How I work

How I work

01

Discovery

Before defining a solution, I work out who has the problem and what it costs them to leave it unsolved.

02

Prioritization

I rank the backlog by value to the business and to the user, and make explicit what stays out and why.

03

Delivery

I work with Scrum or Kanban depending on context, with clear stories and acceptance criteria engineering can estimate.

04

Measurement

I define indicators from the start so we can decide with data and correct course in time.

05

AI applied to product

I automate processes and experiment with AI and tools like n8n to validate features faster and speed up value delivery.
