Slow website fix by a developer who finds the cause.

A slow website fix starts with the cause, not another plugin.

Does this sound like you?

  • The site keeps going down

    It runs for a week, then crashes under traffic, and every hour offline is a lost sale or sign-up.

  • Google flags your speed

    Core Web Vitals fail on mobile, pages load slowly, and visitors leave before they read.

  • The last developer is gone

    Nobody knows how the site was built, updates are scary, and the old plugins nobody removed keep causing trouble.

  • An update broke it

    A plugin or theme update left a white screen, a broken checkout or a layout that no longer works.

What I do for you

  • Find the cause first

    I read the error log, the plugins and the server before I touch anything, then send a short list of what is wrong.

  • Fix it without breaking your rankings

    URLs, titles and tracking stay as they are, so a repair does not cost you traffic.

  • Before and after numbers

    Mobile speed measured on the same test before and after, so you see what changed.

  • Clean up a hacked site

    I remove the malware by hand, find how it got in, close that door and help clear Google warnings.

  • Keep it healthy

    Tested updates, daily backups off the server, monitoring and a few hours of changes a month on a care plan.

How your project runs, step by step

  1. Step 01

    Study your competitors

    I look at what competitors do well and where they leave gaps, before a single screen is drawn.

  2. Step 02

    Design the UI and UX

    I design the screens myself, so what you approve is what gets built.

  3. Step 03

    Build frontend to backend

    Pages, accounts, orders, payments and the admin dashboard, built as one job.

  4. Step 04

    Launch and look after it

    Speed checked on a phone, then backups, monitoring and changes through website care.

Questions from owners of a slow or broken website

Ask something else on WhatsApp

How much does a slow website fix cost?

Single fixes start at $50 and speed fixes at $150. You get a written quote after I have looked at the site, before any work starts.

Can you fix a site another developer built?

Yes. I read the theme, plugins and errors first and send a short list of what is wrong before any work starts. You keep every login.

Will fixing my site hurt my Google rankings?

Not if it is done carefully. I keep URLs, titles and tracking as they are and check the result before and after.

What did you fix for TubeOnAI?

The site kept going down because old caching plugins had left files behind. I removed them, kept a single caching layer, rebuilt heavy layouts, and load time went from 5 seconds to 1.5.

Do you offer ongoing care after the fix?

Yes. Care plans start at $149 a month and cover tested updates, backups, monitoring and changes.
