Pioneers in Kotlin Multiplatform
Whether you’re starting a KMP project from scratch or migrating an existing app, stability is guaranteed.
We have a strong internal expertise and proven patterns that allow our partners to rely on us.
We were early adopters of Kotlin Multiplatform at a time when most teams were still skeptical about production readiness.
In addition to KMP, we work with other technologies such as:
To support different delivery needs, we offer
flexible collaboration models:

What This Looks Like in Practice
Enterprise Cybersecurity Partner
First time they worked with a long-term external engineering partner instead of ad-hoc freelancers, and they trusted our developers.
About the client
It is a software company in Greece that delivers mobile solutions for a cybersecurity enterprise client. At a critical phase of their project, they needed to scale their mobile team quickly, but any compromise in quality or seniority would have directly impacted their client relationship and delivery credibility.
For them, every engineer represents their brand in front of an enterprise customer, so technical reliability, communication, and decision-making autonomy were non-negotiable.
Our role
We joined as a technical extension of their team and provided senior mobile engineers for Android and iOS.
What changed for the client:
- They were able to keep up with delivery deadlines
- Less stress about quality slipping in front of their enterprise client
- Our engineers started contributing to technical decisions, not just implementation work
- Releases became more stable and predictable in production
- They didn’t have to constantly re-think short-term hiring or freelancer gaps
Outcome
We became a long-term extension of their delivery capacity, supporting them as an embedded engineering partner rather than an external resource provider.
