How to survive in hyderabad in 4.5 lpa package 🥲

As a backend engineer: Mandatory skills that separate juniors from seniors.. • SOLID principles (write code that doesn't rot) • Multithreading & concurrency (threads, async, locks, deadlocks) • Immutability (avoid bugs from shared mutable state) • Streaming & messaging (Kafka, RabbitMQ, queues, pub/sub) • Caching strategies (Redis patterns, invalidation, eviction) • Security fundamentals (SSL/TLS, JWT pitfalls, OAuth2 flows) • Key design patterns (Factory, Decorator, Singleton, Observer) • TDD (test-first mindset)

Good night

Elastic Load Balancing : spreads incoming traffic across EC2 instances, containers, and IPs in multiple Availability Zones. It monitors target health and routes requests only to healthy resources, ensuring high availability and fault tolerance.

Load balancers use smart algorithms to share traffic : • Round Robin – requests are assigned one by one • Least Connections – traffic goes to the least busy server • IP Hash – same user reaches the same server • Weighted – stronger servers handle more load

A Load Balancer is the traffic cop of the internet It spreads requests across servers ⚖️ Prevents overload 💥 Improves speed ⚡ Boosts reliability 🛡️ That’s how apps stay smooth even when the crowd rushes in

Horizontal scaling = grow out, not up Add more servers ➕ Share the traffic 🔁 Handle more users 👥 Stay fast ⚡ Stay reliable 🛡️ That’s how modern apps survive massive demand without breaking #systemdesign

Literally whenever I feel bored :)

Start preparation for upcoming bank exams :)

Let's see who is really smart?

Rahul joined TCS. CTC: ₹3.36 LPA In-hand: ~₹24k/month 2 years went by. ₹3.36 → ₹3.9 → ₹4.6 LPA Same pattern: - support tickets - client calls - “KT” and “status updates” - zero ownership Then he made one move that changed everything. He took a break: 5 months. Daily routine: - 6 hrs/day DSA (cf + LC) - 2 hrs CS fundamentals (OS/DBMS/CN) - 1 hr writing: notes + revision + mock interviews Total: ~1,300 hours of focused prep. He came back and joined a startup. Offer: ₹18 LPA Jump: 4x But the real shift wasn’t money. It was all about how he worked. In 6 months, he shipped: - cut one hot API from 900ms p95 → 140ms p95 - reduced DB CPU by 35% with proper indexes + query rewrite - added caching + idempotency keys, dropped duplicate writes by 90% - set up alerts + dashboards, incidents went from 3/week → 1/week - owned on-call, wrote postmortems, fixed root causes instead of patching symptoms In 18 months, his scope grew: - led a migration that reduced cloud bill by ₹6–8 lakh/month - designed a queue-based pipeline doing 1M+ events/day - ran load tests, set SLOs, and made deployments boring Then he interviewed again. Timeline: TCS (2 yrs) → Break (5 months) → Startup (2 yrs) → Google At Google: Role: Lead-level engineer (scope-based, not “title-based”) Total comp: ₹1Cr+ band (depending on level/location) Rahul didn’t “get lucky.” He just used numbers that compound: 5 months of prep → 4x salary jump → 2 years of ownership → 1 career tier up. That’s the difference. Experience grows with time. Net worth grows with strategy.
