Freelancer Overview

Founder & GTM Engineer focused on AI training and evaluation. I bring 15+ years of professional experience across complex workflows, operations, and product work, and 3 years hands‑on with AI agents and prompt‑driven systems. I design realistic scenarios where agents operate across email, calendar, CRM, and internal tools, then evaluate their outputs for reasoning quality, correctness, and usefulness. My strengths are text‑based evaluation and rating, scenario and task design, and clear, structured feedback. I’ve led QA and usability testing in B2B SaaS (checklists, acceptance criteria, test plans) and done extensive prompt engineering and copy review (outbound messaging, social content, newsletters). I’m comfortable with structured tools (Jira/Asana, Airtable‑style tables, JSON‑like configs) and multi‑stakeholder workflows, and I’m used to providing precise, rubric‑aligned feedback that improves AI model behavior.
