Software Engineer · Product Builder
Ahmad Mujahid Abdurrahman
Bandung, West Java, Indonesia
Lazy software engineer who loves to deliver product. Pragmatic by nature — not a tech-stack fanboy. I enjoy building scalable backend systems and SaaS products from idea to production, and I'm in the middle of shifting into product engineering. Open to collaboration, mentorship, or just talking about tech.
