Articles about system design.
A complete engineering guide on why exactly-once delivery is mathematically impossible at the network level, and how to build effectively-once architectures in production using idempotency, transactional outbox, and inbox patterns.
A deep architectural dive into why standard Redis locks fail in distributed systems, covering lease expiries, paused processes, and how database-level fencing tokens guarantee absolute correctness.
An in-depth engineering handbook breaking down QR code structural layouts, optical mechanics, Reed-Solomon error correction math, and high-throughput deployment patterns using Node.js and React.
A practical engineering guide to handling distributed transactions and data consistency when moving from monoliths to microservices. Learn the mechanics of dual-write anti-patterns, Change Data Capture, Write-Ahead Logging, and idempotent consumers.
A production engineering guide explaining why Two-Phase Commit is dead in microservice architectures and how Distributed Sagas work. Explore the low-level mechanics of orchestration, choreography, Write-Ahead Log replay, and concurrency anomalies.
A complete engineering roadmap detailing how to scale a startup MVP to 10 million concurrent users, covering distributed databases, caching strategies, and microservice design patterns.
A deep architectural breakdown of how high-throughput chat applications clear conversations at Big-O(1) storage complexity using timestamp-based view filtering and metadata pointers instead of database-level hard deletes.
