Enterprise AI systems

RAG assistants, embeddings, vector retrieval, prompt orchestration, backend inference services, and enterprise UI integration.

Backend platforms

Enterprise APIs, workflow engines, role-based access, audit trails, SQL-backed services, and production deployment.

Data and reporting layers

Airflow, NiFi, SQL Server, BigQuery, Power BI/Fabric, snapshot pipelines, and executive decision-support datasets.

Technical delivery leadership

Squad leadership, code review, mentoring, vendor coordination, and SDLC ownership from design to deployment.

AI and platform proof

Production-minded AI, not demo-only chatbots.

Architected an on-premise LLM knowledge assistant and redesigned it into a RAG pipeline with chunking, embeddings, vector retrieval, contextual prompts, and controlled output handling.
Built an Airflow and Spark pipeline that extracts multi-source operational data into a PostgreSQL data mart for executive Power BI dashboards.
Led 7 cross-functional Agile squads across architecture, code review, vendor coordination, deployment, and operational governance.
