I build
cores & accelerators
that ship.

Not just papers — silicon. I've taken a custom Cortex-M0+ compatible core, a RISC-V-controlled transformer accelerator, and an SNN NPU from RTL to tape-out. I care about the same things you do: IPC, power, area, and whether the dense-fallback path is deterministic.

I've designed a core, not just used one

ARMuP: Cortex-M0+ compatible custom ISA with µSIMD instructions I specified, implemented, and taped out on SK keyfoundry 130nm.

µARCH

Accelerator microarchitecture end-to-end

Sparsity-aware transformer accelerator with zero-skip datapaths and a RISC-V controller doing runtime clock gating — Samsung 28nm, 2025.

PPA

Power is my first-class metric
