Do.
I build systems that investigate software, evaluate AI behavior, and turn complex failures into evidence engineers can use.

The work
AI is useful when you can inspect its decisions.
My work brings investigation, end-to-end AI testing, response evaluation, and load testing into systems where evidence stays visible. Select a project below to explore a synthetic example of the problem it addresses.
Selected systems
Four projects.
Different kinds of proof.
Each demonstration has its own interaction and a concrete outcome. No live Adobe systems, customer data, internal URLs, credentials, logs, or proprietary details are connected.
01 / Investigate
InK-9 AI
A Master agent plans an investigation, routes bounded work to specialists, and returns an evidence-backed finding.
The investigation remains open.
Select each stage to follow the evidence before reaching the final result.
Illustrative walkthrough. Synthetic content only; no live Adobe system, internal URL, credential, customer information, or production endpoint is connected. Echo Loads figures describe one supplied sample run.
