Work History

June 2026

1 Commits

Jun 1, 2026

June 2026 — Analog Devices no-OS: Focused on CI build stabilization for Vitis 2023/2024, delivering reliable headless CI builds and cross-version Xilinx.spec handling to reduce build failures and accelerate validation.

May 1, 2026

May 2026: Delivered code quality and tooling improvements across libiio and no-OS, with a focus on reliability, modern toolchain compatibility, and maintainability. Key outcomes include a robust non-ZSTD XML parsing fix, Versal debugging enhancements with Vitis 2025.x support and documentation, a broad migration of Xilinx tooling to the Vitis 2025 Python API (get_arch, upload, clean_build, create_project, create_fsbl), and an improved fresh-start experience by cleaning all Vitis IDE artifacts on make reset. These changes reduce release risk, accelerate debugging cycles, and position the platform for upcoming hardware and toolchain updates.
