Senior WordPress & WooCommerce Developer for Hire
I'm Shail Agrawal, a senior backend engineer with 7+ years of production WordPress, WooCommerce and PHP work. I build the parts off-the-shelf plugins can't handle: custom plugins, CRM and API integrations, and performance fixes that move real Core Web Vitals numbers.
Shail Agrawal · WordPress & WooCommerce developerNot a themer. A backend engineer who specializes in WordPress.
Most WordPress freelancers are strongest on the front end: themes, page builders, layout. That's valuable work, but it isn't what breaks when a business grows. What breaks is the backend. Orders stop syncing with the CRM, checkout slows down under load, and a plugin conflict takes the store offline on a Friday night.
That's the work I focus on. As a freelance WordPress developer, I take on scoped, senior-level engineering problems for store owners and agencies in the US, UK, Europe and Australia. You get architecture decisions explained in plain language, code built on WordPress and WooCommerce hooks (never core edits), and a clear written scope before any work starts.

How working with me works
- Discovery call (20 min): what's broken or needed, and what "done" looks like.
- Written proposal: scope, timeline and cost. Fixed price where the work is well-defined.
- Build in staging: progress updates, never changes on your live site first.
- Review & launch: you test, I fix, we deploy together.
- Handoff + 14 days of fixes: documentation and a support window included.
Time zones: I work async-first with clear written updates, with overlap hours for UK/EU mornings and US evenings. Read the full process →
Why clients choose a senior freelancer over an agency or marketplace
- You talk to the engineer who writes the code. No account managers, no handoffs.
- Senior judgment on small projects. A 2-week integration gets the same architecture thinking as a 100K-user platform.
- Transparent pricing. Fixed-scope quotes and published starting rates. See how pricing works.
- Selective availability. I take on a limited number of projects, so each one gets real focus.
