Radu-Stefan Popa

Software engineer and Computer Science student at the University of Bucharest.

I work across C#, TypeScript, C++, Python, and Java. I like projects that let me work across the whole system: data model, backend, user-facing behavior, deployment, and the awkward edge cases in between.

Recent work includes:

  • debugging multithreaded C# software used in ophthalmic surgery systems;
  • prototyping an internal assistant for device-log triage and related-incident retrieval;
  • working with Prof. Radu Tudor Ionescu on extending PQPP (CVPR 2025) across multiple languages;
  • tutoring algorithms and data structures at the University of Bucharest.

Selected projects

  • AI Arena — live comparison arena for nine OpenAI, Anthropic, and Google models, with parallel inference, anonymous voting, AI judging, and per-round latency and cost tracking. Live app
  • 3D Game Engine — C++23 engine with dynamic-navmesh A* pathfinding, state-driven NPCs, Bullet physics, and raylib rendering.
  • Social Media Platform — ASP.NET Core and Next.js application with 65 REST endpoints, private follows, groups, chat, and Gemini-backed moderation.
  • QR Toolkit — Python QR encoder and decoder with finder-pattern detection, masking, bitstream parsing, and Reed-Solomon correction.
  • Banking System — Java/JDBC application with repository-based persistence, transactional transfers, account and card workflows, reporting, and audit logs.
  • OS Storage Management — x86 assembly implementation of allocation, lookup, deletion, and defragmentation for one- and two-dimensional storage layouts.
