About Raddiene
Small team.
Deep involvement.
We work close to your product, your engineers and the problem you need to solve.
Built by an engineer.
Run with the same care.
Raddiene is a founder-led team of three based in Croatia, founded in 2024. We bring hands-on backend development and production experience to businesses that need capable people close to the work.
Our founder, Mateo Ivan Radman, has been lead engineer on Slick Cover, Allianz UK’s digital-first car insurance, sold to drivers across the UK. He has been responsible for the backend behind quotes, payments and claims, AWS, the engineering team and its releases.
Since 2020 he has worked on T3K.AI’s digital forensics products. He has led the backend and releases of LEAP, its Law Enforcement Analytics Platform, built the T3K.AI CORE integration for Magnet Griffeye and developed the licensing used across T3K’s products. Raddiene has also provided L3 support engineering for Copia.io through ELEKS.
That experience shapes our approach: understand the system, make the trade-offs clear and take responsibility for the piece of work we agree.

Companies our team has worked with.
A useful extension
of your team.
We keep the working relationship simple so you can focus on the decisions that move your product forward.
Practical technical choices
We choose an approach around your existing systems, the problem and the people who will maintain the result.
Care beyond implementation
Tests, useful documentation and release considerations are part of how we approach delivery.
A focused technical toolkit.
Python, FastAPI and Django lead our backend work. SQLAlchemy, PostgreSQL, Celery, Docker and AWS support the data and infrastructure behind it, with Rust where performance or security calls for it. TypeScript, React and Next.js help us connect that work to useful interfaces.
