I'm a product engineer. I build AI products end to end.

Eight years shipping web and mobile products, most of it now spent building with LLMs: RAG, agents, evals, and voice. I like owning the whole arc, from talking to users and shaping the product to designing the UX and writing the code that ships.

Case Studies

What people I've worked with say

Hanif quickly understood our needs, both from a business and aesthetic perspective, and translated them into a clean, functional website in no time.

Monica Londoño Co-founder, Punto de Partida

He's reliable, communicates great, and has a sharp technical mind. Whether handling complex builds, troubleshooting under pressure, or adapting to shifting priorities, he was dependable every step of the way.

Markis Zarate Founder, Zarate Studios

He suggested design-to-engineering hand-off improvements to make our workflow more efficient, asked insightful follow-up questions during design reviews, and brought my Figma designs to life so we could deliver value to our users.

Sarah Hibner Senior Product Designer, LeagueApps

A bit about me.

I started out as a software developer and grew into a product engineer: someone who cares as much about what we build and why as how it's built. I've shipped a Spanish reading app end to end, taken AI products from demo to paid, and done senior product engineering for teams like LeagueApps. I'm happiest close to users, making the call on scope, UX, and architecture in the same conversation, then shipping it.

Based in Buenos Aires, working US hours.

More about me

Where I think this is going.

I care most about AI that keeps the person in the driver's seat. Not automation that quietly replaces people, but tools that make us better at creating, learning, and thinking for ourselves. Copilots for making things, tutors that actually teach, AI that can show up inside a real conversation. That's the kind of product I want to help build.

Let's talk.

If you're building something where a product engineer who can own the whole arc would help, I'd love to hear about it.
