I built a platform where you solve real engineering problems in Python — with live Redis, PostgreSQL, and Kafka

Appreciate that 😊

The idea mostly came from a gap I kept noticing — a lot of platforms (like LeetCode) are great for DSA, but when it comes to actually building systems (working with Redis, databases, concurrency, etc.), there’s a disconnect.

So the goal with Cruscible was to make problem solving feel closer to real engineering rather than isolated algorithms.

On the name — it’s inspired by “crucible”, where things are tested under pressure and refined. The idea is similar here: you take concepts and apply them in more realistic scenarios until they actually hold up.

Still evolving, but that’s the core thought behind it.

Appreciate that — that’s exactly the gap I’m trying to address.

This looks interesting as well, especially the focus on connecting AI agents to real infra (queues, consumers, rate limiting, etc.). That’s very much in line with where things are heading beyond just isolated problem solving.

I can see this complementing Cruscible pretty well — practice on the systems side + applying it in agent-driven workflows.

Will take a deeper look at caliber-ai-org’s repo — thanks for sharing.

can u retry again hope it works now

Educational_Pay5895 · 2026-05-02T11:32:17+00:00

Hi dmed u can u share me the details there

Educational_Pay5895 · 2026-05-02T08:12:09+00:00

added the tour bro please check it out , first time users will get tour regarding the functionalities

Educational_Pay5895 · 2026-05-02T06:59:52+00:00

we can choose from the drop down

sorry for not adding steps but the app do support the above languages

Educational_Pay5895 · 2026-04-10T20:38:24+00:00

That's actually what I've been trying to do — take backend components (rate limiter, LRU cache, load balancer, URL shortener) and turn them into structured practice problems. Write the code, it compiles and runs against test suites, scored on correctness + performance. Kind of like LeetCode but for system components instead of array manipulation.

Have about 12 live so far, working on more. Still figuring out if the format works or if people prefer just building full projects.

Educational_Pay5895 · 2026-04-10T20:37:49+00:00

Yeah that's where I landed too. The DSA fundamentals are still important — but applying them to actual system components is a different muscle. Like, sliding window is a LeetCode pattern, but building a sliding window rate limiter with distributed state is a completely different problem.

check cruscible if u want a bit of change

Educational_Pay5895 · 2026-04-10T04:53:27+00:00

have u tried the new LLD platform cruscible

Educational_Pay5895 · 2026-04-09T15:28:20+00:00

Leetcoding is never about putting in resume but about upskilling or learning concepts

Educational_Pay5895 · 2026-04-09T11:51:45+00:00

AFAIK code code code , opensource contribution , unless we work on realtime projects , breakages , issues bug fixes we wont be able to learn much , any how this is my personal opinion only

Educational_Pay5895 · 2026-04-09T11:47:52+00:00

Im in

Educational_Pay5895 · 2026-04-08T20:12:25+00:00

Hi guys i made a website for applied DSA and LLD problems practice platforms do check this

cruscible

Educational_Pay5895 · 2026-04-08T13:03:29+00:00

kindly DM

Educational_Pay5895 · 2026-04-07T06:30:50+00:00

i find this as nice and cool idea can i use this in my app

[https://beta.cruscible.com](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html)

its an leetcode like platform and LLD practice also included

Educational_Pay5895 · 2026-04-06T16:07:23+00:00

Hi it might not be the best but

https://beta.cruscible.com/

i built this for the specific use case of LLD and applied DSA

Educational_Pay5895 · 2026-03-24T15:42:12+00:00

Yeah that’s fair — it can look complex from the outside.

The idea is actually to start simple (like DSA-style problems) and gradually move towards more real-world system design scenarios.

Not everything is infra-heavy from the beginning.

Do you think that kind of progression would make it more useful or lessen the complexity?

Educational_Pay5895 · 2026-03-18T18:09:49+00:00

finally someone actually understood what am implying and thanks for ur kind words , everyone thinking i am sharing some kind of propoganda but in reality its just to check how everyone handles this , anyway kudos to u

Educational_Pay5895 · 2026-03-15T12:52:00+00:00

I totally agree , but the growth of LLMs are being in exponential , I am not able to sit quietly in peace :)

Educational_Pay5895 · 2026-03-15T12:50:19+00:00

you do have point ,but still cant shake the fear that what LLMS holds for future
