Building intelligent interfaces
where great design meets
GenAI-powered engineering.
I’m Yassir Sabbar, a 24-year-old fullstack developer based in Lyon, France. I build modern web products with React, Next.js, Node.js and PostgreSQL, and I bake AI into them — retrieval, agents, assistants, and intelligent interfaces that actually ship.
My thing is the full lifecycle: from architecture and design to CI/CD, observability and production hardening. Clean Architecture, measured performance, and interfaces that feel effortless.
Currently working at Ouiactive in Lyon, with past stops at ORNISEC (Rennes), DEKRA (Casablanca) and MOBIBLANC — shipping cybersecurity platforms, quality-ops tools, and backend APIs across .NET, Symfony, FastAPI and Node.
Outside the terminal: open source, design, podcasts, travel, and a soft spot for the boundary between product and poetry.
A transfer bank built as three .NET microservices — ledger, payments saga and fraud desk — cooperating over RabbitMQ. Load-tested at 25 transfers per second on the same two accounts without losing, creating or duplicating a cent.
A 2014 ASP.NET MVC 5 / AngularJS order system migrated route by route to .NET 10 and Angular 22 behind a YARP facade — no big-bang rewrite. The new pricing is proven equal to the legacy stored procedure by differential tests.
Insurance claims handling — declare, review, approve and settle — with the safeguards of a regulated business and an AI reviewer that backs every finding with a quoted page of the policy.
AI-powered multiplayer narrative game where players co-create stories with a real-time game master LLM. Built the full stack — from live session orchestration to the storytelling engine. Shipped with a team as a capstone workshop project.
AI-powered CI/CD optimization platform that turns slow pipelines into fast, intelligent deployment workflows. Connect a GitHub repo, auto-analyze workflows, and get actionable recommendations with measured impact.
Beautiful animated UI components for Blazor — the Aceternity UI equivalent for .NET. Shipping what the Blazor ecosystem was missing: spotlight glows, meteors, 3D card tilts, shimmer buttons, and more, all NuGet-installable.
High-performance weapons of choice for digital construction.
A chronicle of persistence and problem solving.
