What I'm looking for

I’m exploring embedded systems, blockchain, and WebAssembly, and I’m open to remote work.

At Quantum, I rewrote about 50,000 lines of legacy C as Rust 2021 for embedded systems managing 3,072 DALI nodes across 16 devices. The change reduced RS485 turnaround from 100ms to 10ms.

I also developed embedded Linux provisioning and time-management tools, and contributed a full-stack Leptos web app for embedded devices. My work includes Buildroot, cross-compilation, and compile-time SQL verification.

Before Quantum, I worked on public-sector technology projects at DST and enterprise web applications at Atons r.l. I’m exploring embedded systems, blockchain, and WebAssembly, and am open to remote work.
