About Me
Hi! I’m David, a data engineer with a full-stack background spanning networking, cloud infrastructure, and end-to-end data pipelines. I started my career hands-on with LAN/WAN design and server deployments, gradually evolving into cloud infrastructure and data-driven projects. Over the years, I’ve built robust ETL/ELT pipelines, migrated legacy systems to modern cloud architectures, and enabled data-informed decision-making across organizations. I’m passionate about MLOps and AI/ML workflows, experimenting with model deployment, automation, and workflow orchestration. I also run The Data Mothership, a weekly newsletter where I share insights and experiments in data engineering and analytics.
