Becoming a data science developer involves a series of steps and learning milestones to build the necessary skills and knowledge. Data science is a vast and rapidly evolving field that needs to be updated and keep learning. Here I am sharing a general roadmap to get started:
There are four prerequisites for becoming a data science developer Mathematics, Programming concepts, and Data manipulation and manipulation.
Mathematics: This is the first prerequisite you must have. Developing a strong foundation in mathematics, including linear algebra, calculus, probability, and statistics is a must.
Programming: To start a career in Data Science, you must have knowledge of programming languages. You can learn Python or R, because both are commonly used programming languages in data science.
Data manipulation: Learn data manipulation libraries like Pandas (Python) or data.table (R).
Visualization: Start learning data visualization tools and libraries like Matplotlib, Seaborn, ggplot2, or Plotly.
Start learning fundamental concepts like data types, data cleaning, and exploratory data analysis (EDA).
and also understand basic statistical concepts and hypothesis testing.
Learning machine learning algorithms such as regression, classification, clustering, and dimensionality reduction is vital if you are looking career in Data science. So start learning how to use machine learning libraries such as Scikit-Learn (Python) or Caret (R).
Data Preprocessing is another vital step you must follow. Start learning data preprocessing techniques like feature scaling, encoding categorical data, and handling missing values.
Explore and start learning advanced Machine Learning topics such as ensemble methods, deep learning, and natural language processing (NLP). Also, study the popular deep learning frameworks like TensorFlow or PyTorch.
Start learning how to evaluate and validate machine learning models using metrics like accuracy, precision, recall, and cross-validation.
Learning big data technologies (Apache Hadoop and Apache Spark) is one of the most important steps you must follow. This step involves handling large datasets.
Start learning the database concept and database programming languages like SQL and NoSQL.
Master yourself in data visualization tools like Tableau, Power BI, or D3.js to effectively communicate insights from your data.
Learn how version control systems like Git and Collaborate.
Start working on real-world projects and applying your learning. Also, build a portfolio to showcase your skills to potential employers.
Study more Tutorials related to Data science and machine learning. Also, you can Enroll in a Data science certification to enhance your skills.
Data science is one of the fastest-growing and evolving fields. So you must update yourself with the latest trends, tools, and research.
Stay connected with your friends working in the same field, data scientists, and attend seminars, and online discussion forums.
