Within past 2 months grinding on codechef, solved 1500+ easy problems.. ik I am doing wrong, I am looking for guidance.. also I am looking to enter into data related field, like DA, or DS or ML engineering.. All I know is beginner-intermediate level python.

@SirAlexanderrr Interested

[Aman Panwar @_panwar_aman_]

@groldrush I have 2 but want 3..

@Surendar__05 Notepad lol, when I was in class 3

If I had to learn Backend Development again in 2026,

I'd focus on only these 10 topics:

1. API Design (REST/GraphQL)
2. SQL & Database Design
3. Indexing & Query Optimization
4. Caching (Redis)
5. Authentication & Authorization
6. Message Queues (Kafka/RabbitMQ)
7. System Design Fundamentals
8. Concurrency & Transactions
9. Docker & Deployment
10. Monitoring & Observability

Master these 10.

You'll know more backend engineering than most developers chasing every new framework.

@Hiteshdotcom Too tight such that, even if a person(my dad) hasn't use Facebook account for 4 years haven't posted anything.. and suddenly got email that his Facebook ID has been banned for violation of policy, policy for not posting anything(sarcasm). Lol.

[Aman Panwar @_panwar_aman_]

@Hiteshdotcom Hey @Hiteshdotcom, I know it's really off topic rn, but can you answer why so many peoples accounts from Instagram and Facebook are getting banned by Meta, for no reason, like is it AI algo glitch or there "security" is getting too tight?

[Aman Panwar @_panwar_aman_]

@finkd Help me create a Facebook account or sell your company to @elonmusk, he do definitely make it better.

Want to become a Python Developer?

Know these first:

✅ Python basics
✅ Functions
✅ OOP
✅ File handling
✅ APIs
✅ SQL
✅ Git + GitHub
✅ Virtual environments
✅ Error handling
✅ Basic testing
✅ Flask/FastAPI
✅ Deployment basics

Python dev isn’t just writing scripts.

It’s building clean, useful apps that solve real problems.

Leetcode graph prep list I keep (covers 80% of interviews):

1. BFS/DFS on adjacency list: 200, 547, 733, 841
2. Grid BFS/DFS: 994, 1020, 130, 417
3. Topo sort (Kahn/DFS): 207, 210, 269
4. Shortest path: 787 (Dijkstra-ish), 743 (Dijkstra), 127 (BFS), 542 (multi-source)
5. Union-Find: 684, 1319, 721, 990
6. Bipartite: 785, 886
7. MST: 1584 (Prim/Kruskal)

Do these, but also write down: “graph model + visited rules + complexity”. That’s what interviewers actually probe.

How to use this list?
- These numbers are Leetcode problem numbers
- Do 3 patterns at a time, not all 30 together.
- For each pattern, solve the first 2 to understand the idea, the next 2 to get repetition, and the last 2 to stretch yourself.
- After every pattern, write one reusable template from memory.
- Do not just “solve and move on.” Ask: what signal in the question pointed to this pattern?
- If you get stuck, revisit the same pattern after 3 to 4 days. Pattern recognition is built by spacing, not cramming.

Python is becoming a REQUIRED skill in 2026.

Here’s how I’d master it in 12 months:
