Cleaner

• Turned an opaque utility into an explainable product workflow.
• Demonstrated product judgment in a trust-critical scenario.

• Used a clear Scan -> Review -> Select -> Clean path.
• Applied risk tiers and recommendation logic rather than one-click cleanup.

• Public pages show storage attribution, risk grouping, and cleanup recommendations.
• Implemented as a real SwiftUI macOS app rather than a static concept.

• Owner / Product Engineer: turned a real cleanup problem into a transparent and safer desktop product.

• Many cleanup utilities confuse "can delete" with "should delete," leaving users without trust or clarity.

• Deletion is high-stakes, so explanation and risk grading must come first.
• The real product runs locally, so public evidence is limited to screenshots and product framing.

Most cleanup tools optimize for deletion speed instead of user trust. This product flips the order: explain first, clean second.

• Diagnose sudden storage spikes on macOS.
• Clean browser cache, dev cache, logs, and oversized downloads.
• Review risk and consequences before confirming deletion.

• A scan flow centered on storage attribution, not instant cleanup prompts.
• Cleanup candidates grouped into safe, risky, and recommended tiers.
• Item-level selection and confirmation instead of one-click clearing.

• Risk explanation appears before action buttons.
• The interface feels like a diagnosis tool, not a black box utility.
• A local desktop app is the right format for trust-sensitive operations.

• Built with SwiftUI + SwiftPM, split into CleanerApp and CleanerCore.
• Scanning logic focuses on user directories and avoids high-risk system paths.
• State management covers scan progress, selection, and cleanup reporting.

• Publicly shown as a product page and screenshots.
• The real artifact is a local macOS app build.
