👋 Hello!

I am a DevOps & Cloud Engineer (SDE-2) at Barclays specializing in AWS Cloud, Infrastructure as Code, and CI/CD automation, focused on building secure, scalable, and production-ready systems. I take ownership from design to deployment—automating infrastructure with Terraform, delivering resilient cloud architectures, implementing zero-downtime deployments, and shipping reliable CI/CD pipelines. My work supports mission-critical platforms like the Amazon Arrow Card, including multi-region AWS deployments, disaster recovery solutions, and CTO-approved strategic initiatives.

I enjoy solving high-impact problems by creating automation tools, improving observability, optimizing cloud costs by 40%, and enabling teams to ship faster with confidence across AWS, GitLab/Jenkins, Terraform, Kubernetes, and Docker. I've also won multiple hackathons, where rapid prototyping and execution under pressure strengthened my ability to turn ideas into working products.

Driven by a bias toward action, I continuously build cloud-native, AI-powered projects with a simple philosophy: automate it, secure it, and scale it safely.
