About Vishal Kumar
I help companies design, build, and scale cloud-native data platforms that turn complex, high-volume data into reliable, analytics-ready insights. With 5+ years of hands-on data engineering experience, I specialise in GCP and AWS, building robust ETL/ELT pipelines, data warehouses, and event-driven architectures that perform at scale.
I typically work on end-to-end data projects—from data ingestion and orchestration to modelling, optimisation, and production deployment—using tools like BigQuery, Airflow, dbt, Pub/Sub, Terraform, Docker, and Kubernetes. I also support AI and GenAI use cases, including LLM integrations and automation workflows.
