This is a learning roadmap for anyone who want to be a ML Engineer. I created it from perspective of full-stack developer with no experience with ML and Python. Goals I had in mind when I created this roadmap:
---
## Level 0: Python & math essentials *<-- I am here*
**Goal:** Learn just enough Python and math to understand and write ML code.
### Topics
- Python basics (variables, functions, loops, classes, data structures, testing)
- NumPy
- pandas
- Matplotlib & Seaborn for visualization
- Basic linear algebra, probability, statistics
### Mini-projects
- Jupyter Notebook that shows Python basics: [Notes from the Python Tutorial](Python%20Tutorial%20Notes.ipynb) β
ππ―
- [Basic Python Programs for learning purposes](Basic%20Python%20Programs%20for%20learning%20purposes.md)
- Text Analyzer β show list comprehensions, lambda functions, text operations
- Task Manager CLI app β mix object-oriented and procedural styles
- Backup Automation Script β work with files and directories
- Calculator for stats β demonstrate NumPy and descriptive statistics
- Weather App β connect to a weather API and show JSON parsing
- CSV/PDF Report Generator β automate report formatting
- Note Manager GUI β use Tkinter for building a visual tool
- Random Test Data Generator β generate data for testing other projects
### Resources
- [Python Tutorial](https://docs.python.org/3/tutorial/index.html) β

## Level 1: your first ML project
**Goal:** Build a full beginner ML pipeline using a structured dataset.
### Topics
- What is ML? Types of learning
- ML pipeline: data β model β prediction
- Scikit-learn: train/test split, fit, predict
- Evaluation: accuracy, confusion matrix
### Mini-projects
- Predict flower species (Iris)
- Classify Titanic survivors
- Build a spam email detector
- Automate markdown summaries from email text (custom dataset)
- Use CLI tool to classify text (combine ML + CLI app)
---
## Level 2: Data Understanding & Feature Engineering
**Goal:** Learn to explore and clean datasets, and create useful features.
### Topics
- Exploratory Data Analysis (EDA)
- Feature types, missing values, outliers
- Encoding categorical variables
- Normalization, standardization
### Mini-projects
- Clean and analyze a housing dataset
- Feature engineer from scraped product prices
- Analyze financial data with pandas and visualize trends
- Web scraper for products β collect training data yourself
---
## Level 3: Algorithms and models
**Goal:** Understand how different ML algorithms work and when to use them.
### Topics
- Supervised: Logistic regression, Decision Trees, k-NN, SVM
- Unsupervised: Clustering (k-means), Dimensionality Reduction
- Model selection, bias/variance tradeoff
### Mini-projects
- Compare models (logistic vs. tree vs. SVM)
- Tune a Decision Tree and explain feature splits
- Cluster product prices and show in 2D plot
- Create a template engine with test case generator to explore logic programming
---
## Level 4: Model tuning & evaluation
**Goal:** Learn how to optimize your models and avoid overfitting.
### Topics
- Cross-validation
- Grid search and random search
- ROC curves, AUC, F1 score
- Overfitting and underfitting detection
### Mini-projects
- Tune spam detector with grid search
- Build a multithreaded file downloader that logs performance
- Apply window functions to time series of sensor or stock data
- Create a basic unit test framework to wrap your pipelines
---
## Level 5: Build your own ML tool
**Goal:** Apply ML to a real problem with a full end-to-end solution.
### Topics
- Problem scoping and framing
- Data collection and cleaning
- Deployment basics (e.g. Flask, Streamlit)
- Communicating results and business value
### Mini-projects
- Streamlit app: sentiment analyzer or price predictor
- Flask API for ML model serving
- Django mini blog with prediction plugin
- AI-powered chatbot with basic NLP features
---
## Level 6: Deep Learning Foundations
**Goal:** Dive into neural networks and build intuition for deep models.
### Topics
- Perceptron, activation functions, backpropagation
- Keras/TensorFlow for building neural networks
- CNNs and RNNs intro
### Mini-projects
- Digit classifier with MNIST
- Image classifier for product categories
- RNN-based sentiment analysis
- Intro chatbot with sequence modeling
- Experiment with simple AI modules in games
---
### Level 7: Real-World ML & next steps
**Goal:** Expand your skills and apply ML to domains of interest.
### Topics
- Transfer learning, pre-trained models
- ML in production (monitoring, updating models)
- Ethics and bias in ML
- Optional: NLP, recommender systems, time series
### Mini-projects
- Reuse pretrained models from Hugging Face or TensorFlow Hub
- Build a monitoring system for API predictions
