Open-source tools for the Qiskit ecosystem

I build open-source quantum computing tools, mostly for the Qiskit ecosystem. My background is in mathematics — number theory, graph theory, and formal proof in Lean 4 — which tends to show up in how I approach circuit construction and error mitigation: as things to prove correct, not just get working.

Two projects are live so far: Qiberis, a backend-agnostic circuit API spanning Qiskit, Cirq, and PennyLane. Qiskit SQD Dashboard, a live convergence widget for sample-based quantum diagonalization. Both are verified Qiskit Ecosystem members.
