What I'm looking for

I am looking for a senior role where I can drive scalable solutions and continuous improvement in a dynamic environment.

I am a visionary DevOps leader with over 9 years of end-to-end cloud infrastructure expertise. I have successfully built, scaled, and optimized distributed systems for over 30 million users, ensuring high availability and performance. My experience includes leading the migration of mission-critical services to containerized architectures, significantly improving deployment velocity and reducing downtimes.

Throughout my career, I have demonstrated a strong ability to drive cross-functional collaboration and lead high-performing teams. I have pioneered real-time ETL pipelines and implemented robust monitoring systems that drastically cut Mean Time to Recovery (MTTR). My passion for innovation is reflected in my development of AI-powered applications and automated content delivery systems, showcasing my hands-on capabilities in system design and emerging technologies.
