Built around you, never off the shelf.
15+ years. One platform I know inside out.
I’m Yanni Sanmiguel, a freelance MODX developer in the UK. I build the high-end website, and the tools behind it, that solves the problems of your business, not anyone else’s. Then I host it and look after it myself.
Before I design anything, I learn how your business works: what slows you down, what your customers need and what your team does every day. Then I build the site, and any tools it needs, around that. No WordPress, no pre-made themes.
Cached pages, top Google scores and a multi-layer defence on the server that I run for 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 me, the person who builds your site, from the first message to launch and beyond. See the full process.
I learn your goals, your content and what slows you down today. Then I send you a clear quote and timeline.
I design the key pages, layouts, colours and components, and we refine them together.
I build on a private link you can log into any time. Fast by default, tested on real devices.
I train you so you can edit with confidence, then we go live, with backups and my support whenever you need it.
I tell you the cost before I start any work.
Designed and built from scratch around your business and your brand.
Full hosting that I administer myself, 100% tuned to run MODX and looked after by me, the developer who built your site.
Fixes, updates, new features, speed work or upgrades. If your MODX site needs it, I do it.
A website can be a full system. These are products I built and run myself: real software in production, not mockups.
Book anything. A booking platform for teachers, studios and any kind of business that wants 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, and Google prefers fast ones. I build fast sites so you are easier to find and more of your visits turn into enquiries.
I give every page 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 for me, or anyone, to change later.
Google PageSpeed Insights, mobile, home pages, run on 20 Oct 2026. Scores can move a few points between runs.
I was born in Colombia and have lived 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.
I am not an agency and I am not for everyone. Every client gets a system made for them, and my full attention.
