Demo profile

Full-stack Developer - Startups & MVPs

Rosario, Argentina·5+ years·Spanish / English

Bio

I ship fast and iterate based on user feedback. 5 years building MVPs for startups where speed and learning matter more than perfection. I can wear multiple hats - frontend, backend, some DevOps, basic design. My superpower is cutting scope ruthlessly while keeping the core value. Liberal arts degree, learned to code at a bootcamp, thrived in the chaos of early-stage companies. Great at async communication and working with non-technical founders.
