software development · sombor, serbia

Software from people you’ll know by name.

Five engineers who worked together for years before there was a company to put on the invoice. We build the systems businesses run on, and we stay to run them.

Continuity

Not a startup that appeared last year. The five of us have worked together on the same client platform for six to eight years each. The company just made it official.

People, not resources

You won’t be handed to “a resource”. The person who scoped your project writes the code, and picks up the phone when you call.

Serious, not sterile

The work is rigorous; the conversation isn’t. Plain language, honest estimates, and we tell you early when something won’t work.

01 · who we are

The team came first. The company came later.

Localhost Development started the way most durable things do: people who worked well together kept doing it. Long before there was a company registered in Sombor, the five of us were designing and building software side by side, and living with the consequences of our own decisions.

That last part matters. When you’ve maintained your own code for years, you write it differently. You pick boring technology on purpose. You document the thing nobody will remember. You say no to the clever solution, because you know who’ll be debugging it at two in the morning.

We’re a small company by design. Small enough that you’ll know everyone by name. Experienced enough that you won’t need to.

Engineers. Senior only.

02 · how we work

We solve your problems as if they were ours.

01

Same people, start to finish.

The engineer who scopes the work builds it and maintains it. No hand-off to a different team once the contract is signed.

02

We say it early.

We’ve done this long enough to know when something won’t work. You’ll hear it before it costs you money, not after.

03

Plain language.

Written estimates you can read without a translator. Updates in sentences, not dashboards. No synergy, no next-gen, no disruption.

04

We stay.

Most of our work is long-term. Systems we built years ago, we still run. Whoever takes over from you will find us still here.

What we do

Most clients end up needing all four, and stay for years.

  • Web applications

    Internal tools, customer portals, the system your company actually runs on. Built to be maintained, not just launched.

  • Mobile apps

    iOS and Android, usually as the front end of something bigger we’re also building.

  • Architecture & consulting

    When you’re deciding how to build something, or whether to. We’ll tell you if the answer is no.

  • Maintenance & support

    Systems don’t stop needing people once they’re live. The same people who built it keep it running.

03 · work

Work that is still in production.

Most of our work is with one client, on one platform, for years at a time. This is what that looks like.

worked with

Continental · automotive

A fleet tire service platform, modernised while it kept running

  • 6 to 8 years on it, each of us
  • New frontend platform since 2022
  • Angular · Java · Spring Boot · Kubernetes

The system Continental’s tire service network uses to record work on commercial vehicle fleets, handle orders and invoicing, and track casings. A large Java platform with two decades of history, tied into the company’s ERP, and in daily use across the network.

  • A new user interface. We designed and built the Angular frontend platform from scratch (shared component library, design system, Storybook, end-to-end tests) and have been moving the product onto it since 2022, screen by screen, with the system in use throughout.
  • A database migration, data and all. The platform now runs on a different database engine, with its full history intact. We did the same again on the casing system below.
  • A backend that stays supportable. Framework and runtime upgrades measured under production-like load before they go anywhere near production, and a REST API for the client’s external integrations.
  • A test safety net that runs on every build. End-to-end, API and load tests, including load tests against a database seeded with millions of rows.
  • Containerised and deployed on Kubernetes through automated release pipelines.

Continental · casing management

A casing management system, brought onto a modern platform

  • 2026
  • Java · Spring Boot · Kubernetes
  • With two junior engineers we mentor

The system that manages tire casings from collection through evaluation to settlement, tied into the company’s ERP.

  • Containerised and moved onto the client’s Kubernetes platform, with automated builds and releases.
  • Modernised the framework and the database underneath it, historical data included.
  • Reviewed the whole codebase and wrote the roadmap for the rest of the modernisation.
  • Delivered with two junior engineers we mentor. Growing people is part of the job.

NTT DATA · IT services

Projects for NTT DATA’s clients

Before the company had a name, the same five people delivered projects for NTT DATA’s enterprise clients. Same team, same way of working.

04 · the team

Five people. You’ll remember the names.

05 · contact

Talk to a person.

No forms, no ticket numbers. Write or call and you’ll reach Jovan: one of the five, not a sales desk.
