Engagements (fixed-scope, remote-first)

Clear deliverables. No fluff. Senior-level focus on every line of code.

Model Audit
5–7 days
Know if your model is overconfident, leaking, or drifting — with a clear fix plan.
Calibration + reliability analysis Leakage + feature sanity checks Drift monitoring recommendations Evaluation pack (log-loss / Brier)
Forecasting / Pricing Sprint
10 business days
From raw data to a working predictive system you can run, monitor, and trust.
ETL → modelling → validation Calibration + decision thresholds Dashboard/report + handover Reproducible runs + runbook
Monitoring & Iteration
monthly
Models stay honest in production — performance tracked, drift detected, fixes shipped.
Drift alerts + threshold triggers Performance reporting + review Iteration roadmap + improvements Retraining plan (when needed)
ACCURATE
Calibrated probabilities + proper scoring rules (log-loss, Brier, reliability).
FAST
Automated pipelines + reproducible runs built for decision velocity.
RELIABLE
Monitoring, drift checks, and handover documentation for production use.
Async-friendly. Minimal meetings. Maximum shipping.

How it works

A structured delivery process designed for remote execution and fast impact.

1
Scope call (30 minutes)
Define objective, data access, constraints, and the success metric. Minimal meetings, maximum clarity.
2
Sprint delivery
Working demo mid-way, weekly update, and a build you can run end-to-end.
3
Handover + next steps
Runbook, monitoring plan, and an improvement roadmap — so the system keeps paying you back.

I take on a limited number of consulting projects to ensure senior-level focus on every line of code.
