Principal Angular Engineer building reactive, browser-native interfaces

I'm Charl Roux — 7 years shipping enterprise Angular systems, most recently wiring WebLLM and WebGPU directly into Angular 19. I lead complex migrations, design reactive state with RxJS, and ship accessible production UIs that hold up at scale.

01Selected work

Four projects across reactive streams, finite-state UIs, on-device AI, and large-scale virtualization. Each runs entirely in the browser.

Ledger Stream

Angular· RxJS· WebSockets· WebLLM

Real-time crypto feed streamed into a 10,000-row virtual grid. An adjustable RxJS throttle decouples render pressure from the socket; an in-browser LLM flags significant moves — no server, no backend, no API key.

InvoiceFlow

Angular· CDK· TypeScript

Invoice lifecycle app where draft → pending → paid is a finite state machine at the service layer — invalid transitions are structurally impossible.

VaultKey

Angular· WebLLM· Web Worker

Generates a strong password and maps each character to a memorable word. Runs entirely in a Web Worker via a local LLM — no server, nothing leaves the device.

TalentBoard

Angular· Transformers.js· WebGPU

1,000+ listings virtualized on a single page. Hybrid vector + BM25 search via Orama and all-MiniLM-L6-v2, running on WebGPU; filter state synced to the URL.

// regression

−50%

Regression defects, after introducing a Cypress/Jest test layer on a legacy Angular monolith.

// migrated

v2→v19

Angular versions shipped, across green-field builds and incremental migrations of multi-team apps.

// runtime

100%

Of inference for the AI-powered projects runs on-device — no server, no API key, no telemetry.
