§ 1 — Introduction

I'm a Frontend Engineer currently leading frontend architecture at PrudentBit, where I independently develop and scale up enterprise security products like Immunefiles and Immuneshare. Earlier, I developed web applications and component systems at VDOIT Technologies and TechiEco Solutions.

I focus on client-side performance and smart architecture — from engineering direct cloud uploads that cut server bandwidth by 64% to moving ML proctored detection directly onto the client to eliminate network latency.
