Foundation Level (Months 1–6)
Goal: Build your technical foundation in programming, data manipulation, and machine learning fundamentals. Get comfortable with the core tools of the trade.
Core Knowledge Areas
Programming and Development Tools
You need to become proficient in the tools that AI practitioners use daily. Focus on components classified as Technology in the SFIA dimension:
Developer Tools (IDEs, CLI, Version Control) Master a modern IDE — VS Code is the standard for most AI work. Learn command-line tools for file manipulation, environment management, and remote server access. Become proficient in Git: branching, merging, pull requests, and collaborative workflows on GitHub.
Python Ecosystem Python is the lingua franca of AI. Master the core language, then build expertise in the data science stack: NumPy for numerical computing, Pandas for data manipulation, Matplotlib and Seaborn for visualization. Understand virtual environments and package management with pip and conda.
Compute Resources (Cloud, GPU) Learn how to provision and use cloud compute resources. Understand the difference between CPU and GPU workloads, and when you need each. Get hands-on experience with at least one major cloud provider (AWS, GCP, or Azure) — spinning up instances, managing storage, and controlling costs.
Data Fundamentals
Data is the foundation of all AI systems. Focus on components classified as Data in the SFIA dimension:
Data Sources and Access Learn how to access and query different data sources: relational databases (SQL), NoSQL databases, APIs, and file formats (CSV, JSON, Parquet). Understand the tradeoffs between different storage formats and when to use each.
Data Quality and Exploration Develop a systematic approach to exploring new datasets. Learn to identify data quality issues: missing values, outliers, inconsistencies, and bias. Build habits around exploratory data analysis (EDA) before jumping into modeling.
Data Pipelines (Introduction) Understand the basics of data preprocessing and pipeline construction. Learn to chain transformations together reproducibly. Get familiar with the concept of feature engineering — transforming raw data into inputs that help models learn.

Intermediate Level (Months 7–18)
Goal: Build production-grade AI systems and work across the full ML lifecycle. Move from using pre-trained models to training your own, and from notebooks to production pipelines.
Core Knowledge Areas
Model Development and Training
You are now building and training your own models, not just using pre-trained ones.
Deep Learning Fundamentals Master neural network architectures: feedforward networks, CNNs for images, RNNs/Transformers for sequences. Understand backpropagation, optimization algorithms, and regularization techniques. Build intuition for why models succeed or fail.
Foundation Models and Fine-Tuning Learn how to fine-tune large pre-trained models (LLMs, vision models) for specific tasks. Understand when fine-tuning is appropriate vs. prompt engineering vs. training from scratch. Get hands-on with Hugging Face Transformers and PEFT techniques like LoRA.
Training Infrastructure Master a deep learning framework — PyTorch is the current standard for research and increasingly for production. Learn distributed training for large models. Understand mixed-precision training, gradient checkpointing, and other techniques for efficient training.
Experiment Tracking and Reproducibility Adopt tools for tracking experiments: MLflow, Weights & Biases, or similar. Log hyperparameters, metrics, and artifacts. Build habits that make your work reproducible — by you in six months, and by your teammates.
Deployment and Operations
You need to learn how to take models from development to production and keep them running.
Model Serving Learn how to deploy models as APIs or batch services. Understand serving frameworks: TorchServe, NVIDIA Triton, TensorFlow Serving, or simpler options like FastAPI with model loading. Consider latency, throughput, and cost tradeoffs.
Containerization and Orchestration Master Docker for packaging models and their dependencies. Learn Kubernetes basics for orchestrating deployments. Understand how to build reproducible, portable ML systems.
Monitoring and Drift Detection Learn how to monitor models in production. Track prediction distributions, latency, and error rates. Implement drift detection to identify when model performance degrades because the data has changed. Set up alerting for anomalies.
Evaluation and Testing Build automated evaluation pipelines to test model quality. Understand offline evaluation (held-out test sets) vs. online evaluation (A/B testing). Learn to design evaluation metrics that align with business outcomes.
