Senior🎓
Top SchoolRoman Roibu is a Senior Backend Engineer based in Berlin with 12 years of experience designing and building robust, high-performance systems across Swift, modern C++, Python, TypeScript and Rust. He blends low-latency systems work—such as real-time Solana/Ethereum ingestion and decision engines in Rust—with product-facing backend services for DeFi compliance and authentication at startups. A frequent open-source contributor, he has improved core Foundation geometry types in Swift and extended PsychoPy with Pupil Labs eye-tracker integration, showing a knack for bridging research-grade tooling and production software. His background spans embedded and latency-sensitive iOS work (BLE, ASR) to automated testing and release automation in regulated environments, reflecting strong system-level thinking and operational rigor. Always curious about AI, computer vision and reinforcement learning, he actively pursues cross-domain solutions that turn experimental research into reliable products.

Contributions summary:Roman's primary focus was on enhancing core functionalities within the Foundation Project, specifically related to geometry-related data types. They implemented the `Equatable` and `Comparable` protocols for `CGRect`, `CGFloat`, `CGSize`, and `CGPoint`, enabling equality comparisons and ordering. Furthermore, the user addressed minor inconsistencies and added new functions related to geometry computations. Their work improved the consistency and usability of these fundamental data structures.
