Nowi / Argentinian software engineer in Montréal
I build thoughtful products and help teams do their best work.
I’m an Argentinian software engineer and ITBA graduate living in Montréal, with 10+ years turning complex ideas into useful, accessible products.
01 / About me
The person behind the timeline.
Hey, I’m Nowi.
My name is Noelia López, but online I’m Nowi. I’m a software engineer and ITBA graduate who began her career in Argentina across fintech, marketplaces, and product studios. Today I’m based in Montréal and collaborate with teams and clients across borders.
I’m happiest when a problem is still a little messy: researching the context, asking the useful questions, shaping a technical direction, and turning it into an experience that feels clear. I move comfortably between hands-on frontend work, product thinking, technical leadership, and mentoring.
