Selected work

Current projects with their own voices.

The common thread is not subject matter. It is the way the work is made: clear framing, distinct identities, and enough care that each project earns its own home instead of being buried inside a generic portfolio dump.

Finite time, visualized

Poster-like planning for seasons, milestones, and a finite number of weeks.

Current project

4000 Weeks

Private preview

A poster-like life-in-weeks planner that turns finite time into something editable and easier to act on. Reflective rather than productivity-first, with its own editorial voice.

Web appReflective planning
  • Maps life in weeks, seasons, and milestones.
  • Keeps planning data in the browser and supports export workflows.
  • Currently staged behind a preview lock while the product sharpens.

Guided breathing, external sensors, and local-first HRV sessions.

Current project

A precision-oriented Android HRV biofeedback app for resonance breathing training. More technical and sensor-driven than a generic breathing timer, with local-first data handling.

Android appHRV biofeedback
  • Built for Android with external heart rate monitor support.
  • Uses local-first data handling instead of cloud-first storage.
  • Landing page is live while Google review and beta access continue.
