ABOUT ME

The engineer behind the infra

I'm Alan Sarang M A, an AWS Certified Cloud & DevOps Engineer based in Bengaluru, Karnataka. Passionate about building reliable infrastructure, automating toil, and keeping systems observable and cost-efficient.

Currently interning at TechBrein IT Solutions in Calicut, where I provision and manage EC2 infrastructure, implement monitoring with CloudWatch, Prometheus & Grafana, and document deployment and recovery procedures.

I hold 4 certifications across AWS and Oracle. Outside of cloud work, I enjoy building small games — check out my Game Center!
