About
Backend-first engineer with 7+ years of experience building production systems for telco, banking, e-commerce and education. Currently Lead Backend Developer for the Telkomsel Poin platform at PT Mitra Bhakti Informasi.
My comfort zone is the invisible part: reward pipelines in Kafka that must never lose an event, security layers that hold back phishing, cache layers that genuinely reduce load. I still build the frontend (Vue, Vuetify, AngularJS) when a product needs end to end delivery.
Recently my focus has widened to AI agent integration: a multi-model AI gateway with automatic fallback, and Hermes Agent for workflow automation. Not a demo — it runs on production servers every day.
