SCROLL · THE WHOLE STORY

Muhammad Sajawal Khan
THE STORY · FOUR CHAPTERS

01 · LAHORE · 2016 TO 2020

Real constraints make better engineers.

A software engineering degree at PUCIT, then a first job teaching machines to see: computer vision models at OMNO AI that had to run fast on cheap edge hardware. No budget for waste, no room for almost-working. That job set the pattern for everything since.

02 · FOUNDER, FIRST ATTEMPT · 2021 TO 2022

Code is easy. Companies are not.

In 2021 I co-founded Eshtyle, a multi-vendor e-commerce platform, and learned the difference between writing software and running a business. Then serverless systems at Xgrid, 50K requests a day, where I learned what scale does to careful plans.

03 · THE UK CHAPTER · 2023 TO 2025

New country, bigger systems.

Moved to the UK for a masters at Northampton, led a real-time computer vision platform on the side, then ran data engineering at Phipps Henson McAllister: 10,000+ clients migrated between accounting platforms and LLM systems in production for people who do not forgive downtime.

04 · NOW · 2026

CEO by title, engineer by hand.

Today I run Placewise AI, voice agents that interview candidates on autopilot, and I still write its code. ReachWise builds AI for other businesses. Wise Route, WiseApply and BritWise help people make the UK home, the way I did. And through KhanX Tech I teach what the shipping keeps teaching me.
