I bridge the gap between robust IT Infrastructure and modern Web Development.
Tech infrastructure, troubleshooting, building web apps, and exploring cybersecurity — Jakarta-based professional with 3+ years in the field.
Curious engineer, security-minded builder
A short introduction to who I am and what keeps me building.
Who I am
A cybersecurity and system integration professional based in Jakarta, Indonesia, with over 3 years of hands-on experience across IT infrastructure, technical sales, and web development.
Currently working as a Presales Engineer at PT Apollo Tekno Solusindo, where I bridge the gap between product teams and clients for system integration, cybersecurity, and IT infrastructure solutions.
What drives me
My journey started with network installation and computer maintenance, eventually evolving into enterprise AutoID solutions, penetration testing, and building modern web applications with React and TypeScript.
I love solving system problems, exploring AI technologies, and pushing boundaries in cybersecurity through CTF competitions and bug bounty programs.
