About

Self-taught from the start — Wildan began by building and running game servers, learning backend systems and server administration well before security research became the focus.

That foundation grew into SentinelX: responsible disclosure work, infrastructure management, and a line of independently built security tooling and products.

SentinelX now operates as an independent practice — research, development, and product, under one name.

Based in Wonotunggal, Kabupaten Batang, Jawa Tengah, Indonesia — deeply rooted in the local tech community.

Today, WildanDev also builds websites — modern, responsive, SEO-friendly — for clients across Indonesia, backed by the same security-first mindset.
