Hybrid business and engineering profile, I drive SaaS products from scoping to production.

I built my career in two phases: nearly 4 years on the business side driving digital projects, then 4 years in full-stack development, including 2.5 years leading a team of 5.

Today I drive software and web applications end to end, bridging business needs, users and technical teams. This dual background lets me combine functional design and hands-on technical expertise (TypeScript, React, Node), within Agile Scrum environments.
