HE CRACKED ML INTERVIEWS AT TOP COMPANIES WITH JUST 80 LEETCODE PROBLEMS
Grinding 500+ questions in panic… he chose a system instead
He focused only on the patterns that actually show up in ml rounds trees, graphs, dynamic programming, binary search, sliding window... that's it
but the real secret wasn't the list
it was his rule: solve every non-trivial medium 3 times
first time you struggle... that's fine second time you start seeing the pattern
third time you solve it in under 10 minutes
he tracked every session how long it took, how many attempts until the problems felt automatic
result...? offers from snapchat, coupang & stitchfix
not because he knew everything because he knew the right things deeply
the full list is free on github

10 proyectos backend que te pondrán por delante del 90% de los devs:
0. Servidor HTTP desde sockets puros
1. Clon completo de Redis
2. Clon de Kafka (message broker)
3. Reverse Proxy / Load Balancer
4. Rate Limiter (Token Bucket + Sliding Window)
5. Scheduler de tareas CRON
6. Broker de WebSockets
7. Caché distribuida con consistent hashing
8. Mini search engine (con inverted index)
9. Acortador de URLs con analíticas y tracking

Quick Linux Tip:
When a process is hanging, and you don't want to kill it, use strace to see exactly what system call it's stuck on in real time.
$ strace -p <PID> -e trace=read,write,open
Used heavily in production debugging - no code changes, no restart needed. Shows file descriptors, network calls, and blocked I/O live.

❗️ Love this new YouTube genre where a randomly laid-off Atlassian engineer with 8 years at the company just dropped a full technical breakdown of the entire place.
Unpopular opinion:
Studying system design from just YouTube videos and blogs is why most engineers with 5+ years of experience are still earning much LESS
Here's the brutal truth about why and what actually works. 👇
