Things I've Built
Production SaaS · Full-Stack
DividendCase
dividendcase.com ↗Full-stack fintech SaaS for dividend stock analysis. Portfolio tracking, income calendars, benchmark comparison, watchlists with drag-and-drop. Daily GitHub Actions pipeline fetches S&P 500, FTSE 100, NIFTY 50, TSX 60, ISEQ 20, ASX 200.
Education Platform · Interactive
PhysicStuff
physicstuff.com ↗Interactive physics education platform with real-time browser simulations — Lorenz attractor, Fourier synthesis, Mandelbrot explorer, projectile motion, wave packets. Migrated from WordPress to Next.js.
Python · PyPI Package
Maglimit
Published PyPI package for astronomical observability — determines if an object is observable given its magnitude and a telescope's limiting magnitude. Built at Caltech's CodeAstro workshop.
Where I've Worked
Allied Irish Bank (AIB)
Aug 2025 – Present
Data Engineer
Design and deploy large-scale Python automation pipelines for payment transformation across AIB's PFM systems, with SQL/Azure data integration, Kafka-based event publishing, and Splunk dashboards and ITSI services for payments observability and anomaly detection.
Sep 2023 – Jul 2025
Data Analyst
Completed AIB's Technology Graduate Programme across data engineering, Splunk observability, and payments assurance before converting to Data Engineer. Built ETL utilities in Python, designed Splunk dashboards and integrity alerts for SWIFT/SEPA/Instant Payment monitoring (reduced MTTR), and contributed to the NLP-driven PII anonymisation workstream using Microsoft Presidio.
