"They rebuilt our site from a five-year-old WordPress install and the difference is night and day — load time dropped from 6 seconds to under 2, and quote requests from the site nearly doubled within the first month."
We build websites the way engineers ship software.
modernstackworks designs and hand-codes fast, maintainable websites and web apps for businesses that need something built properly — not stitched together from plugins.
Six things we ship every week.
We're a small team of developers, not an agency of account managers. Every project below is work we do hands-on, end to end.
Front-End Engineering
Hand-built, responsive interfaces — no page builders, no bloated frameworks you don't need. Just fast, accessible markup and CSS.
packagesBack-End & API Development
Databases, authentication, custom APIs, and integrations with the tools your business already runs on.
ask usE-Commerce Development
Custom-built storefronts and checkout flows — not a stock theme with a logo swapped in.
talk storesWebsite Migration & Replatforming
Moving off a slow CMS or an inherited codebase, without losing rankings, content, or uptime along the way.
Performance & Technical SEO
Core Web Vitals, structured data, and clean semantic markup — the technical foundation search engines actually reward.
Maintenance & Support
Monitoring, updates, and a direct line to the people who built your site — so nothing breaks quietly.
Three ways to ship.

Built in Granada, deployed everywhere.
modernstackworks started as two developers frustrated with how many small businesses were stuck paying monthly fees for slow, plugin-heavy sites that nobody fully understood — including the agencies that built them.
We work the way software teams do: version control, staging environments, and a real handover at the end of every project — code you own, not a black box you rent.
The studio is still based in Granada's Realejo quarter, but our clients are spread across Spain, Portugal, and increasingly further afield — hospitality groups, clinics, workshops, and retailers who needed a site that actually works.
What it's like to work with us.
"Straightforward process, clear timelines, and code we could actually hand off to our own team afterward."
"The à la carte pricing meant we could add the booking integration later without renegotiating the whole contract."
"First agency that actually explained what was slow about our old site instead of just redesigning around the problem."
