About Shail Agrawal — Senior WordPress & WooCommerce Engineer
7 years, four engineering roles, one thing that hasn't changed: I build things that hold up in production.
Senior backend engineering, built on real production experience.
I'm a senior backend engineer and technical lead based in Ahmedabad, India, working with clients worldwide. For 7+ years I've built on WordPress, WooCommerce, Magento and core PHP, mostly on the parts of a site that visitors never see but businesses depend on: data flows, integrations, custom plugins and performance under load.
Tech stack
Core: PHP 8, WordPress, WooCommerce, Magento, MySQL · Integrations: REST APIs, webhooks, Zoho CRM, YouTube Data API, OAuth · Performance: Redis, object caching, query optimization, Core Web Vitals · Tooling: Git, WP-CLI, Composer, staging-first deploys
What I can help with
- API and CRM integrations that keep WooCommerce and your sales tools in sync
- Custom plugin development for workflows no existing plugin covers
- Performance work on slow stores and failing Core Web Vitals

What "senior" actually means here.
Concretely: I design plugin architecture meant to survive being maintained by someone other than me. I write REST API integrations that connect WordPress to CRMs, payment gateways, and third-party services without turning into fragile glue code. I optimize for Core Web Vitals and real database performance, not just Lighthouse scores. And I've mentored 5+ junior engineers and led code reviews, which means I'm as comfortable handing off clean documentation as I am shipping the code itself.
I also build with AI-assisted tooling — Cursor, Claude, and ChatGPT — as part of my day-to-day workflow, which speeds up delivery without changing the standard I hold the output to. Every line still gets reviewed against the same architecture and security bar I'd apply to work I typed by hand.
How I approach freelance work.
I hold a full-time technical leadership role, and I'm upfront about that. Freelance is how I take on scoped, high-leverage problems that don't fit into a 9-to-5: a performance audit, a plugin rebuild, a stuck integration, an architecture review before a big migration.
Because I'm selective, every project gets senior-level focus, clear written communication and realistic timelines. I work async-first with updates you can read on your own schedule, which suits clients in the UK, Europe, the US and Australia.
