Salony.com website and apps give salon professionals everything they need to schedule appointments as well as showcase their work. This platform gives clients a place to search, discover, and book appointments. This was a huge project that contained many moving parts. My Tasks: 1. The back-end API (Ruby on Rails) 2. The admin interface (AngularJS) 3. The web interface for a salon owner (AngularJS) 4. Managed and led as the team lead As a result, the client got a working project in less than two months and started receiving the initial feedback from customers. After we received the feedback, we continued upgrading this project and it still requires a great deal more work to do. The most interesting task was to build timetables for selected services so that the customers could see available times in real-time. To build this timetable there were too many instances to take into account. The client could not factor in all the requirements so he delegated this task to me. As a result, we got a great algorithm which solved this problem very quickly and accurately and remained scalable.

Gobgob.com is a chalet and beach house rental service in Kuwait. When I came to the project, I worked with a 3D team which already had started building it from scratch. I came on mid-project so I was required to build it fast and with good quality as I had strict deadlines. I was responsible for developing the business logic of the application and also was managing a team of two front-end developers and two back-end developers. As a result, the client received a working project which started bringing revenue. The most interesting task was to solve the problem of customers who rented the property for a very short period, especial during holidays. We decided to slice a timetable into indivisible pieces (weekend, midweek, full-week, or any dynamic holiday). It was easy to slice but calculating the price depending on a selected dates range that was difficult to manage. In the end, we suggested for them to use Elasticsearch to handle the dynamic calculations and we solved it in a reasonable time. After implementing it, the client continued working on it by adding a special offers mechanism and thanks to TDD, we can implement it very fast without any pitfalls.
