Computer Engineering · Backend & Systems · Applied AI · Low-level
Computer Engineering student at UAB with hands-on experience in team management, operations and technology. Resourceful, passionate and methodical — I enjoy hard problems and simple solutions.
Engineering, leadership
and real-world work.
I combine the technical rigor of engineering with the practical mindset of someone who has managed teams and operations in demanding environments.
I don't just write code: I build complete systems. From a self-managed Linux VM on Azure to CampusBot — a voice assistant with AI, face recognition and a 3D frontend — I want to understand every layer of the stack, from the kernel to the UX. This very site is served from an Ubuntu VM on Azure that I administer myself, from the bootloader to the TLS certificate.
Self-hosted server in production
Linux VM on Azure serving arnauserver.me with nginx + TLS, live monitoring and end-to-end hardening.
CampusBot — AI voice assistant
Guide robot for the UAB School of Engineering: OpenAI GPT-4o-mini, OpenCV face recognition and a 3D Three.js frontend.
Highlighted technical projects
C optimization with perf and SIMD, Azure deployments, collaborative work on GitHub.

What I've
built.
CampusBot — AI voice assistant
Guide robot for the UAB School of Engineering with face recognition (OpenCV + SFace), speaker identification (Resemblyzer), GPT-4o-mini, custom TF-IDF RAG and a 3D Three.js frontend. Multi-instance architecture over Socket.IO + installable PWA.
arnauserver.me
Ubuntu VM on Azure serving this portfolio. nginx + TLS, CrowdSec, SSH/sysctl hardening, strict CSP and local monitoring.
azure-linux-server
Docs and scripts for the full VM deployment: networking, DNS, certificates, hardening and observability. Reproducible repo.
C optimization — UAB
Performance analysis with perf and low-level optimizations: cache locality, SIMD vectorization and careful memory management.
Project management — ES (UAB)
Teamwork with GitHub, version control and collaborative planning in the UAB academic context.
Let's talk.
I'll reply.
An opportunity, a project or just plain technical curiosity — any excuse to write is a good one.
