Thoughts, tutorials, and insights on full-stack development, architecture, and the tools I use.
A practical guide to caching strategies (cache-aside, write-through, write-behind) and the cache invalidation techniques that keep them from serving stale data.
How to choose the right database indexes, avoid the ones that quietly hurt write performance, and scale reads with replicas without introducing replication lag bugs.
How load balancers distribute traffic, why stateless services are what actually makes horizontal scaling work, and how to fix the sticky-session traps that quietly reintroduce state.
Why in-memory sessions break horizontally scaled apps, how to move session state to Redis correctly, and how connection pooling keeps your database from falling over under concurrent load.
A practical comparison of vertical and horizontal scaling — what each actually fixes, where each breaks down, and the architecture changes horizontal scaling requires that most guides skip.
Build practical guardrails for AI agents — prompt injection defenses, destructive-action confirmation, iteration caps, and permission scoping.
Design a well-behaved MCP server — tool granularity, resource vs tool choice, error handling, and avoiding context bloat for the connecting agent.
Test AI agents reliably with task-based eval sets, LLM-as-judge scoring, regression tracking, and why unit tests alone don't catch agent failures.
Set up prompt caching for AI agents to cut both cost and latency — cache breakpoints, TTL tradeoffs, and cache-friendly prompt structuring.
Design reliable tool schemas for LLM agents — naming, descriptions, error handling, and why fewer, clearer tools beat a large tool catalog.
How AI agent memory actually works — working context, session summaries, vector-based long-term memory, and when a file-based store is simpler.
The core architecture patterns behind reliable AI agents in 2026 — the agent loop, tool orchestration, memory layers, and when to use multi-agent.
Build a multi-agent system with the Claude Agent SDK — a coordinator agent that delegates to specialized subagents and aggregates results.

Compare Zustand, Redux Toolkit, Jotai, and React Context for state management in 2026 — bundle size, boilerplate, and when to use each.
Compare Sanity, Keystatic, Contentful, and Payload for a Next.js project — pricing, git-based vs API-based content, and which fits your team size.
Compare Vercel, Netlify, Railway, and Coolify for hosting Next.js apps — pricing, ISR/edge support, cold starts, and which one fits your project.
