Bitcoin wallet reproducibility reviewer, build forensics operator, and maintainer of verification tooling around WalletScrutiny.
My work focuses on one question: can users independently verify that the Bitcoin wallet app or device they install corresponds to the source code and release claims made by its developers?
That means reviewing wallets, tracing build systems, writing reproducibility scripts, comparing binaries, documenting failure modes, and publishing evidence when claims do not match artifacts.
As of the January 2026 WalletScrutiny snapshot, I was listed as author on
3655 of 6538 Bitcoin-related app/device pages: 55.90% of the tracked
WalletScrutiny corpus at that point.

That work spans Android wallets, iPhone wallets, bearer instruments, hardware wallets, desktop wallets, and other Bitcoin-related custody tools.
As of July 8, 2026, my local WalletScrutiny archive contains 286
reproducibility verification and endorsement report files for Bitcoin apps and
devices.
Desktop 166
Android 105
Hardware 12
Endorsements 2
Unsorted 1
Total 286
These are hands-on verification records: build runs, artifact comparisons, reproducibility findings, and endorsement checks where I reviewed and compared the underlying evidence.
As of July 8, 2026, my authored commits in the official WalletScrutiny GitLab history total:
Total unique commits in scope: 10076

therobotbay.com is a work-in-progress robotics and automation project. Development is currently stalled by lack of funding, which limits hardware procurement, controlled test time, and sustained engineering focus.
With dedicated funding, the project could move from prototype work into structured benchmarking: repeatable test setups, performance measurements across comparable systems, cost/capability analysis, and published data comparing robot platforms, components, and automation workflows.

- Evidence-first software forensics
No assumptions. Only evidence.
If a wallet claims to be open source, reproducible, or self-custodial, that claim should survive contact with the source tree, build instructions, release artifact, and binary diff.
