The salesperson who builds

It's rare to find someone who can both sell and build. I do both: I sit with the customer, find the number that matters, and come back with a system that works.

David Bajonero, AI systems builder in Bogotá

Where I add the most

  • AI Solutions Engineer
  • Sales Engineer (AI products)
  • GTM Engineer
  • AI Solutions Consultant
  • Forward Deployed Engineer (customer-facing)

What I already do: discovery, scoping, demos, proposals and shipping tested systems with agents. What I don't claim: years as a career engineer.

In five numbers

  1. 10+ years in sales and service, about 7 of them in English, targets beaten at Asurion and Honda ⓘ
  2. Own online store in production since 2023, built and run with my wife empireessence.co ↗
  3. 1st place, Claude Code Build Day, Bogotá, October 5, 2026 ⓘ
  4. QA harness: 20 of 20 checkout cases green in about 65 seconds, challenge winner evidence ↗
  5. Restocore: 396 automated tests and a security review with no critical or high findings ⓘ

What I bring

Customer discovery: the right questions, objection handling, three-option proposals and closing

End-to-end building with agents: from idea to a product with tests, roles and backups

Cost judgment: I pick models and architecture based on what they cost to run every month

Technical honesty: evals, acceptance cases and clear status labels (demo, pilot, production)

CRM and sales ops: Salesforce, pipeline, objections and account management every day

Native Spanish and advanced English: about 7 of my 10+ years in sales were in English, with US and global customers
