About

Back-end developer with 3 years of experience, holding a Master's degree in Web & Mobile Development (ÉSTIAM Metz, 2026). I have worked on vendor products (cybersecurity, cloud) as well as on projects for independent clients. I like understanding the need, designing a clean architecture, and delivering something that runs in production. I also share what I know: I teach a Python course for beginners.

Order Management System(ordering site, opens in a new tab)

layoko-juice.onrender.com

Web and mobile order management applications, designed, built and deployed on my own for an independent client (homemade natural juices), in production. Private GitLab repository.

Background
An independent client sells homemade natural juices and wants to manage and ease her sales. She handled everything by hand: orders came in by phone or by message, and she wrote them down in a notebook.
What I did
Business analysis, requirements specification, architecture, API and two applications, secured CI/CD pipeline, deployment and documentation, on my own, in 1 month.
Solution
A web application for customers (juice selection, cart, payment by Wero or cash, delivery method) and a mobile application for the manager (Discord notification with receipt for each order, order validation and sorting, product management, revenue dashboard). Deployed on Wayhost through a secured GitLab CI/CD pipeline.
Result
In production since August 2026.32orders25customers~10orders / month

Independent project, outside any salaried position (hosted on Wayhost).

AI-assisted development (Claude Code): I led the scoping and architecture, then reviewed, tested and fixed the generated code.

Management app (PWA): catalogue, order tracking, dashboard
