We build the systems businesses run on.
Not brochure sites. ERP, hospital management, HR and payroll, point-of-sale and banking — platforms in production, built and maintained by one team across Dhaka and Toronto.
From the first conversation through to production and the years after it, the people who scope your project are the people who build it. Web, mobile and desktop — Next.js and NestJS on PostgreSQL, React Native, and Rust with Tauri — supported for as long as you run it.

Why teams choose us
Who we are
ZettaByte is a product engineering company. We build the software a business actually runs on — the system the finance team opens at 9am, the one a hospital can't admit patients without, the one that has to survive payroll day.That work started in Dhaka and now runs from two offices and two legal entities: ZettaByte Technology Limited in Bangladesh and ZettaByte Technology Incorporation in Canada. Same team, same codebase, two time zones.
Platforms, not projects
Industry systems we have already built and shipped. Yours starts from working software, not an empty repository.
Two offices, one team
Dhaka and Toronto. Overlapping hours with North America and South Asia, and a registered entity in each.
We are still here in year three
The systems we build are ones a business cannot switch off, so we staff for the long support tail, not just the launch.
Nineteen platforms. One architecture.
Every platform here is software we have already designed, built and shipped — and every one of them stands on the same foundations. That is why a project that matches one of these skips the months it takes to get a system to version one, and we spend that time on what makes your business different instead.
Choose a foundation to see everything built on it, or a platform to see what it is built from.

Why teams choose us
Four reasons, none of which are adjectives.
A head start of nineteen platforms
Most agencies begin every project at zero. We usually begin at version one — the hospital system, the point-of-sale, the payroll engine already exist and have been in production. You pay for the part that makes your business different, not for rebuilding the part that everyone needs.
Two entities, two continents
ZettaByte Technology Limited in Dhaka and ZettaByte Technology Incorporation in Toronto. You can contract locally in either market, and our working hours overlap both North America and South Asia — so a question asked at 5pm in Toronto usually has an answer by morning.
Senior people, start to finish
The person who scopes your project is the person who builds it. Nothing gets handed down to a junior after the pitch, nobody learns on your budget, and you are never passed to an account manager who has to go and ask someone else.
We are still here in year three
The systems we build are ones a business cannot switch off, so we staff for the long support tail rather than just the launch. The engineers who built it are the ones who pick up the phone when something breaks two years later, because they still remember why it was built that way.
How We Work
Six stages, three-week sprints. At the end of every sprint you get working software you can click through — not a status report.
Plan
We map what you have, what you need and what it should cost. You get a written scope before anyone writes code.
Design
Screens and flows agreed before development starts. Changing a design costs an afternoon; changing a build costs a sprint.
Build
Three-week sprints against the agreed scope, with a staging environment you can click through the whole way.
Test
Automated tests plus a human going through it properly. We find the bugs before your staff do.
Ship
Deployment, data migration, and training your team so nobody is guessing on day one.
Support
We stay on. Fixes, improvements, and someone who already knows the codebase when you need a change next year.
Our Services
Six things, done properly, rather than a list of thirty. If it is not here, we will tell you honestly and point you at someone who does it well.
Custom platform development
The big builds — ERP, hospital systems, banking, payroll. Architected to still make sense when your team has tripled.
Industry platforms, customised
Start from one of our existing production systems and adapt it. Weeks instead of months, at a fraction of a ground-up build.
Mobile & desktop applications
iOS and Android from one React Native codebase, and native desktop apps in Rust with Tauri. Our Banani DOHS app is live on the Play Store.
Web design & development
Sites and web apps that load fast, rank, and do not need a developer every time you want to change a sentence.
UI/UX design
Interface work grounded in what your staff actually do all day. We design the boring screens properly, because those are the ones people live in.
Cloud, hosting & support
Deployment, monitoring, backups, file storage, and the phone number you call when something breaks at 2am.
The stack, and why
Boring, proven and hireable. When you eventually bring engineering in-house, you will be recruiting for skills people actually have.
Next.js
InterfacesServer-rendered pages that load fast and are readable by search engines, without giving up a modern React codebase.
NestJS
APIsStructure enforced by the framework, so a backend still makes sense at fifty thousand lines and a new engineer can find things.
React Native
MobileOne codebase for iOS and Android, sharing types and business rules with the web app so a change to a calculation does not have to be made three times.
Rust + Tauri
DesktopNative desktop apps for Windows, macOS and Linux. Tauri uses the system webview instead of bundling a browser, so builds ship in megabytes rather than hundreds of them, and the Rust core handles the work that has to be fast and cannot crash.
PostgreSQL
DataYour data will outlive every framework decision on this page. Postgres is the one choice here we would still make in ten years.
Prisma
Schema & migrationsSchema changes that are reviewed, versioned and reversible, rather than someone running SQL against production by hand.
Redis
Caching & queuesBackground jobs and cached reads, so the slow work happens away from the request the user is waiting on.
Docker
DeploymentWhat we test is what you run. The same image moves from a laptop to staging to production.
Work that's running right now
Live client systems first, then demo builds you can click through. Every link opens the real thing.
Still being built
Everything else on this page was written by us. These two numbers were not — one is read from our commit history when the site is built, the other from asking the live systems whether they answer.

Messages from Our Leadership
Salman A Rahman
Chief Executive Officer
We build lasting partnerships, not deliverables. I’m proud of what we’ve shipped, and more interested in what comes next — a way of working where technology doesn’t just support a business but moves it forward. Being part of this team is something I’m genuinely proud of, and I’m glad you’re here to see where it goes.
Shams Ahmed Joy
Chief Technology Officer
At ZettaByte we don’t just build technology — we shape what comes next. Bold ideas, executed precisely, turn into systems people rely on every day. The possibilities aren’t endless in the abstract; they’re ours to build.
