Crack your next high-level system design and backend interview with "Crack It!"
"Crack It!" is a comprehensive, interactive guide designed for senior engineers, architects, and backend developers preparing for interviews at top-tier tech firms and FinTech leaders.
We don't just teach theory. We dive deep into real-world scenarios—like UPI payment systems at PayZest or high-frequency trading at PrimeBroker—to show you how architecture decisions impact production at scale.
WHAT’S INSIDE?
🚀 Deep-Dive Topics:
•
Apache Kafka: Master Zero Data Loss, Strict Ordering, and Poison Pill strategies.
•
Java 21: Modern features like Virtual Threads (Project Loom), Record Patterns, and Pattern Matching.
•
Spring Boot: Microservices architecture, REST optimization, and production-grade configurations.
•
Kubernetes (K8s): Container orchestration, scaling, and reliability.
•
Databases: PL/SQL mastery, performance tuning, and distributed data consistency.
💡 Real-World Scenarios: Learn how to solve complex problems like:
•
How to handle ₹50,000 RTGS transfers without losing data when a broker crashes.
•
Preventing illegal overdrafts in brokerage accounts using strict partition ordering.
•
Building resilient enrichment services that handle "Poison Pill" malformed messages using DLQs.
📖 Interview-Ready Content:
•
Curated Q&A: Over 100+ technical interview questions categorized by topic.
•
Expert Answers: Detailed explanations that focus on "Why" and "Trade-offs," not just "How."
•
Scenario-Based Learning: Practice with the exact type of architecture questions asked by companies like Google, Meta, and top FinTechs.
🛠️ Technical Edge:
•
Clean UI/UX: Dark-themed, distraction-free reading experience.
