Introduction to Big Data Tools
Learn why big data processing exists, how distributed computing works, and why tools like Apache Spark handle the heavy lifting so you can focus on business logic.
Blogs
All the topics I've covered. I write about React, Next.js, TypeScript, databases, AI/ML, cloud deployment, performance optimization, and system design.
Bloom Filters
Learn how Bloom filters work: a probabilistic data structure that tells you with 100% certainty when something doesn't exist. Understand hash functions, bit arrays, false positives, and real-world use cases like recommendation engines and web crawlers.
Consistent Hashing
Learn how consistent hashing solves the data ownership problem in distributed systems. Understand hash-based routing, the ring abstraction, and how to scale up and down with minimal data movement.
Communication Protocols
Understand how clients and servers communicate over the network. TCP fundamentals, HTTP, WebSockets, Server-Sent Events, and API paradigms like REST, GraphQL, gRPC, and tRPC.
High Availability
Learn how to build resilient systems through data redundancy, automatic failover, and leader election. Understand backup strategies, database replication, disaster recovery patterns, and how leader election enables zero-downtime auto-recovery.
Circuit Breakers
Learn how circuit breakers prevent cascading failures in distributed systems. Understand why services fail together, how to implement circuit breakers, and practical patterns for building resilient microservices.
Load Balancers
Learn how load balancers enable horizontal scalability by distributing traffic across multiple servers. Understand load balancing algorithms, request flow, and key advantages for building resilient systems.
Async Processing with Message Queues, Streams, and Pub/Sub
Learn when and why to use asynchronous processing. Understand message queues, streams, and real-time Pub/Sub for building scalable, decoupled systems.
Caching
Understand caching fundamentals: what it is, why it matters, and how to use it. Learn about cache architecture, key-value access patterns, and real-world examples with Redis and Memcached.
Understanding Database Scaling and Sharding Patterns
Master database scaling from vertical to horizontal scaling, read replicas, sharding strategies, and partitioning techniques. Learn when to use synchronous vs asynchronous replication and how to choose the right shard key.
Database Transaction Internals
Deep dive into how database transactions work under the hood. Understand ACID properties, isolation levels, locking mechanisms, and implementation across PostgreSQL, MySQL, and MongoDB
