LLM Healthcare Job Classification

See a live demo of an LLM pipeline classifying and structuring thousands of healthcare jobs weekly, using OpenAI for specialty, shift, and experience, with real code and prompt engineering insights.

Node.js Puppeteer PostgreSQL/Prisma Next.js Workday m-cloud Node Next OpenAI API Claude Code

Overview

Live demo of a production system that scrapes nursing jobs from 15+ healthcare employers (Workday, Symphony Talent, Phenom APIs), then uses OpenAI API to:

Classify jobs by specialty, shift type, experience level, and remote/hybrid/onsite
Transform messy ATS descriptions into structured, readable formats using employer-specific prompts

I’ll show the actual code, the prompt engineering decisions, and how we handle edge cases like insurance companies vs hospital systems needing different formatting rules.

Tech stack

Node.js

Node.js is a V8-powered JavaScript runtime (open-source, cross-platform) for building fast, scalable network applications and server-side logic.

Node.js runs JavaScript outside the browser, leveraging Google's high-performance V8 engine. Its core strength is the event-driven, non-blocking I/O model (asynchronous operations), which makes it ideal for building highly scalable, real-time applications: think chat services or high-throughput APIs. The platform is backed by npm (Node Package Manager), the world's largest software registry, offering developers over 2.5 million packages for rapid development and deployment. We use it for everything from microservices to command-line tools, ensuring efficient resource utilization.

Puppeteer

Puppeteer is a Node.js library: control Chrome and Firefox (headless or full) via a high-level API for automation, testing, and scraping.

Puppeteer is the Node.js library for high-level browser automation: it controls Chrome, Chromium, and Firefox via the Chrome DevTools Protocol (CDP). This API is essential for automated UI testing, running scripts across Chrome and Firefox (now with WebDriver BiDi support), and critical tasks like web scraping. Use it to generate high-fidelity PDFs, capture full-page screenshots, or emulate complex user flows: simply call methods like `page.goto()` and `page.click()` to drive the browser, headless or full.

PostgreSQL/Prisma

The gold standard for type-safe database access: pairing PostgreSQL's relational power with Prisma's automated migrations and intuitive TypeScript client.

This stack eliminates manual SQL mapping by generating a type-safe client directly from your PostgreSQL schema. Define models (like User or Post) in the schema.prisma file to handle relations through foreign keys. Prisma Migrate tracks every structural change in a dedicated migrations folder, keeping dev and production environments in sync. It supports PostgreSQL versions 12 through 16: providing native support for JSONB, full-text search, and complex joins without traditional ORM boilerplate.

Next.js

Next.js is the production-ready React framework for building full-stack web applications: it delivers superior performance via hybrid rendering (SSR, SSG) and automatic code optimization.

Next.js, created by Vercel, is the definitive React framework for high-performance web applications. It extends core React with essential production features: hybrid rendering (Server-Side Rendering and Static Site Generation), file-system-based routing, and built-in API routes for full-stack capability. The platform leverages powerful, Rust-based tooling (like SWC and Turbopack) to ensure faster builds and optimized output. Major companies like Walmart and Netflix rely on Next.js to deliver fast, SEO-friendly, and scalable user experiences (UX).

m-cloud

mCloud's AssetCare platform uses AI and IoT to optimize energy performance and equipment reliability for global industrial operations.

AssetCare connects critical infrastructure (like wind turbines and commercial HVAC systems) to a centralized cloud environment for real-time monitoring. It currently tracks over 63,000 assets across 10 countries: providing operators with predictive maintenance alerts that prevent costly failures. By analyzing high-frequency sensor data, the system cuts energy waste by up to 25% and ensures peak efficiency for heavy industry players in the oil and gas sectors.

Node

Node.js is a high-performance JavaScript runtime built on the V8 engine for executing scalable network applications.

Ryan Dahl launched Node.js in 2009 to rethink server-side concurrency. It utilizes an event-driven, non-blocking I/O model to manage thousands of concurrent connections on a single thread. The system runs on Google's V8 engine (C++) and provides access to npm (a registry with over 2 million packages). Companies like Netflix and LinkedIn use it for its speed and scalability: it remains the top choice for real-time data streaming and microservices.

Next

Next.js is the full-stack React framework: it delivers high-performance web applications via hybrid rendering and powerful, Rust-based tooling.

This is the React Framework for production: Next.js enables you to build full-stack web applications with zero configuration and maximum efficiency. It supports a hybrid rendering approach (Server-Side Rendering, Static Site Generation, and Incremental Static Regeneration) for optimal speed and SEO performance. Key features include React Server Components, Server Actions for running server code directly, and the App Router for advanced routing and nested layouts. Developed by Vercel, it leverages Rust-based tools like Turbopack and the Speedy Web Compiler for the fastest possible builds and a superior developer experience.
