Felix Brillant

AI / Cloud Data Engineer focused on production-grade AWS platforms, real-time AI systems, analytics engineering, and enterprise-scale data workflows.

About Me

AI / Cloud Data Engineer focused on building production-style cloud and AI systems across AWS infrastructure, analytics engineering, orchestration workflows, retrieval-augmented generation (RAG), and real-time intelligent pipelines.

My work combines cloud architecture, data engineering, AI engineering, validation frameworks, observability, and executive analytics platforms designed around production-oriented engineering practices.

I specialize in AWS-native systems involving Athena, Glue, Terraform, Step Functions, Kinesis, Power BI, vector databases, orchestration pipelines, and large language model (LLM) workflows.
