harold18m - Overview

Hi, I'm Harold Medrano 👋

Software Developer focused on building real products for startups.
I work mainly as a Full-Stack Developer with TypeScript, integrating AI features into real product flows, not demos.

I care about shipping, clarity, and business impact.


🧠 What I do

  • Build end-to-end web products (frontend, backend, data).
  • Develop internal tools and dashboards used by real users.
  • Integrate AI into products (automation, content generation, vision-based flows).
  • Work in fast-paced startup environments where execution matters.
