Senior Angular Developer building reactive, browser-native interfaces

I'm Charl Roux — nearly seven years building production Angular and TypeScript platforms, four of them as frontend team lead on an enterprise cybersecurity SaaS platform through Nov 2025. I took its codebase from Angular v2 to v19 without a rewrite or feature freeze, cut the main bundle from 400 KB to 250 KB, and built the shared API, auth, and permission-routing layers the product runs on. I'm now extending that experience into Python-backed AI applications, starting with DocLocal.

01Current work

One project, built in the open: retrieval-augmented document Q&A where every answer cites a passage you can check. Angular and Nx in the browser, a Python/FastAPI backend on NVIDIA NIM behind it.

DocLocal interface: a question about a synthetic Falcon rover manual answered with a numbered citation, and the cited passage highlighted in the PDF viewer alongside

DocLocal

Angular· TypeScript· Python· FastAPI· NVIDIA NIM

PDF question-answering with retrieval-augmented generation (RAG): the passages most relevant to each question are retrieved from the document and sent to the model with it. Every answer cites its source — click a citation to jump to the highlighted passage in the PDF and check it yourself.

The live build is Angular 21 and Nx against a Python/FastAPI backend on NVIDIA NIM cloud models — no model download or local GPU — with streamed answers, mid-stream cancellation, and session recovery. It is invite-only; request access from the sign-in page. That path sends document text and questions to NVIDIA.

The earlier fully in-browser path — Transformers.js embeddings in a Web Worker and WebLLM inference on WebGPU, with a SharedWorker so every open tab shares one model — is kept in the repository but is not part of the shipped app.

Per-release regressions, roughly halved by Cypress and Jest suites wired into the DevSecOps pipeline.

Angular versions, migrated incrementally on a live cybersecurity SaaS platform — no rewrite, no feature freeze.
