Fix ML Systems That Break at Scale

System-level ML audits by a Principal Machine Learning Engineer. I focus on model choice, evaluation, and inference decisions—and how they interact with deployment—to cut latency, reduce costs, and stabilize production behavior. No fluff. Just results.

When You Should Talk to Me

If your ML system behaves strangely, costs too much, or falls apart at scale—I've probably seen why. Here are patterns I diagnose regularly:

Your evals chose the wrong model

Model A beats Model B on benchmarks, but performs worse in production. Offline metrics don't capture real-world failure modes or distribution shifts.

Latency is dominated by what you didn't measure

The model is fast, but end-to-end latency is terrible. Preprocessing, tokenization, or serialization overhead destroys performance.

Fine-tuning improved metrics but broke behavior

Your fine-tuned model scores better but users complain. Objective mismatch or overfitting masked by evaluation blind spots.

RAG works in demos, fails in production

Retrieval quality degrades at scale. Context windows overflow silently. Latency balloons with corpus size.

Prompt drift causes silent regressions

Nothing changed in code, but outputs degraded. Unversioned prompts and templates create non-reproducible behavior.

Costs exploded after deployment

What worked in development becomes financially unsustainable in production. No one modeled the real cost structure.
