About

I’m a Cloud and MLOps engineer with hands-on experience deploying and scaling infrastructure in AWS and Azure. I’ve built systems from scratch that power real-time analytics, IoT device fleets, and AI model deployments. At UBS, I contributed to the cloud infrastructure supporting the AI Development Studio, helping 100+ internal users access GPU-backed Kubernetes environments while reducing vendor costs. In a previous role, I built CI/CD pipelines, automated firmware deployments, and processed over a million daily sensor readings through AWS Kinesis Data Streams, IoT Core, serverless functions and a number of database services for optimal and cost effective data pipelines. I enjoy solving infrastructure problems, improving reliability, writing highly scalable backends, and learning from experienced teams. I’m currently working toward my next AWS certification and looking for a high performance engineering team where I can grow and contribute.
