A B2B data platform for treasury teams at Automation Boutique: Python pipelines that collect and clean treasury data, a React dashboard on top, MongoDB and Docker on Azure. I own the technical execution end to end, production deploys included.
VBA macros that plug Xero's accounting API straight into Excel. I wrote the whole OAuth2 flow myself, including the part where Internet Explorer used to live.
An interactive Tableau dashboard on global energy use: country comparisons, growth rates, and how the energy mix shifts over time.
Why legacy SFTP connections remain the backbone of bulk data exchange in B2B finance, and what building treasury software taught me about respecting boring tools.
How I went from Big Four accounting to a remote software engineering role, and the faith that carried me through two years of rejections.
A practical walkthrough of implementing OAuth2 authentication in VBA to connect Excel with the Xero API.
