Bridging the gap between scalable software and intelligent data.
Quiet focus. Precise action. Consistent progress.
I’m Ali Abdelkader Aydi, from Sfax, Tunisia. My journey is defined by a relentless pursuit of knowledge.
I combine software craftsmanship with data engineering to design, scale and deploy intelligent platforms, from cloud-native backends to modern RAG and ETL pipelines.
Software people sign into: MVPs, SaaS products, booking platforms, back offices, and progressive web apps that install and work offline. Ahjez takes bookings for 60+ businesses in Baghdad on the web, iOS and Android.
Sites that present your business and sell: company sites, landing pages, online stores and news platforms, in English, French or Arabic. Fast on a phone, easy for your team to update, built so search engines read every page.
Sites that are an experience: drawn live in the browser, where scrolling moves a camera and every section is a scene, like the fog city you are in and Room 404, a building you walk through. Still smooth on a phone, still read by search engines.
Assistants that answer from your own documents, and the data work behind them: pipelines, dashboards and web scraping. CrocoJobs gathers job postings from seven sources every night into a market of 20,000+, with an agent that answers questions about it.
Technical SEO for React and JavaScript sites, and programmatic SEO that turns your data into pages people search for. Calculi reached 151,765 users with 80% of its visits from search, and no ads.
Deployment, hosting, monitoring and hardening, sized to what your product needs. Scoop News has served 1,000,000+ visitors for a few dollars a month; my own server runs 21 services privately behind a VPN.
