Technical notes from production ecommerce work
These articles come from real store issues: upgrades, performance, SEO, malware and configuration. This English page is the entry point; some long-form case studies are still in Spanish while more English articles are added.
Published technical articles
The write-ups below document problems I have actually diagnosed. They are useful if you are comparing a PrestaShop developer, looking at upgrade risk, or checking how multilingual Shopify SEO was handled on a live store.
They are not marketing case studies with invented conversion lifts. They describe causes, constraints and the kind of fix that survives the next update.
What English readers can use now
This landing page is in English so international clients can find the technical notes. Some existing long-form posts remain in Spanish while English articles are added. The linked stores and the problem types still apply if you run a similar stack.
If you need the same kind of work done
A blog post is not a quote. If you have a 500 error, a slow category, a hacked WordPress admin or a Shopify multilingual SEO issue, use the quote or contact page with the public URL and the symptom.
Blog FAQs
Are all articles in English?
This landing page is in English. Some existing case-study posts remain in Spanish while English articles are added.
Do you invent client results?
No. I write about public technical problems and patterns without confidential data.
Can I suggest a topic?
Yes, if it matches a problem I have actually solved.
Will you translate every Spanish post?
Not as a bulk exercise. New English notes are added when they help international clients with the same production problems.
Have a similar production issue?
If a write-up matches a fault on your store, send the URL and the error. I reply as a developer, not as a content team.
