About Revanza
Senior Backend Engineer from Jakarta with 8+ years building enterprise backend systems, data integration layers, internal productivity platforms, and AI/LLM-enabled applications. I work best where software has to connect messy operations, legacy systems, reporting needs, and real production constraints.
Profile
My recent work sits across backend architecture,
AI/RAG systems, and data platforms for
energy, insurance, and telecom environments. I have built governed
reporting stores from 30+ internal databases, industrial data pipelines
that removed manual Excel workflows, and LLM-powered knowledge assistants
designed for enterprise use rather than demo-only interaction.
Backend architecture for internal platforms, APIs, approval workflows, and operational systems.
LLM/RAG integration with embeddings, vector retrieval, prompt orchestration, and backend inference services.
Data integration and reporting layers across SQL Server, BigQuery, Airflow, NiFi, Power BI, and Microsoft Fabric.
Technical leadership across code review, mentoring, vendor coordination, Agile delivery, and production governance.
