01 / ABOUT

Who I am.

I build software from the interface down to the data and systems beneath it. I’m based in Agadir, Morocco.

At 1337 Coding School, my projects have taken me from Unix shells and network servers to containerized services. I also work with Solidity contracts.

Ticketing & artist payments

Festival

Language: Solidity

I built Solidity contracts for festival tickets, event scheduling, artist management, and refunds.

They track ticket counts, set time-based prices, handle artist payments, and restrict sensitive operations and withdrawals to the owner.
