Background

About Tony Casey

I'm a Senior AI Engineer and Enterprise Architect with 15+ years building scalable systems across SaaS, e-commerce, and fintech — and for the past few years, my focus has shifted almost entirely to AI.I build production AI systems: multi-agent pipelines, RAG applications, LLM evaluation frameworks, and persistent memory infrastructure for AI coding agents. I care about the full picture — architecture, delivery, observability, and responsible deployment — not just prototyping.A few things I've shipped:🤖 PublicPrep.ie — A live, revenue-generating AI interview prep platform I built solo. It combines Deepgram speech-to-text, LLM-based STAR evaluation (OpenAI + Anthropic), and adaptive question generation. 100+ active users and growing.🧠 Multi-source RAG platform @ Bounce Insights — Architecting a Python-based RAG system using Weaviate for vector retrieval, Langfuse for prompt management, and Pandas to ingest and normalise data from Excel, Firebase, and PDF sources. Open source AI tooling — - Agent Harness (Claude Code orchestration)- Git-Mem (git-backed agent memory)- Lisa (knowledge graph memory with Neo4j + Graphiti).Currently deepening my Python and ML foundations through a Professional Diploma in AI for Software Developers at University of Galway.If you're building AI products and need someone who can take things from whiteboard to production — let's talk. github.com/TonyCasey publicprep.ie.
