Software Engineer Barcelona, Spain

Oriol Martín Olivé

Turning complex engineering challenges into reliable software.

Software Engineer with four years of experience building scalable web applications and production-grade Generative AI (RAG) systems. I combine a strong foundation in software and quantum engineering from UPC with hands-on delivery across modern React/TypeScript ecosystems and Python backends. Grounded in algorithmic problem-solving, clean architecture, and well-founded design patterns, I build resilient, high-performance production software.

03 / Quantum Engineering

My postgraduate capstone project.

I completed a postgraduate program in Quantum Engineering at UPC School (2025–2026); this dashboard was my final project.

Postgraduate final project2025 — 2026

Classic-Quantum Verifier Dashboard

An interactive dashboard for exploring and running the one-qubit quantum verification protocol described in “Towards experimental classical verification of quantum computation” by Roman Stricker et al. (2024).

Users can prepare a parameterized clock state, measure its Hamiltonian energy, and see in real time whether the verifier accepts or rejects the prover. The protocol lets a classical verifier test for genuine quantum behavior without simulating the full computation.
