002 — PROFILE

I build software across the whole stack and study how it breaks. My background is in electrical and electronic engineering, which means I came to programming from the hardware side — and never quite left it. That bias shows up in the work: I care about what a system is actually doing underneath the abstraction, it’s invariants and constraints.

Most of my time goes to four places. I build full-stack apps in TypeScript and
Python. I write developer tooling like compilers, scaffolders, dependency
managers, I design PCB circuits, write firmware and I do
security research, which is really the same habit aimed in the other direction.

GRIMLABS is where I put all of it. It's a lab, not a company: somewhere to
ship tools, keep build logs, and work through problems in the open.

D-01
Software Systems
Full-stack applications and the developer tooling around them — build systems, scaffolders, dependency managers.

Hardware Systems
Electrical and electronic engineering foundations — embedded work, circuits, and the layer everything else stands on.
Embedded · circuits · signals
D-04
Applied Sciences
The connective tissue: reproducibility, measurement, and writing results down so someone else can repeat them.

BUILDING
grimx a reproducible toolchain and dependency manager for C and C++ projects.
RESEARCH
pwntrack workflow tooling for triaging security findings without losing the thread.

Cross-compilation target triples, sysroots, and making native builds portable by default.
006 — CONTACT

Open to research, builds, and interesting failures.

If you are working on tooling, native builds, or security problems — or you just want to argue about a design decision — the inbox is open.
