3D PROJEKTAI, UAB


A professional engineering team designing and developing modern digital software solutions for the iOS platform and related technologies.

Platform Interface Application Domain core
Layered separation of concerns — dependencies point inward

Structure

Systems are built on clean architecture: a stable domain core, clear boundaries between layers, and dependencies that point inward. Each layer holds a single responsibility, so behaviour can be reasoned about, tested, and replaced without disturbing the parts around it.

Performance

Engineering work targets scalable, maintainable, high-performance systems. Performance is treated as a design constraint rather than a late correction — measured against real conditions, optimised where it changes the experience, and protected as systems grow.

Experience

Development follows a user-centered approach in which usability and stability set the standard for what counts as finished. The engineering brief is judged from the person's side of the screen: predictable behaviour, clear states, and a system that holds steady under everyday use.

Standards

The team works to modern software engineering practice and keeps to up-to-date engineering standards. Long-term technical quality is the measure of success: reliable, future-ready solutions that remain understandable and extendable years after they are written.

Evolution

Continuous innovation runs alongside delivery. New technologies are actively explored, internal processes are revised as they are learned from, and development workflows are improved so that technical excellence is sustained rather than assumed.

Commitments

  • ArchitectureClear boundaries, deliberate structure, no hidden coupling.
  • OptimisationMeasured improvement of speed, memory, and responsiveness.
  • StabilityPredictable behaviour across the whole lifecycle of a system.
  • DurabilityCode written to be read, maintained, and extended later.
