I want to become a digital systems optimizer e Ai System designer, how can I do? it s easy to found job?

Hi everyone,

I'm 34 and currently working in healthcare, but I'm feeling pretty unfulfilled and seriously considering a career change into the digital/tech world. Two roles that caught my eye are **Digital Systems Optimizer** and **AI Systems Designer** — I'd love to hear from anyone who knows these paths.

My main questions:

**1. Online courses vs. a CS degree?**

Do I really need a full computer science degree, or can solid online courses (even paid ones) be enough to break into this field? I've been browsing Coursera and CareerFoundry but I'm getting mixed signals — some people swear by them, others say they're not worth it for landing a job.

**2. Does this learning roadmap make sense?**

I've drafted a rough plan for myself:

- Data Analysis

- Machine Learning (Python + SQL)

- AI Tools

Does this order make sense? Is anything missing or should I reorder it? I know hands-on practice matters more than certificates — any advice on how to build real projects along the way?

**3. Your personal journey**

If you've made a similar transition (especially from a non-tech background), I'd really appreciate hearing what worked for you — courses, projects, timelines, anything.

Thanks in advance to anyone who takes the time to reply. It really means a lot! 🙏
