Most AI integrations fail quietly.
The demo works, the prototype impresses —
then it hits production and can't handle
real load, real latency, real users.
Director of Engineering, Hyperbond Studio
I've spent fifteen years making sure that doesn't happen. I don't just consult on AI — I build it myself, which means I know where voice pipelines break under load, where agents fail on edge-case queries, and what production-ready actually means.
Fifteen years of shipping production web systems — WordPress, Shopify, custom SaaS — is exactly why my AI work survives production. Currently Director of Engineering at Hyperbond Studio, building Call Me Sensei, and shipping my own tools on the side.

02 The specialization Where most of my last five years went.
Voice AI, end to end —
from phone call to reply in under a second.
☎ Caller Phone · SIP · WebRTC
◉ Hear Deepgram · Whisper ASR
✳ Think LLM agent · memory · tools
∿ Speak Real-time TTS · emotion
⟳ Reply sub-second round trip
Phone-call AI agents
Full telephony pipelines — inbound and outbound calls answered by agents that listen, reason and respond naturally.
Real-time transcription
Streaming ASR with word-level timestamps, speaker handling and live subtitles — built for production load.
Echo & interruption handling
AEC, barge-in and voice-activity detection tuned on real devices — the unglamorous parts that make voice feel human.
Memory & emotion
Long-term memory and emotional TTS so conversations carry context and warmth across sessions.

06 Also — WordPress
Fifteen years of WordPress
came before the AI.
Long before voice pipelines, I shipped 200+ WordPress and Shopify builds for enterprise clients — custom plugins, integrations, and rescue missions on sites nobody else would touch. That muscle is still here, now with AI wired in where it earns its keep.
- Custom themes & plugin engineering
- WooCommerce & Shopify integrations
- AI features inside WordPress — search, chat, content ops
- Performance rescues & migrations
