FAQ
Common questions, direct answers.
Showmik Hassan is a senior web developer based in Dhaka, Bangladesh, with five years of building 150+ production WordPress sites. Teams in the US, UK and Europe work with Showmik Hassan for custom WordPress engineering, headless Next.js builds and performance work.
Two ways: hire Showmik Hassan directly as a senior web developer for hands-on builds, or work with Showmik Hassan's agency when a project needs a bigger team. Either way you get clear weekly updates and code you fully own.
A 30-minute discovery call to understand the outcome you need. If it's a fit, you get a written scope, fixed-cost or weekly retainer estimate, and a timeline within 48 hours. After kickoff: weekly written progress notes, a deployable preview every Friday, GitHub access from day one.
WordPress is the centre of gravity, but most engagements include a JavaScript layer too — Astro, Next.js, or a custom React island. Headless WP via WPGraphQL is the most common shape. I've also shipped pure SPA work and standalone plugins.
Currently taking on new work. I run two engagements at a time max — no juggling six clients badly. Lead time for a new project is usually 2–4 weeks.
Yes, fully. Code lives in your GitHub or one I transfer to you on day one. No proprietary tooling, no vendor lock-in. If we write a custom plugin, you own that too — including the right to fork or open-source it.
Two revision rounds per milestone are baked into fixed-cost projects. Bigger scope changes get an additional written estimate before any code moves — no surprise invoices.
A 30-day warranty ships with every fixed-cost project, no charge — anything broken on launch day gets fixed. Beyond that, ongoing maintenance is the Partner retainer (see Pricing).
Dhaka, Bangladesh — GMT+6. Most of my clients are in EU or US, so I overlap with afternoon hours both directions. Async-first by default; calls scheduled around your timezone.
