Hi, I’m Saad Shafiq. Based in Lahore, Pakistan.

SENIOR FULL STACK ENGINEER

I build payment and identity systems that go into production and stay there.

Three and a half years of it. School canteens in Saudi Arabia taking payment from a child’s palm, a toll plaza on the Detroit–Windsor commercial crossing, a licensed sportsbook in Tennessee. I work across the whole stack and currently lead a team of five.

  • fintech
  • payments & identity
  • edtech
  • transport & tolling
  • regulated gaming
  • AI in production

Work

One in full, then the rest

The flagship gets the whole reasoning — the constraint, the decision, where it got to. Everything else gets a card and a live link you can open. Client-owned work is described rather than shown, and says so.

Schoollet parent app: wallet balance in Saudi riyals, service tiles for charging the wallet and limiting spending, and a Telr card-payment sheet.Schoollet canteen app: till screen, billing and the transaction ledger.

Schoollet

School payments, Saudi Arabia

Parents top up a wallet and set spending limits. Children buy lunch at the canteen till with a QR code — or with their palm.

The constraint
Every payment method available to a seven-year-old fails the same two ways: cards get lost and PINs get forgotten. Both are unworkable at a till with a lunch queue behind it.
The decision
Palm-vein biometrics, wired through native Android libraries into both the enrolment app and the point-of-sale scanner. Nothing to carry, nothing to remember.
What happened next
The original developer left mid-build. I had architected the platform, so I took over implementation and ongoing delivery — which is how I know what it costs to inherit a system you only designed.

In use at the crossing

Enteyoes

Gym platform, built solo

Flutter member app, FastAPI backend, Next.js admin console, and an OCR service that reads ID cards so members finish sign-up from home instead of at the desk.

DiPGOS

Document intelligence for construction bidding

A platform that takes a civil-construction tender from automated bid design through to progress control on site. I wrote its document intelligence layer and the retrieval behind its assistant.
