Production ML, Not Notebook Demos

RAG systems, AI agents, and predictive models that ship to real users.

What I build

RAG Pipelines

Embeddings, retrieval with confidence scoring, citation surfacing. pgvector, LangChain, FastAPI. Served as REST API or embedded widget.

AI Agents with Real Tool Access

Multi-agent orchestration via CrewAI. MCP servers connecting agents to SQL databases, internal APIs, and documentation repos, not toy chains.

Predictive ML for Tabular Data

Classification, regression, and anomaly detection using CatBoost, XGBoost, LightGBM, and ensembles. Benchmarked against your baseline, not just cross-validated in a notebook.

OCR & Document Extraction

Structured JSON extraction from scanned PDFs. Azure Document Intelligence or in-house GLM-OCR depending on cost/accuracy tradeoffs.

Recent work

CompuCal ML Platform

Production ML features shipped inside CompuCal's regulated calibration-management platform. RAG over internal documentation, OCR pipelines for scanned certificates, predictive-maintenance models, and MCP servers giving AI agents real database access.

ReviveMap

3rd place at the Google Hackathon. A map-based platform that helps communities identify and revive neglected public spaces, with AI-assisted categorisation of user-submitted reports.

FinBERT + XGBoost Stock Prediction

Combines FinBERT sentiment extraction from financial news with gradient-boosted price-movement models. Benchmarked against a naive baseline with walk-forward validation rather than random splits.

NeuroMind System

Multi-agent orchestration built on CrewAI. Agents coordinate research, planning, and execution steps with tool access to external APIs rather than isolated prompt chains.

How I work

I work async-first and document as I go. Paid 2-hour scoping call before any engagement over 20 hours so we both know the scope is real. Fixed-price for well-defined deliverables, hourly for open-ended exploration. Based in Cork, Ireland, EU business hours with meaningful overlap for US east-coast mornings.
