Free audit
Get a free audit of your site
Give me the address. I look at it myself and send back what is slowing it down or breaking it, and the three fixes I would do first.
- Mobile speed and Core Web Vitals, measured with Google's own tool
- Plugins, theme and caching: what is clashing or doing nothing
- What is stopping search engines reading the site
No cost and no obligation. You get the findings whether or not we work together.
Paste your site address and I will lay out the audit.
Process
How I work
- Step 01
Find the cause
I test the site, read the errors and check what changed before I touch anything.
- Step 02
Fix the root
One clean fix where the problem lives, not a patch on top of it.
- Step 03
Measure it
Before and after numbers from PageSpeed Insights that you can check yourself.
- Step 04
Hand it over
You get notes on what was done, so the next change does not undo it.

Can you fix a WordPress site that keeps going down?
Yes. I start by finding the cause, not by adding another plugin. On TubeOnAI the downtime came from leftover cache plugin files clashing with the host's own speed plugin. I removed them, kept one caching layer, and load time went from 5 seconds to 1.5.
What does a WordPress developer like you take on?
All of it, front end and back end. That covers custom themes, custom features, plugin development, WooCommerce and payments, integrations with other tools, security and speed. A build from a Figma design is one kind of project, not the only one.
Do you only work with WordPress?
No. I also build custom web products. Wrkbase, a team management platform with an AI agent, is my own product: I designed it, built the software and built its website without WordPress.
What does a WordPress speed fix involve?
I measure the site with PageSpeed Insights, then work through what the report shows: caching set up once and properly, unused CSS and JavaScript removed, images resized and served in modern formats, and heavy page-builder layouts rebuilt. You get the before and after numbers.
How do you measure the result?
With Google PageSpeed Insights and Core Web Vitals, on mobile, before and after the work. You see the same numbers I do, and you can run the test yourself at any time.
Do you offer ongoing maintenance?
Yes. I still maintain and update Tabby's website after building it, and I can do the same for a site I have built or fixed for you.
Can you add AI to my product or website?
Yes. I build AI agents that take actions inside a product, connect language model APIs to sites and apps, add chatbots to WordPress, and automate repeat work. The agent inside Wrkbase, my own platform, is the worked example.
How much does a project cost?
It depends on the scope, so I look first. Send me the site or the brief, I tell you what I would check or build and in what order, and you get a written quote before any work starts.
Do you work with companies outside Bangladesh?
Yes. I work remotely from Dhaka. Tabby is a US product, and I have built for clients in Denmark and the UK.
