Miguel HernandezProduct Engineer

I build products that ship,
sometimes polished, sometimes raw,
always shipped.

Miguel Hernandez

I'm Miguel Hernandez, a product engineer based in Buenos Aires working at the intersection of UX/UI design, frontend development, and product thinking.

I treat AI tools as collaborators. They let me move from sketch to shipped feature in a fraction of the time, without giving up on craft or taste.

I've been a founding engineer on a SaaS, I'm currently senior product engineer on a multi-system flight platform, and on the side I design and ship websites and apps for real clients with real deadlines.

The setup

The setup section
is placeholder, yes.

01

This card does a thing

Placeholder copy goes here. Real words will live here eventually.

02

Another great reason

Still placeholder. I wrote this at 2am. Will replace before client sees it.

03

The third thing™

Classic three-column layout moment. This one stacks. It compounds. It lorem ipsums.

Showcase continues

Showcase section,
not production.

This paragraph is a placeholder. Real copy will be funnier, smarter, and written by someone who slept the night before. Replace before shipping. Probably.

Catchy headline goes here.

This is placeholder copy. The client approved the layout but not the words.

Second card, also impressive.

More lorem-flavored text. Very decision-point.

Bar chart goes up. Nice.

Metrics! Numbers! Growth! This bar chart exists to make the section feel complete.

Branded acronym

The F.A.K.E. Framework

A framework in four letters

Real copy pending.

F

Fictional

Based on a real product. Details changed.

A

Acronym'd

A stood for something once. It still does, technically. Just forgot what.

K

Kinda done

Not shipped yet but vibing hard. K is the placeholder letter of legends.

E

Eventually

E closes the loop. Real copy arrives eventually. That is the whole promise.

Dot goes right

Placeholder follows a linear path.

01

Step one of four

Something happens here first. Very foundational. Possibly involves coffee.

02

Then this happens

Middle step energy. Not first, not last. The quiet hero of the process.

03

Now it gets good

This is where the magic is — according to the deck. Placeholder pending magic.

04

Profit, apparently

Final step. Dot reaches end. Client is happy.

[Creator app]

A creator economy app in active development. Mobile-first product covering monetization, audience tools, and content publishing. Animation shown is a live recreation of a Skia/Reanimated motion system I built for the app — scroll to disturb the waves.
