How to Gain Hands-on Experience in DE Without High Cloud Costs?

Hi folks, I have 8 months of experience in Data Engineering (ETL with ODI 12C) and want to work on DE projects. However, cloud clusters are expensive, and platforms like Databricks/Snowflake offer only a 14-day free trial. In contrast, web development projects have zero cost.

As a fresher, how can I gain hands-on experience with DE frameworks without incurring high cloud costs? How did you tackle this challenge?
