Senior Backend & AI Systems Engineer · Jakarta

Backend, data and AI systems that hold up in real operations.

I'm Revanza Raytama. For more than nine years I've built platforms for energy, telecom and insurance. Today I lead technical delivery at a Pertamina subsidiary, and on the side I build MeatLink, a live B2B meat commerce platform, with a partner.

What I work on

01

RAG pipelines, embeddings and vector retrieval, MCP servers and tool calling, with guardrails enforced on the server and evaluation before trust.

02

Backend platforms

.NET, Laravel and TypeScript services: APIs, approval workflows, role-based access, audit trails, payments and event-driven processing.

03

Data & reporting

Airflow and Spark pipelines, SQL Server and PostgreSQL marts, Power BI and Fabric dashboards that leadership reads every day.

04

Technical delivery

Leading seven cross-functional squads and vendor developers: architecture, standards, code review and production rollouts.
