Vo Ky Truong · Technical Product Owner

Steer, prioritize,
ship.

I take products by the hand across four grounds: AI & GenAI, platforms & API, SaaS B2B & B2C, cloud & DevOps. From strategic fog to a useful, measurable feature, with nobody in between. Freelance or full-time, fully remote or hybrid in the Paris region.

  • 8 years of Product Ownership
  • Many products owned
  • MSc-level engineering degree
  • TOEIC 945/990
Product owner role: vision, roadmap, backlog, prioritization, and impact

Your product deserves a direction.

Too many ideas, an overflowing backlog, priorities that shift every week. I put the product back on course: a clear vision, a roadmap that holds, a backlog prioritized by value. You set the direction, I turn it into delivery.

A direction, not a to-do list

A vision, a roadmap, priorities that hold over time.

Value first

I arbitrate by value, risk, and effort. Not on gut feel, not on whoever shouts loudest.

From fuzzy to shipped

I drive it through to production, not just the scoping.

Products I've owned.

Not theory. Three SaaS I took from vision to launch: scoping, roadmap, trade-offs, delivery. The PO who decides, and who sees the result running in production.

How I take the helm.

  1. 1

    I listen to the product

    Goals, constraints, what's stuck today. I find the real problem before rushing in.

  2. 2

    I set the course

    Vision, roadmap, backlog prioritized by value. The whole team knows where it's going.

  3. 3

    I drive delivery

    Agile rituals, trade-offs, increments shipped sprint after sprint.

  4. 4

    I measure, I adjust

    Analytics and field feedback. The roadmap follows reality, not the other way around.

The full palette.

The detail, if you want to see everything. What matters is above: the course held, and the products shipped.
