About

I left formal studies to ship real systems

I'm Abdullah Hanif. I don't have a CS degree. I stopped sitting in classrooms so I could spend every hour coding, debugging, deploying, and keeping production up.

I founded Xero Sphere AI because local restaurants and pharmacies were stuck juggling separate tools for POS, stock, delivery, and FBR. I wanted one system that actually runs overnight — and it does, at 200+ locations.

I use modern AI tooling to move faster. Architecture, database choices, deploy scripts, and production firefighting are still mine. If you want the long version of how I ship, read How I work. For hard numbers and the WhatsApp engine story, see Engineering notes.

Founder & original architect

Designed the ERP stack — schema to VPS — before hiring help.

Measured under load

1M products, 5 parallel cashiers, p95 50ms on 1 vCPU — my own tests.

Featured work

Xero Sphere AI

Pakistan-focused ERP — POS, FBR, rider tracking, public order panel, and a WhatsApp order engine that doesn't depend on Meta Cloud API fees.

Flagship Live in production

Xero Sphere AI

One platform for restaurants and pharmacies: billing, inventory, compliance, delivery, and WhatsApp orders.

Problem

Shops ran on disconnected POS, stock sheets, delivery apps, and FBR tools that didn't share data.

What I built

Unified ERP on Node.js + SQLite WAL, custom web clients, Android WhatsApp engine with NDK, bare-metal VPS deploy.

My role

Founding developer. Solo-built v1 in under five months. Now lead 3–4 developers while staying hands-on.

Proof

200+ live locations. Load-tested to 1M products. Cold search p95 50ms with 5 parallel cashiers on 1 vCPU.

Writing How I work

No tutorial hell. Four practical phases from research to bare-metal deploy.

Notes Engineering case studies

WhatsApp NDK path vs Meta Cloud API, plus the 1M concurrency report.

Context

Skills over degrees — I'm not alone

Google, Apple, Tesla, and Pakistan shops like Devsinc and Arbisoft hire on tests and portfolios. I apply the same rule to myself: shipped product over transcript.
