The story · 4 chapters

Things I picked up along the way.

01Lahore · 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.

02Founder, 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.

03The 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.

04Now · 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.

The timeline · 7 marks

Ten years, measured.

Grab the ruler and pull

  1. 2016

    Started software engineering at PUCIT, Lahore. First real code, first all-nighters.

  2. 2020

    Graduated with honours, went straight into deep learning at OMNO AI: computer vision on the edge.

  3. 2021

    Co-founded Eshtyle, a multi-vendor e-commerce platform. First taste of building a company.

  4. 2022

    Senior engineer at Xgrid, running serverless systems at 50K+ requests a day.

  5. 2023

    Moved to the UK. Masters at Northampton by day, real-time computer vision by night.

  6. 2024

    Senior engineer and IT department lead at Phipps Henson McAllister: 10,000+ client migrations, LLMs in production.

  7. 2026

    Founded Placewise AI, voice agents that screen candidates on autopilot. Built this site in public.

Four hats, one head

Five-plus years of Python, AI and cloud systems: serverless backends at 50K requests a day, computer vision at 30 frames a second, and LLM systems that hold up in production.

Co-founder and CEO of Placewise AI, and still its lead engineer. Second time around: Eshtyle came first. Reachwise runs the services side.

Mentor to 50+ engineers worldwide on architecture, LLM applications and careers, through KhanX Tech and office hours.

500K+ views of technical content across YouTube, LinkedIn, Instagram and TikTok as KhanX Tech. Teaching in public is how the lessons stop being private.

That's the story so far. Here's the work.
