Experience

Product Specialist — AI Transformation — Pactum AI

Jul 2025 — present · Tallinn, Estonia · Full-time

Officially Product Specialist in the Engineering department; in practice an internal AI platform and enablement role. Pactum builds autonomous procurement negotiation software for Fortune 500 companies — I build the internal capability to use AI, rather than the customer-facing product.

  • Lead the company-wide Claude Code rollout, including to non-developers — training, 1:1 setup sessions, and an internal skill distribution system.
  • Designed the internal AI forum structure: retired two overlapping weekly syncs and replaced them with a biweekly AI Guild Meetup (technical) plus AI Fluency Lab (non-developer learning track).
  • Own the Pactum Engineering Handbook migration to Confluence, including tooling that flags stale pages automatically instead of by nagging.
  • Ship Claude Code skills to an internal marketplace — handbook lookup, red-flag review, and a meta-skill for sharing skills.
  • Drive access and governance decisions: plan tiers, MCP permission scoping, connector risk review, token budget.
  • Built and shipped a client-facing issue tracker feature to full adoption across a product line in six weeks.

QA Engineer, Proxy Product Owner & Acting Scrum Master — Raintree Systems

Apr 2023 — Jul 2025 · Remote · Full-time

US healthcare EMR company. Three concurrent roles across the Custom Services, Communications and Clinical teams.

  • Designed the company-wide test automation strategy, conventions and best practices; wrote and documented Cypress tests in JavaScript and TypeScript.
  • Acted as Product Owner and Scrum Master for the team serving one of the largest therapy clinic chains in the US, including direct client calls.
  • Analysed complex clinical workflows into user stories and acceptance criteria; ran refinement, retros and cross-team planning.
  • Mentored new hires and ran product demos for stakeholders.
