Computer Science MSc with interests across systems, software engineering, AI, and security. I build compilers, backend systems, ML/RL projects, and security tooling. Based in Switzerland.
- Systems and software engineering: compilers, OS/networking foundations, performance-minded development
- AI/ML: multimodal learning, reinforcement learning, PyTorch/Gymnasium
- Security: software supply chain security, secure SDLC, AppSec
- Backend/data systems: TypeScript/Node.js, REST, MQTT, MongoDB, InfluxDB, Docker
- DynamicCBOM — runtime CBOM extraction via eBPF/bpftrace, generates CycloneDX 1.6 CBOMs + evaluation charts
→ https://github.com/SEG-UNIBE/DynamicCBOM - rl-elevator — event-driven Gymnasium environment + FIFO/LOOK baselines + RL agents + evaluation/visualization pipeline
→ https://github.com/william-dan/rl-elevator - LingoDB-CSE — undergraduate thesis prototype: multi-query optimization via common sub-join elimination + hash multi-map reuse
→ https://github.com/william-dan/LingoDB-CSE - SysY2022-ARMv7-Compiler — optimizing compiler targeting ARMv7, with SSA-style middle end + practical backend & reg allocation

- 📄 When Gradient Optimization Is Not Enough: Dispersive and Anchoring Geometric Regularizer for Multimodal Learning — arXiv:2601.21670
https://arxiv.org/abs/2601.21670 - 🏆 ICPC SWERC 2025 — selected to represent University of Bern (team contest)
- 🏆 Huawei BiSheng Cup (National Compiler Design Competition) — optimizing compiler in C++ targeting ARM
Security / Platform: AppSec • DevSecOps • OAuth2/JWT • Linux • Docker • Nginx • (runtime tracing) eBPF/bpftrace
Systems: C/C++ • compilers/tooling • networking • performance mindset
Backend / Data: TypeScript/Node.js • REST • MQTT • MongoDB • InfluxDB • testing (Jest)
ML (selective): PyTorch • RL (Gymnasium / PPO)
I’m open to software engineering roles across systems, backend/platform, AI-adjacent, and security-related domains.
