About me
I'm Rahul Jaisinghani, a backend engineer turned security specialist, passionate about building secure systems and exploring how AI can transform the future of cybersecurity.
Currently, I serve as a Senior Security Engineer at BrowserStack, where I lead security initiatives across cloud infrastructure, automation, and detection engineering. My day-to-day work spans building secure architecture, driving DevSecOps, and implementing proactive defense strategies across endpoints, networks, and cloud.
My journey began in full-stack development, moved through testing, and gradually evolved into a focused security role — blending hands-on engineering with strategic security thinking. I’ve led and contributed to initiatives around cloud security, web & API security, endpoint defense, IAM hardening, threat modeling, and blue team automation — with occasional red team exploration to stay sharp.
Lately, I’m also exploring how AI/ML can improve detection, automate security response, and strengthen system resilience.
