Building scalable systems & agents.

Hi, I'm Mehul Arora. I build production-grade web applications, highly concurrent systems, and AI-driven agents.

About Me

I am a full-stack developer based in India, obsessed with building high-performance software.

My journey started with a fascination for how systems scale. I don't just build UI; I architect complete solutions—from robust Node.js backends and real-time WebSockets to fluid, beautiful React frontends.

I recently built a system handling 1 Million real-time checkboxes using Redis, and an AI Agent (Arbiter) that cross-validates LLM responses for accuracy.

When I'm not coding, I'm usually diving into system design patterns, playing video games, or making content about software engineering on YouTube.

How I Made My Own Persona Bot

In this video I explain how I approached building a Persona Bot that talks exactly like Hitesh Sir and Piyush Sir. I also discuss why I used Manual GuardRails over OpenAI Agentic SDK's built-in guardrails.
