[ Founder ][ 03 ] Hi, I'm the person you'll work with
I've been building websites and apps for ambitious brands since 2019, from Sirajganj, Bangladesh. I write the code, design the screens, and I'm the person you message at 11pm when something breaks.
No agency stack. No account managers. When you hire Explainerium, you hire me - plus a small trusted circle of designers and specialists I bring in when a project calls for it.
No project managers, no client success teams, no broken telephone. You message the person writing your code.
Most messages get a reply within hours. We're available across UK and Bangladesh business windows - somebody's awake when you write.
If a feature won't pay back, if a cheaper path exists, if your real problem is elsewhere - we say so. Even when it costs us the project.
When we hand off, you own everything. Code, content, accounts, domains. We never hold your business hostage.

Thank you for your amazing service! The whole process was not only professional but also super fun and exciting. The website turned out absolutely gorgeous - I couldn't be happier!
Working with this design team was an inspiring and intuitive process. I'm currently building an online course for my art practice, and they were able to capture not only my vision - but also the feeling behind it. They understood the mood I was going for, especially in terms of sensitivity to artistic direction.
