Full-time timeline
01
01

Python & Math Foundations

3–4 weeks

The technical bedrock of ML engineering — Python performance patterns, linear algebra for neural nets, and the probability/statistics that make model decisions principled rather than arbitrary.

02
02

Classical Machine Learning

4–6 weeks

The fundamentals every ML engineer must own — scikit-learn pipelines, gradient boosting, and model evaluation. These algorithms dominate production tabular ML in 2026.

03
03

Deep Learning (PyTorch)

6–8 weeks

Build real intuition for how neural networks learn — from scratch training loops to transformers. PyTorch is the 2026 production and research standard.

MLOps & Experimentation

3–4 weeks

Transform ad-hoc model training into reproducible, versioned, production-ready engineering — experiment tracking, pipeline automation, and model governance.

05
05

Cloud & Model Serving

4–5 weeks

From trained model to production endpoint — Docker, FastAPI, Kubernetes, and managed cloud ML platforms for scalable, monitored inference.

06

LLM Fine-Tuning & RAG

4–5 weeks

Adapt foundation models to domain-specific tasks with LoRA/QLoRA, build production RAG pipelines, and orchestrate multi-step LLM workflows with LangGraph.

07
07

Inference Optimisation & Scale

3–4 weeks

The skills that separate ML engineers who can deploy prototypes from those who can run production AI economically — quantisation, distributed training, and drift monitoring.

Portfolio & Career

2–3 weeks

Build the portfolio that gets you hired — production-thinking projects, ML system design interview prep, and the GitHub profile that makes recruiters reach out.
