India

Message

At RapiFuzz PVT LTD, I spearheaded the development and launch of enterprise security products and architected secure CI/CD pipelines and network infrastructure. I also oversee secure AI/LLM infrastructure across company products.

As Technical Security Lead, I’m responsible for production deployments, hotfix resolution, and system stability. I’ve also supported government deployments by ensuring product security compliance with GIGW standards and GRC requirements.

Earlier at RapiFuzz, I conducted VAPT and manual secure code reviews across in-house products, built custom security tools, and managed OpenNebula and OpenStack cloud infrastructure. At RamoGnee Technologies PVT LTD, I contributed to enterprise product development and tested IoT firmware in virtual environments.

I self-developed Nexard, a cyber surface intelligence platform, and Pramana, a security layer for AI agents. My vulnerability research includes 10+ disclosed CVEs, and I’ve delivered cybersecurity training at BITS Pilani.
