About
I'm Omar — a full-stack engineer in Riyadh who likes the parts of software other people avoid: reconciling ledgers, untangling ERP deployments, and making sure a number on a dashboard can be traced back to the row that produced it.

It started with wanting to see the whole system
I studied Computer Science at Taiz University and finished with Souqi, an e-commerce platform I built end to end. That project set the pattern: I was never satisfied owning only the screen or only the API — I wanted to understand how a request travelled from a tap all the way to a row in a database, and back.
Then production taught me what actually matters
Shipping real systems changed what I optimise for. On the Carry Go warehouse platform I inherited a timer bug that silently overwrote pages every twelve seconds, and found credit-card details being stored in plain text. Neither was in a ticket. Both mattered more than the feature I'd been asked to build — so I fixed them first.
Now I design for the day something goes wrong
That's why I build ledger-first: wallet and inventory balances are derived from append-only records, not stored as mutable counters, so a discrepancy is always explainable. It's why third-party integrations sit behind an anti-corruption layer — a payment gateway going down should degrade one feature, not take the marketplace with it.
And I write it all down
Every system I hand over ships with a README, an install guide and an API reference. I work in two languages and build bilingual Arabic/English interfaces where RTL is designed for, not retrofitted. Code that only I can run and only I can explain isn't finished work.

Mission
Ship software that removes friction from real operations — logistics, retail, finance — with clean architecture that survives contact with production.
Vision
Become a systems-level engineer trusted to own critical infrastructure, from database schema to the pixel a customer taps.
Current focus
Deepening backend architecture (DDD, ledger-first financial systems) while shipping polished, real-time frontends on Next.js and Flutter.
Future goals
Lead the technical design of multi-tenant platforms and mentor engineers building their first production systems.
