Zero-Downtime Deployments: The Complete Playbook
Blue-green, canary, rolling updates, feature flags — every technique explained with real failure stories, rollback strategies, and the database migration patterns that make or break them.

Blue-green, canary, rolling updates, feature flags — every technique explained with real failure stories, rollback strategies, and the database migration patterns that make or break them.
A journey through PostgreSQL internals: the planner, executor, buffer pool, WAL, and MVCC — understanding these makes every query you write more intentional.
NextAuth v5, protecting routes with Middleware, JWT vs session strategies, and pushing auth logic to the Edge for zero-latency protection — all production-proven patterns.
fetch() cache semantics, revalidation strategies, unstable_cache, route segment config — the complete decision tree for choosing how your Next.js app fetches, caches, and revalidates data.
React Server Components are a core feature of modern Next.js applications. In this article, we break down how they work, why they matter, and how they improve performance in full-stack React apps.
Traces, metrics, logs — the three pillars and the fourth nobody talks about: profiling. How to instrument distributed systems so you can debug them when they fail at 3am.
Raft, Paxos, Viewstamped Replication — not as academic exercises but as practical mental models for understanding what your databases actually guarantee.
Why wall clocks lie in distributed systems, how logical clocks restore causality, and the precise guarantees you can and cannot rely on when reasoning about event ordering.
Enforcing strict module contracts in a monorepo: path aliases, project references, barrel files, and why you should treat your shared packages as published APIs.
