Questions about this work

Who builds these projects?
Every project on this page is designed, engineered and deployed by Dr. Khaled Jassem — a full-stack programmer, founder and researcher — most of them delivered through his digital studio, Startup13. They are built from scratch in code, with no templates or page builders.
What technologies are used across the portfolio?
Primarily PHP and MySQL for back-end systems, with vanilla JavaScript (and single-page-application architecture) on the front end. Individual projects also use SQLite, Pine Script, SheetJS, jStat, OAuth integrations, OAI-PMH and the WhatsApp Cloud API, chosen per project rather than by default.
Are these real, live projects?
Yes. They are production systems and shipped products — a 7-site academic publishing platform, a UAE luxury-car marketplace, a 27-module ERP in daily use, a statistical-analysis SaaS, a TradingView indicator, a salon operations system and an internal data tool — not demos or mockups.
Can I get a similar system built?
Yes. Custom platforms, marketplaces, ERP/CRM systems, SaaS products and internal tools are all available, usually through Startup13. The starting point is a short email to hello@khaledjassem.com describing what you need.
