Alex Horn

Delivered production AI applications for the NSW public education system. Worked on AI features and platform capabilities supporting education workflows, with a focus on reliability, safety, and operational readiness in production environments.

Developed optimization capabilities for data-driven AI solutions for retail assortment and space planning. Scaled from a proven data product to support a growing customer base while delivering end-to-end full-stack and platform improvements. Built and maintained production components including an EduChat departmental chatbot with robust RAG on Azure OpenAI, a centralized document-parsing service (Python/FastAPI) with scalable sync/async workers plus LLM vision extraction, and an agentic model orchestrator that escalates complex STEM queries to advanced reasoning models to optimize latency and API cost. Implemented feature flagging with optimized frontend rollouts, engineered state-preserving interactive tutorial architecture, added security with role-based LLM content filtering and rate limiting, evolved a semantic search engine for broader adoption, and contributed to architectural refactors that reduced AI-generated technical debt.

Built fleet management solutions including novated leasing, vehicle funding, and salary packaging services. Delivered software improvements and supported platform functionality in a business-critical domain.
