Freelancer profile translated to English.

Description

I design and develop custom web applications in Next.js — from rapid MVPs to full-fledged SaaS platforms.

Self-taught, I founded SponsorsMetrics (sponsorsmetrics.com): a live SaaS used by YouTube creators to automate their sponsorship reports. I managed the entire project alone — Next.js architecture, YouTube Analytics API, OAuth authentication, PostgreSQL database, cron jobs, emailing system, and Vercel deployment.

What I build for my clients:

Web applications and SaaS (Next.js, React, TypeScript)

Third-party API integrations and analytics dashboards

Custom automations and workflows

AI integration (OpenAI API, assistants, intelligent features)

What sets me apart:

I am a developer AND a product founder — I understand business challenges, not just code. I speak 5 languages (FR, PT, EN, ES, DE) and work equally well with Swiss and international clients.

Available for remote or French-speaking Switzerland assignments.
