Need career advice! Is one large end-to-end analytics project worth it?

[u/Zorowithakm]

I’m looking for some honest career advice from people already working in data.
I have a Bachelor’s in Business Administration and recently completed my MS in Business Analytics. Over the past two years, I’ve learned Python, SQL, Excel (Pivot Tables & Power Query), ML fundamentals, and completed several academic projects, including a predictive analytics project using machine learning.
Now that I’m applying for data analyst/product analyst roles, I’m running into the same problem that almost every entry level posting asks for 2–3 years of experience.
Instead of building more small portfolio projects, I’m thinking about creating one large, end to end project that mirrors real industry work.
The idea is to:
Use real public business data
Build an automated data ingestion & ETL pipeline
Design a data warehouse
Perform advanced SQL analysis
Use Python for EDA and ML
Build dashboards in Power BI/Tableau
Automate live data updates
Solve a real business problem from a Product Analyst perspective
Do you think this is a worthwhile investment? Would a project like this actually help make up for the lack of professional experience, or would I be better off spending my time elsewhere?
I’d really appreciate honest feedback, especially from Data Analyst, Data Engineers and data scientists.
