What I'm looking for

I'm looking for an opportunity in Germany where I can build reliable cloud platforms, Kubernetes environments, CI/CD automation, and AI-enabled MLOps workflows. I can join immediately and hold a German Chancenkarte.

I'm currently building an AI Automation Platform for TEC QUBES (AB InBev), where I design enterprise CI/CD pipelines across multi-region Azure environments and enable zero-downtime releases. My work improved deployment stability by 30% and reduced release failures by 25% through blue/green deployments and automated rollback.

I've also built LLM-powered QA automation with GPT and LLaMA, cutting QA cycle time by 40%, and established MLOps workflows for model versioning, promotion, and deployment. Using LangChain, LangGraph, and RAG-based validation workflows, I achieved 95% alignment accuracy while reducing manual review effort.

Across Happiest Minds, Exhale Tech Systems, and Refex Energy, I've led Azure and GCP migrations, deployed Kubernetes platforms, implemented Terraform-based infrastructure, and strengthened observability, security, and cloud networking for enterprise applications.
