What we build
One focused studio for your store, your automation and your apps.
Start with the store. Add automation when orders grow. Build custom tools when nothing off-the-shelf fits.
How it works
From rough idea to a store that runs itself.
- 01
Idea & design
Bring your custom Figma or rough notes; we convert them into a clear scope.
- 02
Direct build
Skip slow design bottlenecks and extra fees — straight to high-speed code.
- 03
Store or app
A fast, secure build with weekly staging links and full integrations.
- 04
Automation
Orders, leads and messages move on autopilot without manual work.
The process
Four steps, no jargon, no surprises.
Share your vision or design
Tell us what you want to build. Bring your custom Figma design, sketches, or brand brief. We lock in a clear scope, timeline, and a fixed quote.
Direct to code — skip the wait
No costly Figma design fees or weeks waiting for wireframes. We code your custom Figma or jump straight to a live production build with zero design delays.
Build in weekly steps
You get a live staging link as we go. Payments, tracking and automation are connected, tested, and ready to convert.
Launch and hand over
We deploy, test on real devices, train your team, and hand over 100% full source code, production assets, and cloud accounts.
Fixed scope, written quote
You know what you get before work starts.
Zero design markup
Bring your own Figma or skip the design bottleneck to launch weeks faster.
You own everything
Full source code, production assets, and cloud accounts are handed to you.
Selected work
Real projects, real links.
Every project here is live. Results and testimonials appear only once they have been verified.
Case studies are being added. Ask us for live examples and we will share them on a call.
About
Built by one engineer who answers your messages
I'm Durjoy, a software engineer who works on e-commerce and marketing-automation systems. I started Codextrum to build stores and order automation for growing brands, working directly with the people who run them.
You talk to the person doing the work. A small team supports testing, performance and delivery.

FAQ
Questions people ask before they start.
Yes! Send a note, brief or voice message. If you already have a custom Figma design, we build it pixel-perfect. If you don't, we skip slow, costly wireframe delays and build directly on a live staging site so you see real working progress from day one.
It depends on scope. After a short conversation you receive a fixed written quote before any work begins, so there are no surprise invoices or unexpected design agency fees.
Small stores and automations are measured in weeks, larger apps in months. Because we skip unnecessary wireframing bottlenecks, projects launch significantly faster. You get a realistic timeline with weekly staging links.
Projects are founder-led. You work directly with the engineer building it, supported by a specialized engineering team for testing, performance and delivery.
Yes. Full source code, deployment assets and cloud accounts are handed over to you with 100% ownership at the end of the project.
Hosting and domains live in your own accounts. After launch you can choose an optional monthly care plan for updates and fixes, or run it yourself. Details are in your quote.
Work is split into milestones. You approve each milestone before the next begins, and the terms are written in your agreement.
We integrate gateways such as SSLCommerz, bKash, Nagad and Stripe, plus WhatsApp and Messenger flows, depending on what your project needs.
