native CAPI integration, 10-email Mailchimp sequence, and three Meta ad segments (cold, retargeting, lookalike). EMQ 8.0 confirmed healthy. Warm audience drove 48% of revenue at AOV 3x cold. Clean attribution, clean handoff.

Fixed scope, fixed price. I quote in days, not hours.

50% deposit, 50% on delivery. Code is yours, documented, with a 14-day fix window after handoff. I send Loom updates, not status emails.

What I don't do: demos that never ship. Strategy decks without working code attached. Hourly contracts where scope is "we'll figure it out."

Send a short brief. I'll respond within 24 hours with a fixed quote or a referral if I'm not the right fit.
