Projects
Ten data systems that ran, or still run, in production: continuous ingestion, accounting reconciliation, failure recovery and predictive modeling. The corporate cases appear anonymized for confidentiality, with no company, client or counterparty names, and no financial volumes. What remains is the architecture decision, the trade-off and the mechanism holding the result up. The one exception is the LCK Spring 2024 dataset, public on Kaggle and auditable by anyone.
