I like building things that are useful, technically interesting — and occasionally a little bit crazy.
My background is in Linux administration, infrastructure and systems engineering, but I'm just as comfortable diving into code when an idea deserves to become a real tool.
A federated, post-quantum-secure protocol for verifiable supply-chain provenance.
OpenWaymark is an attempt to answer a surprisingly difficult question:
Can we prove where something came from without trusting a blockchain, a central authority, or somebody's database?
It combines cryptographic signatures, append-only Merkle logs, independently verifiable proofs and federation — designed as an open protocol rather than another token or blockchain project.

🖥️ Breakthrough
A powerful terminal-native file manager and workspace for Linux and POSIX systems.
Breakthrough started with a simple idea:
The shell belongs inside the file manager — not beside it.
It combines a full embedded Bash shell with a modern TUI, panels, dialogs, context menus and terminal-based workflows.

One of my favourite ways of learning is to build something simply because it is fun.
myGoAdventure is part of that philosophy: experimenting with Go, game mechanics and terminal applications while exploring what can be built when you stop treating programming exercises as exercises and start turning them into actual projects.
Linux & Systems Infrastructure, automation, networking, security, observability and making computers do useful things.
Go From small utilities to larger systems — especially when a program should be fast, portable and pleasantly boring to operate.
Open Source I prefer building things that can be inspected, used, modified and improved by others.
Security & Cryptography Particularly where cryptography solves an actual systems problem rather than simply being added because it sounds impressive.
Terminal Software Because a good terminal application can still be one of the best interfaces ever invented.
I also write about programming, Linux, technology, Bitcoin, projects, experiments and whatever else happens to catch my attention:
It's less of a carefully curated developer portfolio and more of a record of things I've built, learned, investigated and occasionally broken.
