The founder of BUILD FAST
Systems architect.
Founder and CEO of Digital Casa, an entrepreneur at heart and a developer by discipline. I design systems that turn ideas into profitable companies, and I am the face and the guarantor of every product that leaves Digital Casa. With no funds and no outside investor, software was my only way to build: I invested in my expertise and my character.

My journey
2012
Self-taught, I learn by building: the web, databases, servers. An obsession is born: understanding how everything fits together, from the click to the payment.
2012–2018
Alongside the code, a learning path that keeps widening: entrepreneurship, social and spiritual questions, and many other fields that touch entrepreneurship from near or far. One direction behind it all: to be an entrepreneur.
2018
High-traffic backends, e-commerce platforms, critical migrations: I ship to production for demanding companies.
2019
I complete the only year of my life spent as an employee: one year at Facnote, a small French company, working entirely remotely. It confirms what I already knew: my road is to build my own.
2020
In Algiers, 100% self-funded and founder-led. Every product goes from a blank page to its first paying customers: architecture, code, infrastructure, and first sales closed by me.
2021
The first big Digital Casa product: an entire e-commerce marketplace in the spirit of eBay, with sellers, buyers, listings and payments, built from scratch.
2022
The first version of Stoycway: a network connecting students and teachers.
2023
I step outside development and programming to learn and experiment in other fields: finance, crypto, taxes, economics, geopolitics, psychology and negotiation, and politics, which I studied in depth. Not on the surface: I go deep into the technical mechanics and the sound concepts behind them. An entrepreneur has to understand how money, rules, power, people and markets really work.
2024
We build a high-volume telecom-services platform and sign a very large contract. We delivered our side in full; the counterparty never carried out theirs.
2025
A whole new codebase, built AI-first: the second version of Stoycway, where you upload your own courses and it answers, summarises and generates flashcards, quizzes and study plans, with sources cited. It is also the first brick of what will become KnowledgeOS.
2025
The same year, I deliver in 10 days the full migration of a major brand site before the festive season: €180k profit for our client, 14,789 customers migrated with no downtime.
2025
ENSIA, GAAN, Huawei, COSOB, Algérie 2030, University of Algiers 3: I go out to meet the people moving Algeria's digital scene forward.
2026
In early 2026, KnowledgeOS is born: an operating system for knowledge. It now runs under the hood of Stoycway as its engine, turning your own courses and documents into something you can ask, revise and build on.
2026
Kayroo, the SaaS for Algerian merchants, launches in 2026. Kayroo Events follows two months later.
2026
At ENSIA, I supervise ten interns who deliver an AI marketing extension for Kayroo (Facebook ads via API, up to the payment button, which the client reviews so funds are never lost). I also sign with a recognised artist in Algeria and on the international scene.
2026
At Formatech Expo, I launch BUILD FAST: a master class, then the Build & Train programme, built and guided by Digital Casa.
Next
Several startups a year, AI-driven and innovation-driven, guided all the way to profitability. For Algeria, with the means we have.
Expertise
Complete systems (data, roles, payments, queues, multi-tenancy) that handle the load and stay easy to evolve.
PHP 8 and Laravel, Next.js, React, Vue, Livewire, Alpine, Tailwind: from backend to pixel, seamlessly.
Two-factor sign-in, strict CSP, rate limits, audit logs, backups: platforms that hold up under real traffic and real attacks.
Docker, Nginx, servers, SSL, monitoring, backups: I deploy and maintain what I build.
RAG, vector databases, OCR, agents, voice, multi-model (GPT, Claude, DeepSeek): AI wired into real use cases.
Business models, pricing, SATIM payments, first sales: I think about every product as an entrepreneur, not an executor.
How I think
A platform is only worth something if someone pays for it. I always start there.
If an AI feature saves neither time nor money, it doesn't belong in the product.
The best technical choice is the one that costs least to build, run and maintain.
Nobody excels at everything. I partner with recognised experts for legal, sales and marketing.
A live product that learns beats a perfect product that waits.
Who I am at the core
I believe that in Algeria, one well-equipped, well-surrounded person can build a company that matters, and that my role is to help as many people as possible get there. I'm demanding about quality, obsessed with profitability, and I remain accountable for every project that leaves Digital Casa: when a product carries our name, it carries mine too. Entrepreneurship has always been the destination. With no funds and no outside investor, software was the only way there, so I invested in myself: my expertise and my character.
My vision
“Make BUILD FAST the factory that turns Algerian ideas into profitable, AI-powered startups, one cohort at a time.”

In the field
Fairs, schools, conferences: I go out to meet the students, entrepreneurs and institutions moving Algeria's digital scene forward.

Born in 2022 as a network of students and teachers, reborn in 2025 as a 100% AI-driven platform: upload your courses and it answers, summarises and generates flashcards, quizzes and study plans, with sources cited. Since early 2026 it runs on KnowledgeOS, its engine under the hood.

E-commerce · SaaS · 2026
The all-in-one SaaS for Algerian merchants: store, catalogue, payments, delivery, CRM, and an AI that writes copy and creates visuals. In 2026, ten ENSIA interns I supervised added an AI marketing extension: Facebook ads automated through the API, up to the payment button, which the client must review before any funds are committed.
Critical rebuild · 2025
A major brand site, built on an ageing architecture, had to switch technology completely and migrate before the festive season, so it would not miss the biggest revenue of the year. 14,789 customers migrated with no downtime or data loss.
E-commerce · Matchmaking
A marketplace-style e-commerce platform that connects businesses with each other: sellers, catalogues, orders and payments in one place.
Live
Events · 2026
Launched in 2026, two months after Kayroo: elegant digital invitations with a sealed envelope, countdown, real-time RSVPs and QR check-in. Shared on WhatsApp, no app needed.
Soon
Voice AI
The AI voice studio for marketing videos: script, natural voices and consent-based cloning, in 23 languages including Darija.
Telecom
A distributed telecom top-up infrastructure: native Android app, USSD and SMS automation, real-time monitoring.
EdTech · Voice AI · 2026
Signed in 2026 with a recognised artist in Algeria and on the international scene: an AI-powered music teaching platform with voice cloning.
EdTech · Kids
A trilingual language-learning app for children in Arabic, French and English: playful, guided, designed for home and school alike. Kidspeak is the demo name, not the final brand.
One call is enough to know whether your project belongs in BUILD FAST or deserves its own platform.
