Creative Engineering / 001
Ideas you can
step inside.
Interactive experiments where photography, computer vision, production systems, and large-scale simulation become something you can see and explore.
Enter the first experimentExperiment 001 / Visual criticism
Composition Studio
A vision model analyzes each street photograph for its strongest compositional techniques. The image-specific readings and coordinates are stored in PostgreSQL, then rendered as animated overlays that reveal the lines, layers, color, rhythm, and visual relationships within each frame.

Experiment 002 / Load testing
Simulated City
I helped engineer and create SimulatedRides at Lyft to load-test its two-sided marketplace at massive scale. This interactive homage sends probabilistic riders and drivers through ramp, soak, and recovery. Read the Lyft Engineering article I co-authored

Nominal
Modeled service fan-out based on client actions. Cancels receives traffic only when a rider cancels; Resource Manager receives traffic only as rider and driver resources are allocated or released.
01
Probabilistic clients
Riders request and cancel while drivers accept and complete trips according to configurable behaviors.
02
Ramp, soak, recover
The scenario gradually injects demand, holds its target, then drains synthetic clients safely.
03
Observable outcomes
Marketplace health emerges through throughput, match latency, active trips, and success rate.
