Background

7+ years of software development experience, including several years as a senior engineer within an international company. I have designed and shipped complete platforms — from backend architecture to mobile apps — in retail, healthcare and services.

Co-creator of Waitiii, a queue management SaaS with paying clients in production. I also design and build GVA Horizon, a smart urban assistant for Geneva combining 63 data sources and conversational AI; SharkRoast, a satirical website audit platform with a dual Gemini + Claude pipeline; and I shipped Lavande Maison, an artisanal e-commerce live in production with multi-type catalog and Stripe payments.

My background covers the full product lifecycle: specifications, architecture, development, testing, deployment, monitoring and iterations based on user feedback.

Approach

I design products end to end: from backend architecture and data modeling to the mobile user experience. Every technical decision is driven by reliability, maintainability and the value delivered to the end user.

Experienced in multi-tenant and regulated environments, I favor robust and testable solutions. AI is a lever I integrate when it brings real value — personalization, automation, analysis — not as an end in itself.

My approach is pragmatic: ship a product that works, handles the load and is built to last. Code quality and performance are never negotiable.
