Back to original languageAbout Lyes
Hello and welcome to my profile! 👋
I am a **Full-Stack Developer & Product Owner**, with over 7 years of experience in creating web and mobile applications, managing digital products, and designing user-centered interfaces. I work at the intersection of development, UX/UI design, and product strategy to design tailor-made, high-performing solutions aligned with business needs.
Specializing in low-code (OutSystems, Power Platform, AppSheet), I combine speed of execution,technical quality, and project agilityto support companies in their digital transformation.
🎯 My Goal
Create digital experiences that are useful, effective, and perfectly adapted to your business challenges.
✨ What I Do
Functional Analysis & Product Scoping
I work hand-in-hand with stakeholders to clarify needs, define user stories, prioritize features, and plan a clear, value-oriented roadmap.
Full-Stack and Low-Code Development
From front-end to back-end, I am involved in the entire development cycle, combining classic technologies (HTML5, CSS3, JS, PHP, React…) with low-code platforms to maximize impact in the shortest possible time.
UI/UX Design & Prototyping
I design modern, accessible, and intuitive interfaces with Figma or by creating consistent Design Systems. My approach is resolutely user-centered, based on testing and field feedback.
Product Ownership & Agile Management
I manage digital products in an agile (Scrum) mode, from backlog creation to delivery, while facilitating project rituals (daily, planning, retrospectives). My role: to ensure a clear, iterative, and sustainable product vision.
I would be delighted to discuss with you and see how I can support you. Together,let's build solutions that make sense and have an impact.🚀
