Build production ML: leakage-free features, correct validation, honest metrics, tuning and serving.
- Feature engineering with leakage prevention
- Model choice: linear, tree ensembles (XGBoost/LightGBM), neural nets
- Cross-validation, honest metrics vs baselines, calibration
- Hyperparameter tuning, reproducibility and model serving
ML engineers who want correct, leakage-free models and honest evaluation, not inflated metrics.A senior ML engineer bills $120+/hr, this is one file, yours forever.
// what's inside
Drop Arjun into Claude and get a senior ML engineer who builds leakage-free models, validates them honestly, and ships them to production.
Arjun frames the problem, engineers features without leakage, picks the right model (linear, tree ensembles like XGBoost/LightGBM, neural nets), validates with proper cross-validation and honest metrics against a baseline, tunes hyperparameters, calibrates, and serves the model reproducibly. Always validate on a held-out sample in dev/staging, version data, code and models, and review before production.
What you get
- →Feature engineering with leakage prevention
- →Model choice: linear, tree ensembles (XGBoost/LightGBM), neural nets
- →Cross-validation, honest metrics vs baselines, calibration
- →Hyperparameter tuning, reproducibility and model serving

How to install
Download the .skill package → open Claude → paste SKILL.md into your Project Instructions or system prompt → describe your requirement → Arjun builds the answer. Includes a full worked example so you see exactly what you get.
# Arjun — Machine Learning Engineer You are Arjun, a senior ML engineer. You build leakage-free models, validate honestly against a baseline, and ship them to production. ## How you work 1. Frame the problem and the metric 2. Engineer features without leakage; choose the model 3. Cross-validate; report honest metrics vs a baseline; calibrate 4. Tune, make it reproducible, and serve; validate on a held-out sample Always validate on a held-out sample in dev/staging; version data, code and models; never ship inflated metrics.
Excerpt from the actual file you'll download.
// try it
$Build a churn model. Make sure there is no leakage and the metrics are honest.
Arjun builds a leakage-free sklearn Pipeline, uses the right cross-validation, reports honest metrics against a baseline, calibrates, and gives a serving plan, all validated on a held-out sample.
