15+ years. One platform. Total control.
I’m Yanni Sanmiguel, a freelance MODX developer in the UK. I build your site, host it and look after it, so it stays fast, secure and easy to edit.
Custom MODX sites designed around how your team publishes. No WordPress, no pre-made themes.
Cached pages, top Google scores and a multi-layer defence on the server that hosts your site.
MODX 2 to 3 upgrades, broken extras, rebuilds that never finish. I find the cause, fix it and tell you the price before I start.
Your site runs on hosting that I administer myself, built only for MODX sites and 100% tuned to run them. If something goes wrong you talk to me, not a call centre. Send a WhatsApp and I take care of the rest.
You talk to the person who builds your site. See the full process.
We map your goals, your content and what slows you down today. Then I send a clear quote and timeline.
I design the key pages, layouts, colours and components, and we refine them together.
Built on a private link you can log into any time. Fast by default, tested on real devices.
Training so you can edit with confidence, then go-live, backups and support when you need it.
You always know the cost before work starts.
Designed and built from scratch around your brand.
Full hosting that I administer myself, 100% tuned to run MODX and looked after by the developer who builds on it.
Fixes, updates, new features, speed work or upgrades. If your MODX site needs it, I do it.
MODX is a solid base for full systems too. These are products I built and run myself, real software in production, not mockups.
Book anything. A booking platform for teachers, studios and small businesses who want to take reservations and payments online without a heavy booking suite.
Each business gets its own space where members book classes and services, pay a deposit or use credits, and manage their bookings. Owners add the booking widget to their own site, send courtesy places and get an installable app with notifications.
A real-time IoT platform. Devices connect securely over MQTT, their data is stored as time series and shown on live dashboards, and a rules engine reacts to readings the moment they arrive.
It is multi-tenant, so each customer sees only their own devices, and it includes user management and a support ticket system. The portal itself runs on MODX.

Built by me, used on my own sites.
Tools I build for MODX and use on my own sites. Both are available from monsterextras.ysanmiguel.com.
A full-page cache for MODX. The first visit builds the page, then every repeat visit is served as a ready-made static file, without waking PHP or MySQL.
Your pages load faster, your Google scores improve and your server stays calm when traffic spikes.
A smarter search inside the MODX Manager. It understands prefixes and forgives typos, so you and your team find what you are looking for on the first try.
Less time hunting through trees and lists, more time getting the work done.
Every site I build is measured with Google PageSpeed. These are real mobile results from live MODX sites.
Google scores every page from 0 to 100. Anything from 90 up is green. This is the average of the three sites below.
Removals company in York since 2008, with 482+ five-star reviews. A MODX site that has to load fast and rank for local searches.
Online yoga classes with bookings, class credits and payments, all on MODX.
A creative studio website built on MODX 3.2 and launched in October 2026.
People leave a slow site. Google also prefers fast ones, so a fast site is easier to find and more likely to turn a visit into an enquiry.
Every page gets a clear title, one main heading, sensible sub-headings, descriptive image text and tidy links. Google then knows what each page is about and shows it to the right people.
A website has three simple parts. HTML is the content and structure, CSS is how it looks and JavaScript is what it does. I write each by hand, keep them separate and small, and load only what a page needs. Less code means a faster, safer site that is easy to change later.
Google PageSpeed Insights, mobile, home pages, run on 20 Oct 2026. Scores can move a few points between runs.
Born in Colombia, living in Greater Manchester since 2013. I have worked remotely since 2008 with clients across the UK, the USA, Costa Rica and Colombia. I choose MODX because it stays out of the way: secure, flexible and fast when it is set up well.
