Data is a powerful tool for decision-making in all spheres of life. Modern businesses collect data on almost everything associated with their business, and hope to use this data to get insights that will create more value for their business. However, to make sense out of such unstructured data, they need data analysts who can structure the data in their databases, and extract it whenever there is need for analysis. I have packaged this course to take you through the whole journey of a data analyst. You will learn about databases, querying databases using SQL, modeling the data using Python, and visualizing using Power BI and Tableau.

Learn Python, SQL, machine learning and AI from someone who builds these systems in production every day. I am a Lead Data and Machine Learning Engineer based in Berlin, with 9 years at Amazon, Delivery Hero, Goldman Sachs and now Orion S.A., and I have been teaching here since 2021. WHO THIS CLASS IS FOR Complete beginners who want to learn programming properly, from zero, with no assumptions. University and bootcamp students stuck on Python, SQL, algorithms or a machine learning assignment. Working professionals moving into data engineering, data science or AI roles. Candidates preparing for technical interviews at product and tech companies. WHAT WE CAN COVER We pick the path together based on your goal. Options include: Python fundamentals, clean code and object oriented programming Data structures and algorithms, with the reasoning behind each choice SQL and databases, from joins and window functions to designing a warehouse Pandas, NumPy, data cleaning and exploratory analysis Machine learning: regression, classification, trees, model evaluation, and the quiet mistakes that ruin a model Deep learning and natural language processing foundations Generative AI in practice: RAG, embeddings, vector databases, LangChain, OpenAI and AWS Bedrock Data engineering on AWS: S3, Glue, Redshift, SageMaker, Airflow, Spark and dbt Interview preparation, including mock interviews and system design for data roles HOW LESSONS WORK In the first lesson we work out where you are and what you actually want to reach, and I map a path to it. After that every session is hands on. You write code, I review it live, and I explain the reasoning rather than just handing you the answer. You finish each lesson with something that works: a script, a notebook, a query, a pipeline, or an answer you could confidently give in an interview. Between lessons you get exercises and a project that grows week by week, so you end up with something real to show an employer. WHY LEARN WITH ME I teach what I do. The examples come from real systems that serve real users, not from textbook datasets. I will also tell you honestly when an approach will not hold up in production, which is the main reason to learn from a practitioner rather than a video course. My open source guide for machine learning interviews has more than 700 stars on GitHub and is used by candidates preparing for data and ML roles. PRACTICAL DETAILS Lessons are in English, online via webcam, and I am comfortable working across time zones. Suitable for teenagers from 14 and for adults. No prior experience is needed for the beginner track.
