• Apply supervised and unsupervised learning techniques to real‑world problems.
• Good understanding of Regression, Classification, and Clustering algorithms. Understand model evaluation techniques such as cross‑validation, ROC‑AUC, Precision, Recall, and F1‑score.
• Perform feature engineering, feature selection, data preprocessing, normalization, and scaling.
• Understand model training, validation, hyperparameter tuning, and performance optimization.
• Ability to analyze model results and identify opportunities for improvement.

2. Data Processing & Analysis

• Strong practical experience with Pandas and NumPy.
• Ability to clean, transform, analyze, and prepare raw datasets for machine learning.
• Experience working with structured datasets and building reusable data‑processing workflows.
• Basic understanding of data quality, missing values, outliers, normalization, and feature preparation.
• Polars is optional.
• Experience with time‑series data is optional/preferred.

3. Deep Learning & Advanced ML (Preferred)

• Basic practical understanding of neural networks and deep learning concepts.
• Hands‑on experience with CNN, RNN, or LSTM is preferred but not mandatory.
• Ability to understand and work with existing deep learning models.
• Experience with time‑series modeling, signal processing, peak/event detection, or waveform data is optional.
• Experience with scientific or instrument‑generated datasets, including mass spectrometry data, is a plus but not mandatory.

4. Model Deployment & Software Engineering

• Develop clean, modular, and production‑ready Python code.
• Basic hands‑on experience with FastAPI, Flask, or Django for serving ML models is preferred.
• Understand how to expose trained models through APIs.
• Experience with Git and collaborative software development workflows.
• Ability to write basic unit tests and maintain code quality.
• Basic Docker knowledge is preferred.

5. MLOps (Optional)

• Basic understanding of the machine learning lifecycle.
• Exposure to MLflow, DVC, or similar experiment/model tracking tools is a plus.
• Basic understanding of model monitoring and model drift is a plus.
• Basic understanding of CI/CD pipelines for ML deployment is preferred but not mandatory.
• Experience deploying ML workflows using Docker is a plus.
• Basic to intermediate experience with PostgreSQL or MySQL.
