~/sandbox

A live workflow engine, not a screenshot.

This is the architecture behind IntegrateX, running in your browser. Drag the nodes, drag from one handle to another to rewire the graph — every change flows through a Zustand store, the same pattern that powers the production serialization adapter. Pipeline: Webhook Trigger LLM Processor Database Write.

React Flow + Zustand · drag nodes to reposition · drag between handles to connect

Serialization Adapter — live bench

● real bytes, measured from the canvas above
raw React Flow state (what naive persistence stores)1.09 KB
schema-aware struct (what the adapter stores)117 B

Drag a node or wire a new edge above and watch both payloads reprice. The database stores what is true, not what is drawn — styles, dimensions, and handles are derived from the schema on load. The full story →

The Architecture is Everything.

AI handles the syntax; the engineer dictates the flow. Master the pipeline: Database → Backend → Frontend. An AI-equipped architect ships the volume of an entire engineering squad. Hold the reactor to see the difference.

Infrastructure & Resiliency Lab

Interactive demonstrations of production-grade LLM cost governance and client-side network degradation recovery.

FinOps Cost Simulator

Live token economics: naive frontier-only inference vs. a semantic cache + model-cascade architecture, at 2,000 tokens per request.

Naive Stack

$3,000.00

100% frontier model · $15.00/1M tokens

Optimized Cascade Stack

$367.20

Cache hits free · 80% of misses → Flash ($0.075/1M) · 20% → Frontier

Monthly Savings

$2,632.80

87.8% infrastructure deficit reduction

Chaos Engineering Degrader

Inject a synthetic upstream failure and watch the client degrade gracefully: timeout → exponential backoff → local fallback cache. No crash, no blank screen.

~/observability

Every AI request is a trace.

A RAG pipeline you can't see span-by-span is a pipeline you can't debug or price. Run the query cold, then flip the semantic cache on and watch the same question collapse to a handful of milliseconds.

RAG query — trace waterfall

modeled on production trace shapes
"What is Yaseen's tech stack?"

run the query — with the cache off, then on — and compare the totals

~/guardrails

Go ahead — attack it.

Production agents survive adversarial input through layered, deterministic defenses — not polite prompting. Try an injection, leak some PII, ask something off-topic, and watch each layer rule on it.

Guardrail playground — try to break it

deterministic layers · runs in your browser · no model calls

pick an attack — or invent one — and watch each defense layer rule on it

Green thresholds are Google's own (LCP ≤ 2.5s · CLS ≤ 0.1 · INP ≤ 200ms). If you're seeing green on a page running three interactive simulations, that's the performance engineering working.
