Freelancer profile translated to English.

Back to original language

Description

I develop complete MVP SaaS for startups and entrepreneurs who want to launch their product quickly, without a full technical team.

My goal is simple: transform an idea into a functional application, ready to be tested by real users in a few weeks.

I work on the essential components of a SaaS:

User authentication
Dashboards and business interfaces
Payment and subscription integration with Stripe
Backend and database with Supabase
API integration (including AI if needed)
Rapid deployment on Vercel

I have a pragmatic approach: get to the essentials, avoid unnecessary complexity, and deliver value quickly.

I work on both creating MVPs and improving or unblocking existing projects.
