AI Ops Team

## Overview

Getting an AI model working in a notebook is easy. Getting it to work reliably in production — with consistent quality, observable behavior, manageable costs, and the ability to improve over time — is where most AI projects struggle. The AI Ops Team closes that gap.

This team is designed for engineering organizations building AI-powered products: LLM-based features, recommendation systems, classification pipelines, or any system where machine learning outputs directly affect user experience or business decisions. The team brings together the disciplines needed to build AI systems that are accurate, reliable, observable, and continuously improving.

  - Build ML pipeline infrastructure: feature computation, training jobs, evaluation, and deployment
  - Implement model registry and versioning using MLflow or similar tools
  - Configure model serving infrastructure with appropriate compute (GPU/CPU) and auto-scaling
  - Set up model monitoring: prediction distribution drift, input feature drift, latency, and error rates
  - Build automated retraining pipelines triggered by model performance degradation signals
  - Implement A/B testing infrastructure for gradual model rollouts with automated rollback
  - Manage feature stores for consistent feature computation between training and serving
  - Build CI/CD pipelines for ML code: data validation, training, evaluation, and deployment steps
  - Instrument LLM API calls for cost tracking, token usage monitoring, and latency observability

## Workflow

1. **Problem Framing** — The AI Engineer and Data Scientist frame the problem: is this a classification task, a generation task, or a retrieval task? Model selection and architecture follow from this framing.
2. **Data Assessment** — The Data Scientist assesses available training data and ground truth. The Model QA Specialist designs the evaluation framework and golden dataset.
3. **Prototype Development** — The AI Engineer builds a working prototype. The Prompt Engineer designs and tests prompt templates. The Data Scientist trains any required fine-tuned models.
4. **Evaluation Baseline** — The Model QA Specialist runs the evaluation benchmark against the prototype. Baseline quality scores are established before any optimization.
5. **Optimization Cycles** — The Prompt Engineer iterates on prompts. The Data Scientist experiments with model variants. The Model QA Specialist evaluates every change against the benchmark.
6. **Production Readiness** — The ML Ops Engineer builds the serving infrastructure, monitoring, and CI/CD pipeline. The Model QA Specialist runs safety and robustness tests.
7. **Production Monitoring** — The ML Ops Engineer monitors drift and cost. The Model QA Specialist runs periodic evaluation benchmarks. The team meets weekly to review production behavior.

## Use Cases

- Building a production RAG-powered knowledge base or chatbot
- Deploying a fine-tuned model for domain-specific classification or extraction
- Implementing AI-powered recommendations in a product feature
- Auditing an existing AI system for quality, bias, and safety issues
- Building the MLOps infrastructure for a team transitioning from research to production
- Setting up model monitoring for a deployed AI system that is drifting without detection

## Getting Started

1. **Start with problem framing** — Brief the AI Engineer on your use case. Is it generation, classification, retrieval, or an agent? The architecture decision flows from here.
2. **Define quality before building** — Ask the Model QA Specialist to help you define what "good" looks like for your AI feature. You need an evaluation framework before you have anything to evaluate.
3. **Assess your data** — The Data Scientist needs to understand what data you have, how it was collected, and what biases it might contain. Start this conversation early.
4. **Plan for production from day one** — Ask the ML Ops Engineer to design the serving and monitoring infrastructure at the same time the first prototype is built. Retrofitting MLOps is painful.
