CHAPTER II · ORIGIN · 100% SELF-TAUGHT

The builder
behind the systems.

@mkr_infinity · India · Since 2016

I started with Android modding in 2016, sparking my drive to understand how systems work at the deepest level. No formal degree — 100% self-taught by experimenting, breaking systems, and rebuilding better versions. Today I build high-impact web tools, automation workflows, and AI-powered products focused on simplicity, speed, and practical real-world usefulness.
