Anup Haldar's Blog
I write about the things I actually build and learn along the way from using Claude Code for development to TypeScript, React, and full stack patterns I use in real projects. I also share the performance improvements and small details that help make websites faster. No filler, just things I've found useful.
Chat apps, coding agents, autocomplete, AI search: which kind of AI tool fits which job, common mistakes, and how to compare tools on your own code.
Cursor is a VS Code fork built around Tab completion; Claude Code is a terminal-native agent. How they actually differ, and when to reach for each.
How this Next.js blog's sitemap, robots.txt, llms.txt and JSON-LD are wired up, plus two Search Console and PageSpeed warnings that weren't bugs.
A hands-on guide to Claude Code: install it, run your first session, and use plan mode, CLAUDE.md, subagents, hooks and headless mode on real projects.
I am Anup Haldar, a full stack developer in Uttarakhand, India. I have been building web applications for the past three years, mainly with TypeScript, React, Next.js, NestJS, and PostgreSQL. Outside of work, I build and ship side projects like Ridenomics and Free Text Cleaner. This site is where I share what I build, learn, and work on along the way.
