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.
