Synthetic digital-banking analytics from lifecycle metrics and causal estimates to churn ranking and contact economics.
Built a deterministic 100,000-customer evidence layer in DuckDB with explicit activation, retention, campaign, churn, monitoring, and economics contracts.
Measured a +9.16 percentage-point randomized activation effect, then showed that every simulated strategy that contacted customers lost value under the fictional cost assumptions.
Offline MEA spike detection, burst analysis, waveform metrics, and electrode comparisons.
Built a local Streamlit workflow for continuous recordings and pre-sorted NeuroExplorer spike data, covering spike, waveform, ISI, firing-rate, and burst analysis.
Added deterministic regression fixtures for burst algorithms, filtered detection, waveform boundaries, and EDF calibration; these checks validate implementation behaviour, not biological validity.
Citation-grounded research across financial documents using hybrid retrieval and reranking.
Combined BM25 and vector retrieval with reciprocal-rank fusion, company-balanced retrieval, cross-encoder reranking, and page-resolved citations.
Recorded 19/19 evaluation checks on three real SEC filings and 290 passing backend tests, while documenting live-use failures and remaining retrieval limitations.
Venue-calibrated ML paper evaluation built from historical OpenReview evidence.
Built a leakage-safe, forum-level evaluation workflow with closed model inputs, private labels, disjoint calibration sets, and hash validation.
Across descriptive ICLR pilots, calibration reduced rating MAE by 21.8%, increased decision accuracy from 62.9% to 77.1%, and reduced false accepts from 9 to 2.
