A deep dive into Redis source code to understand how RDB snapshots and AOF logging keep your data safe. Learn about fork(), copy-on-write, fsync strategies, and the AOF rewrite dual-buffer trick.

Explore how Redis actually works by reading its C source code on GitHub. Learn about robj, incremental rehashing, the event loop, integer encoding, and adaptive list storage — the real internals that make Redis so fast.

Master Spring Boot performance optimization with JVM profiling, Actuator metrics, database tuning, HTTP caching, GC optimization, and startup acceleration. A complete guide to building high-performance Java applications with measurable improvements.

Go beyond unit and integration tests. Learn consumer-driven contract testing with Spring Cloud Contract, API compatibility verification, performance testing with Gatling, load testing strategies, and advanced testing patterns for production-ready Spring Boot applications.

Master load balancing fundamentals: algorithms (Round Robin, Least Connections, IP Hash), Layer 4 vs Layer 7, health checks, session persistence, SSL termination, and implementation with Nginx, HAProxy, and cloud providers.

Master JPA performance optimization in Spring Boot. Learn to detect and fix N+1 query problems, optimize fetch strategies, use projections, batch operations, and write efficient JPQL and native queries.

Master Redis fundamentals from scratch. Learn data structures, commands, persistence, pub/sub, and real-world use cases. Perfect foundation before implementing Redis caching in your applications.

Master Spring Boot caching with Redis for high-performance applications. Learn Spring Cache abstraction, Redis configuration, cache strategies, TTL management, and distributed caching patterns with hands-on examples.

Learn asynchronous programming in Python with asyncio, event loops, coroutines, and async/await. Build high-performance concurrent applications with modern Python.
