Hi, I'm Helena 👋

Product manager with 5+ years in fintech and startups — most recently owning embedded lending products at Banxware — who spent 2026 going deep on the technical side: full-stack development with Ruby on Rails, AI product building with low-code tools, and data analytics.

My background is a B.Sc. in Psychology and an MBA, which is why most of what I build circles the same question: how do you make good habits effortless?

🗂 Product portfolio — projects with demos and walkthroughs

  • Code — Ruby on Rails, SQL, JavaScript, Python
  • AI & automation — OpenAI APIs, RAG pipelines, AI agents, n8n, Supabase, AI-assisted development
