Hi, I’m Leo

I build open-source tools for FPGA and embedded hardware development, with a focus on making advanced workflows easier to use across vendors and toolchains.

My main project is fpgacapZero, an open-source FPGA debug and automation toolkit. It includes cross-vendor JTAG debug cores such as embedded logic analyzer, embedded I/O, and JTAG-to-AXI bridge support, along with integrations for open-source FPGA tools and AI-assisted development workflows.

Sponsorship helps me spend more time improving documentation, testing more boards and cables, expanding backend support, and maintaining the project so others can use it in real hardware projects without starting from scratch.
