Alonso Lamilla (aka Arturo Bandini)
Product Builder · Product Manager · Product Analyst
I turn ambiguous customer and business problems into measurable products. My work sits at the intersection of discovery, product strategy, product analytics, growth experimentation, AI, and hands-on delivery - from framing the decision to shipping and measuring what changed.
How I work
01 /Discover
Interviews, operational signals, and product analytics to make the problem observable.
02 /Decide
Trade-offs, clear success criteria, and PRDs that turn evidence into an executable bet.
03 /Build
Prototypes, automations, and technical delivery with the team - not hand-offs into a void.
04 /Measure
Product metrics, growth loops, and evaluations that tell us what changed and what to do next.
