About
HackerHeap is for working developers who want to actually build with AI agents — not just read about them.
Every video and post here ships a runnable repo. We dig into Claude Code, MCP servers, agent automation, AI-native workflows, and the honest comparisons between Claude, Cursor, Codex, and Windsurf. No hype, no fluff, no AI doom — just an engineer showing the build.
The author
Hi, I am Raj. I have been writing software professionally for over a decade — Java, Spring, microservices, distributed systems. Started HackerHeap in 2019 as a coding-tutorials channel and ran it for a couple of years. The world changed; the channel went quiet. In 2026 I am rebuilding it for the AI-native era — same audience, same code-first tone, new toolkit.
