I am a Backend Engineer from Yogyakarta, Indonesia. I have strong hands-on experience in implementing robust backend architectures, managing transactional state integrity, and integrating secure payment channels.
Lately, I have been designing and building intelligent multi-agent runtimes integrating LLMs and Retrieval-Augmented Generation (RAG) workflows to automate complex development and operations tasks.
