CAREER CHANGER · 12–16 WEEK STARTER PLAN
Build your starting foundation
Usually a technical engineering role rather than a first job after a short course. This starter plan is most useful for software engineers, data practitioners, or learners building a longer ML portfolio.
Set a realistic expectation: this plan creates momentum, foundational skills, and initial portfolio evidence. Becoming competitive for a role can take longer depending on your previous experience, practice time, project quality, and local job market.
What you need before starting
- ✓ Comfortable Python programming
- ✓ Probability, statistics, and linear-algebra fundamentals
- ✓ SQL and data preparation
- ✓ Git, testing, and software-engineering basics
- ✓ Experience training at least one supervised-learning model
Focused foundations
Learn only the programming, data, and AI concepts needed to begin.
- Week 1Learn focused Python, Git, and command-line basics for Machine Learning Engineer
- Week 2Understand Calculus and linear algebra and Probability
- Week 3Learn JSON, APIs, data handling, and how AI systems are evaluated
- Week 4Complete small exercises and explain one AI workflow in your own words
