§ 1 — Introduction & Biography

I am a Frontend Software 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, modern frontend architecture, and edge intelligence - from engineering direct cloud uploads that cut server bandwidth by 64% to moving ML proctored detection directly onto the client to eliminate network latency.
