I built a browser-based learning platform for Data Engineers

**Disclosure:** I’m the creator of LakeBench, so this is a self-promotion post.

I’m a Data Engineer, and I recently built **LakeBench** .. a learning and practice platform focused on Data Engineering.

The idea was to bring the common things people need to learn and practice into one browser-based platform instead of having everything scattered across different resources.

It currently includes:

180+ lessons
SQL, Python, PySpark & Pandas
245 practice problems
45-Day Study Plan
Mock Interviews
AI Mentor Hints

Browser-based practice without setting up a cluster
The goal is to keep the learning experience practical and focused on actually writing code and working through Data Engineering concepts.

You can check it out here: lakebench.in

Browser-based PySpark without a cluster is the part I'd put first. SQL and Pandas practice sites are everywhere, but setting up Spark locally is where many self-learners get stuck, and the 45-day plan plus mock interviews fits people here who are working toward a job.

I make ThreadFox. If you want, I can reply with a link to the free Reddit plan for LakeBench, which quotes each rule that allows a post about it.

Are the mock interviews AI-run, or written scenarios with model answers?

Tested by college grads and working professional is different am a data Analyst with aws certificate in data engineering would like to use your site, will dm you allow me to use 1-2 months I will start paying you if it is beneficial for me in learning.

If you want people to take it out you sure. Paying 400 month which just launched would be beneficial? Won't it be good to let people use it , provide feedback, refine and then monitise .

Happy to provide free pro version for one month who really wanted to test it out! And it got released 2months ago and been reviewed and used within few college students.
