Systems
Architecture visuals for live-system reliability work.
Selected diagrams, telemetry surfaces, and anonymized control planes. Enough to show operating caliber without publishing raw implementation detail.
Walkthroughs
Three public patterns. Raw artifacts stay private.
Release control
Deterministic rollback pipeline
Promotion gates, canary comparison, rollback drills, and shared model plus infrastructure telemetry.
Execution state
State-persistent execution testing
Session snapshots, restart primitives, replayed market sessions, and invariant catalogues.
Operator surface
Execution telemetry and control surfaces
Risk sliders, quote state, system health, workstream closure, and exception response surfaces.
Deterministic rollback pipeline
Release paths are treated as operating systems, not checklists.
Model promotion, canary comparison, telemetry thresholds, and rollback are wired into executable gates. The public story is the control pattern, not the client's pipeline code.
State-persistent execution testing
Test the state the system actually carries.
Restart, overnight, partial-fill, reconnect, and reconciliation paths are validated with snapshots and replayed sessions. The public artifact explains the method without exposing venue-specific internals.
Telemetry and execution surfaces
Anonymized dashboards and operator-facing control planes.
Boundary
Public evidence, private implementation.
Client-sensitive data, raw logs, dense source documents, and speculative notes remain private. Public systems pages show reusable architecture patterns and anonymized proof.
