Long-form deep dives on how software works under the hood: system design, databases, architecture and the web. Every article is available in English and Bangla.
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.
An in-depth technical guide on database execution plans, B-Tree index range scans, the O(N) bottleneck of deep offsets, and production-grade opaque cursor architecture.
A complete deep dive guide on how database connection pools work, why systems crash under heavy traffic, and how to design production scale connection management architectures.
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, under-the-hood analysis of Object-Oriented Programming vs Functional Programming for resolving state management crises and making scalable architectural decisions.
Explore how RFC 10008 solves the 16-year-old HTTP query limitation. This comprehensive handbook covers framework-agnostic implementation principles, a reference FastAPI backend, Uvicorn parser gotchas, client-side fetch quirks, caching realities, security concerns, and production adoption status.
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 step-by-step developer guide on using Cloudflare WAF custom rules and cf.client.bot to block AI web scrapers while preventing Google Search Console 403 errors.
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 comprehensive engineering deep dive into how Google's 2017 Transformer architecture powers modern generative AI, why Google missed the first-mover advantage, and how OpenAI captured the market.
