About Me

Hello! My name is Rahul, and I enjoy building things that thrive on the internet. I’ve always been driven by a curiosity to create, optimize, and innovate. That curiosity led me to explore cloud services, email infrastructure and building systems that scale and stay resilient.

I’m currently a CloudOps and Email Deliverability Engineer at Cvent, where I focus on building scalable infrastructure, ensuring high email deliverability, and improving operational efficiency through automation and cloud technologies. I enjoy building systems that are not only functional but also resilient and efficient.

When I’m not architecting cloud infrastructure or fine-tuning email systems, you’ll often find me exploring emerging tech trends or experimenting with the latest in AI.

Here are a few technologies I've been working with recently:
