This page is a concise status view of active and recently documented work. It links to public pages, screenshots, source snapshots and case studies while keeping private repositories and early-stage limitations clear.
Selected current work
Each status is intentionally narrow. Public source is linked only where a public repository actually exists.
A private Android prototype exploring low-friction personal check-ins, clear interface wording and local-first design thinking.
Public: project note, prototype screenshots, documentation repository and a privacy-reviewed source snapshot. Not presented as a medical product or public service.
A local desktop SDR prototype covering spectrum display, receiver diagnostics, scanner workflow experiments and careful capability boundaries.
Public: project note and screenshots. The working repository remains private, and the page makes no product-availability claim.
Local-network printing from Android through Windows or Linux agents, with real application captures, documented tests and a successful public verification run.
I have confirmed it works on my own printer. The project note separates that check from mock-mode screenshots and explains the remaining compatibility and release limits.
A browser utility for drafting evidence-aware project build notes with status, proof and limitation prompts.
Public: working browser tool and source repository. It produces draft notes for review; it does not verify claims automatically.
Accepted contributions
Alongside my own projects, I contribute focused fixes to other open-source repositories. These three changes were reviewed and merged by their maintainers. Dates below are UTC.
These are individual code or documentation contributions, not employment, partnerships or endorsements. The linked pull requests record the exact changes and review history.
Documentation surfaces
The three owned sites have different jobs, so visitors can move from identity to project context without reading duplicate biographies.
