Independent product builder creating useful, trustworthy software.

Release evidence

The portfolio prioritizes verifiable product work: real UI, store status, local-first privacy boundaries, and release artifacts.

Chrome listing

The public Chrome Web Store URL is now used as the primary install destination.

Local-first product

The recorder does not use accounts, analytics, telemetry, a backend, or audio uploads.

Release assets

Store screenshots, privacy copy, tests, and bilingual product pages are included in the project.

Selected products

The first version includes one completed product now live on Chrome, an Edge review state, and three planned or next-up tools. Planned products describe the problem, hypothesis, risk, and validation path without implying finished software.

Product method

Research

Define the user problem, legal boundary, and first useful workflow before adding features.

Design

Turn scope into interface states, status language, privacy posture, and release constraints.

Build

Implement local-first browser and web tooling with tests, recovery paths, and predictable output.

Publish

Prepare store copy, screenshots, privacy documents, localization, SEO, and post-launch updates.

Builder profile

This portfolio is intentionally personal. It does not present a fictional company or inflate unfinished work. Each product page separates shipped evidence, review status, planned scope, and known limits.
