SiLab — Financial Compliance Platform
01Overview

A full-stack compliance-intelligence platform for a bank's product team. I built the B2B SaaS interface, the live data layer, and the RAG pipeline behind it.

02What I built
  • Design system

    Built an OKLCH token system, a persistent app shell across seven routes, and a full primitive set (buttons, cards, status badges), with the AI-slop tells kept out and real hydration and DB crashes fixed.

  • Modern RAG

    Replaced a heavy self-hosted R2R server with MongoDB Atlas Vector Search plus OpenRouter, over a curated corpus of AMLA, Data Privacy Act, BSP and SEC rules.

  • Section-level analysis

    The analyzer flags violations section by section and cites the exact regulation it conflicts with, Grammarly-style.

  • Hardened after review

    Gated paid admin endpoints behind a token, made seeding idempotent, and capped input size and concurrency so anonymous callers can't amplify LLM cost.
