From MVP to app in production — with a product mindset, not just code.
I'm Douglas Ennes, a Senior Flutter developer with a postgraduate degree in Product Management. I build cross-platform applications (Android, iOS, and Windows) from zero to deployment, for anyone who needs a technical partner that understands the business — not just someone who writes code.
