Harold Medrano

AI Product Engineer

I'm a product engineer at Dropout Capital, building AI products end to end, from designing the feature to shipping it.

I live in the TypeScript ecosystem. I build agents with Mastra, MCP servers, SDKs, and CLIs, usually on top of Supabase.

Before that I built data pipelines and FastAPI microservices. I studied Software Design and Development at TECSUP and I'm now doing Systems Engineering at UPC.

My code lives on GitHub and LinkedIn, or drop me a line.

Professional Experience

Product Engineer

Dropout Capital

  • End-to-end product work across four SaaS products: ReallyQuickEmails, Tracking Table, Automify and ROE.
  • Migrated ROE's email delivery from Resend to ReallyQuickEmails behind a feature flag, then dropped the fallback once RQE covered cc/bcc, attachments and multi-recipient.
  • Redesigned ROE's 24 transactional templates and shipped a QA endpoint to test them before they reach production.
  • Took Automify, our Shopify app, through App Store compliance: GDPR webhooks, HMAC verification, OAuth and hardened CORS.
