A decade of the whole stack: firmware to frontend, photonics to computational biology, hardware benches to Kubernetes clusters. When the problem crosses layers — that's the specialty.
The frontier is the day job.
The multidisciplinary decade is the foundation. The daily practice is at the leading edge of agentic AI:
What used to take a team and a quarter now assembles in weeks — if the builder knows both the old world and the new one. That's the acceleration on offer.
The work this practice loves:
- An AI platform that doesn’t exist yet — and needs to, end to end.
- An instrument, a lab, a production line that needs a brain.
- The pipeline your scientists still run by hand.
- The system everyone says needs a team of five.
- Agents that have to work unattended, with receipts.
If it’s genuinely hard and crosses disciplines, it’s probably a fit.

Crystal is the founder and lead engineer of Activated Human — a multi-product AI platform running on its own infrastructure, with company operations run by an agent swarm she designed. Along the way, she embedded at a New York cloud-software company and designed, built, and launched their complete agentic AI platform — first architecture to public launch, in under five months. Earlier: three years at Klaviyo on systems supporting billions in platform revenue, and production distributed systems at Paradigm, an institutional network clearing $10B+ monthly.

Embed. Build. Hand over.
I embed with you, build with full AI leverage, and hand over a running system — documented, tested, with your team trained on it. Ongoing support if you want it; independence if you don’t. Then it’s yours.
