2018 · Buraimi, Oman

It started on a phone, with a friend's YouTube playlists: HTML, CSS, PHP.

I had about 100MB of mobile data a month.

So I downloaded the videos on a mall's free wifi.

Every MB counted.

…and that was the month.

One more bar. Please.

Download now. Watch later.

Closing time. Videos: saved.

Then I practised offline at home.

Very little connection. Enough to start.

Sometimes I dozed off… errr.

No internet. Still a website.

What the foundation became.

01

Buraimi, Oman · 2018

Self-taught, one small lesson after another, until the first thing I built finally worked. It laid the foundation every system since has been built on.

    reporting · query performance

    In Quore, a reporting product, reports over tables of up to millions of rows, some too slow to use and some whose filters failed. I rewrote their queries with composite indexes and fewer join hops.

    • 200+ stored procedures

    Also, in a team of 4, a visual SQL query builder, delivered to beta.

  9. Dealer auction platform

    with a team · across the whole stack

    A national automotive OEM sells its used cars to registered dealers, in live auctions and sealed tenders. Bids land on every dealer's screen at once, a late bid extends the countdown for that car only, and a dealer who drops out comes back already caught up.

    • 150+ used-car dealers
    • 160+ live auctions
    • 10+ tender auctions
    How it's built

    A Laravel core with queues and notifications, a NestJS WebSocket gateway for the bidding, the dealer portal and the auction CMS, third-party payment processing that never counts a callback twice. I led the move of its pipelines to Azure DevOps and of staging to a new IIS server.
