NUZM builds back-end systems in Elixir, Go, Scala and Clojure. These are chosen where a mainstream stack would work but not well enough: systems that must stay up under load, handle many connections at once, or encode rules complicated enough that catching errors at compile time is worth the extra effort.
When a specialist language is worth it, and when it is not
It is worth it when an outage costs more than the engineering does, when concurrency is the requirement rather than a detail, or when the domain rules are elaborate enough that a type system pays for itself.
It is not worth it for an ordinary business application, and it deserves a second thought if your own team will maintain it. Developers in these languages are harder to hire in Pakistan than PHP or JavaScript developers, and that cost is inherited by you at handover rather than paid by us during the build. We will say so before you commit rather than after.
The four languages, and what each is for
- Elixir: the BEAM virtual machine, built to keep telephone exchanges answering while parts of them failed. For messaging, live dashboards and anything holding thousands of connections open.
- Go: a single binary with no runtime to install, starting in milliseconds. For APIs, background workers and tools where predictable speed and simple deployment matter more than expressiveness.
- Scala: a strong type system on the JVM, so whole categories of error are caught while the code compiles. For data-heavy back ends and existing Java estates.
- Clojure: functional, on the JVM, built around immutable data. For transformation pipelines and rules engines whose logic changes more often than their structure.
What comes with every system
Observability from the first commit rather than after the first incident, because a system designed to survive faults has to let you see the faults it survived. Load testing against realistic figures before launch. Graceful shutdown, so a deploy does not drop the requests that were in flight. And a documented build, since an undocumented one stops working the week its author leaves.
Questions about custom systems
Who owns the code and the accounts?
You do, on final payment. That includes the source code, the repository, the domain, the hosting account and every third-party account created for the project. Handover is a step in the project, not a favour asked for afterwards.
What technologies does NUZM build with?
Web: WordPress, custom PHP and the MERN stack (MongoDB, Express, React, Node). Back-end systems: Elixir, Go, Scala and Clojure. Mobile: Flutter, native Android and cross-platform builds. AI and automation: n8n, Make, custom chatbots, and model fine-tuning including XTTS for voice. The stack is chosen after the requirement, not before it.
Can you take over a project someone else started?
Often, and the first step is always an assessment rather than a quote. We look at the code, the hosting and the accounts, and tell you whether it is cheaper to continue or to rebuild. Sometimes the answer is rebuild, and saying so early costs you less than discovering it after three months of patching. Before anything else you will need the repository, the hosting login and the domain registrar account, and if the previous supplier holds any of those, getting them is the real first task.
What if our requirements are not clear yet?
That is normal and it is a reason to start, not a reason to wait. The first conversation is about the process you want to fix rather than the software you think you need, and quite often the map that comes out of it removes a step or two before anything is built. What we will not do is quote a fixed price against an unclear scope: that quote would be wrong, and both of us would find out in month three.
How do you handle our passwords and data?
Access is requested per system, in your name, with the least permission the work needs, and it is handed back or revoked at the end. Passwords are not emailed and are not kept in a document. Live customer data is not copied onto a developer machine; work is done against a reduced or anonymised copy where real data is not required. If a system cannot be accessed any other way, we say so rather than quietly working around it.
Tell us what has to stay up
Describe the load, the failure you cannot afford, and what exists already. You get an honest answer about whether a specialist stack is justified.
