About me.

SRE with 7+ years of experience building reliable, scalable infrastructure for ML/Data platforms and mission-critical systems. Expert in end-to-end automation — from CI/CD pipelines to ML workflow orchestration in production environments.

Proven track record of reducing downtime by 60% while scaling cloud-native ML systems with 99.9%+ uptime. I bridge the gap between development, operations, and ML engineering.
