Cover image for The realy 'I' Phone:

The realy 'I' Phone: a CV you navigate and can ask more ZO is incredible. I built an out of the box résumé, entirely on zo.computer (http://zo.computer) and you don't need anything else when you have it. Live: ataleeq.zo.space (http://ataleeq.zo.space) What it is An interactive iPhone, rendered entirely in the browser, that replaces a traditional CV with a fully functional device. Every screen contains real information about me, navigated the same way you already know how. The problem with CVs A CV is a document. Documents get skimmed, forgotten, and lost in a pile. "The CV says I did this. The iPhone says I am this." Every iPhone ever sold is technically a personal device. But when you hand someone your résumé, it's generic, the same template as everyone else. This transforms the device into a mirror: it reflects this specific person, their actual products, their real story, in an interface the whole world already knows how to use. Five apps. One person. In the messages app, I have integrated zo AI, when user go to new message, he can message about me, my work, experience etc.. zo AI will respond according to my resume. (fun fact: you can paste a jd and whether abdur is good fit for this role or not.) In the contact app, I have integrated Gmail and Google Calender, user can email me or can book a meeting. No download. No app store. No friction. Just a link, and suddenly someone is holding your entire professional life in their hands. Built entirely on Zo No external developers. No separate hosting. No third-party infrastructure. Zo feature: What it powers Zo Space, Full iPhone hosted at ataleeq.zo.space (http://ataleeq.zo.space) , no server, no deploy pipeline Zo AI (/zo/ask): Real-time AI chat in Messages, trained on my background Zo Gmail : Contact app "Send Email", routes directly to my inbox Zo Google Calendar: "Book a Meeting", visitor picks a slot, Zo creates the event instantly Zo Assets : All 7 scene photos served as space assets, no external CDN Zo API routes/api/chat and /api/contact as serverless functions inside Zo Origin story Built during my Qatar Airways flight using their Starlink connection. Conceived, designed, and deployed entirely within Zo Computer, one flight, start to finish. Being airborne, I'm unable to post a video walkthrough right now. ZO + Qatar Airways + Starlink
