I build institutional websites, functional sites and web applications.

Designed, built and shipped end to end — from the first line of backend code to the interface a client actually uses.

About

Portrait of Alvaro Aramayo Chain
Alvaro Aramayo Chain

Hi, I'm Alvaro. I make web products that hold up once real customers start using them.

Most of my work sits where a website stops being a brochure and starts doing a job — taking a booking, sending the confirmation, remembering to follow up. I care about the boring parts: clean data, sane backend structure, nothing that falls over on a busy Saturday.

I usually work the whole flow solo: scope it out with whoever's asking, build the backend and the interface, wire up WhatsApp and email so nothing gets forgotten, and stay close after launch to fix what actually breaks — not just what looks broken. Studying cybersecurity alongside that pushes me to default to systems that are hardened from the start, instead of patched after something goes wrong.

    End to end

    One person across backend, interface and integrations — fewer handoffs, fewer things lost in translation.

  • 02

    Automation-minded

    If a step repeats — a reminder, a confirmation, a follow-up — it belongs in the system, not on someone's to-do list.

  • 03

    Security-aware

    Cybersecurity study feeds back into the day job: data handled carefully by default, not as an afterthought.

Real products, built end to end.

Page in development

Something new is coming.

Our new site is on its way — in the meantime, reach out and we'll get back to you.

Your Business Name · Since day one

"Coming soon" placeholder page

A simple single-page site for a business whose real website isn't ready yet — a clear message and a way to get in touch, live in minutes instead of waiting on the full build.

Role

Type
Single-page site
Status
Reusable template
  • Fast to deploy
  • Custom branding
  • Email capture
  • Mobile-first

Demo only — the form doesn't send anywhere. Same idea I'd set up for any client: swap the name, colors and message and it's ready to go live while the full site gets built.

Screenshot of the Agrofuturo S.R.L. under-construction landing page

Agrofuturo — "under construction" landing page

A holding page for Agrofuturo S.R.L., an agrochemicals and farm-supply company, while its full site is being built — brand-first design and a clear message that something is on the way.
