Hello, I'mDharsan Dhanaraj
Senior AWS-Certified Cloud Technical Support & Site Reliability Engineer with 9+ years building and defending mission-critical airline platforms. I make systems reliable, incidents shorter, and operations smarter with AI.
The Operator Behind the Uptime
I've spent 9+ years in airline IT and cloud operations, working at the intersection of reliability, automation, and AI. From leading 24/7 global incident management for Singapore Airlines to building LLM-powered intelligent operations, I focus on one thing: making sure the systems people rely on actually work.
What drives me is solving high-impact problems under pressure. I'm now looking to bring that mindset to a team that values problem-solving, reliability, and operational ownership on a global scale. Currently pursuing my Generative AI Developer Professional certification.
