Custom software

Custom apps, shipped on time and fast under real traffic.

From a first version to a platform with millions of users. We build web and mobile apps, the APIs and backends behind them, and real-time features like live dashboards and alerts. You see working software every week, and you keep code your team can change.

When teams call us

  • You have an idea or a spec, but no team to build it
  • Pages and APIs slow down every time traffic peaks
  • Every change to an old codebase risks breaking something else
  • Your users need live data, not yesterday's report

What we deliver

  • Web and mobile apps

    Product screens, admin tools and internal apps, designed with you and shipped in small working steps.

  • APIs and backends

    Documented APIs in PHP (Laravel, Symfony), Java (Spring Boot), Node.js or Python, with caching and queries tuned for real traffic.

  • Real-time systems

    Streaming ingestion, WebSocket dashboards and alerts that fire on their own, for data that matters right now.

  • Upgrades and rewrites

    Old frameworks and language versions upgraded step by step, with tests guarding each move.

How it runs

  1. 01

    Agree the first version

    One call and a written scope: what we build first, what done looks like and who builds it.

  2. 02

    Build in small steps

    A demo of working software every week, so you can try it and change direction early.

  3. 03

    Review and release

    Another engineer reviews every change, and critical paths are tested before anything goes live.

  4. 04

    Hand over or keep going

    You get the code, documentation and runbooks. We keep running it with you, or step away.

FAQ

Which stacks do you work in?

PHP 8 with Laravel, Symfony and CodeIgniter; Java with Spring Boot; Node.js and Python where they fit; React on the front end. MySQL, PostgreSQL, Redis and Elasticsearch on the data side.

Can you start from just an idea?

Yes. Bring the problem and who it is for. We help you cut it down to a first version worth building, then we build it.

Will you rewrite our existing system?

Rarely. We fix the parts that hurt most first and change the architecture where it pays back, so your product keeps shipping during the work.

Can you add real-time features to an existing product?

Yes. Live updates and alerts can often be added next to an existing backend, without a rewrite.
