What I'm looking for

I’m looking to architect secure, high-availability backend systems and integrate RAG/Agentic AI workflows that scale. I want ownership of system design, clean APIs, and strong security models (RBAC/ABAC) with collaborative product delivery.

I’m a Middle-Senior Backend Engineer focused on building high-availability services and AI-integrated architectures. I bring deep technical proficiency in Go, Python, and JavaScript, with a strong emphasis on designing core enterprise systems from the ground up.

In my current role at Telkom Indonesia, I’ve built an enterprise-grade user management system using Attribute-Based Access Control (ABAC). I architected and implemented RESTful APIs with Node.js and Go, designed normalized relational schemas for complex permission hierarchies, and supported multi-tenant access policies.

I also developed a Knowledge Management System using Retrieval-Augmented Generation (RAG), including document ingestion, vector storage, embedding pipelines, and query interfaces. I integrate Agentic AI workflows to automate retrieval and improve responsiveness to complex user queries, while keeping security and maintainability at the center of my system designs.
