Products & Services
AI-powered job-hunting assistant that automatically discovers jobs, scores matches, generates tailored CVs and cover letters, and provides visibility into the application pipeline. The official site labels it free and a personal side project.
Open-source, local-first Agent Skill for Claude Code and Codex. It scans local session folders, converts safe aggregates from coding history into a private localhost dashboard with a coding overview and four insights, and supports intentional export without sending transcripts to the cloud.
A set of four Claude Code skills that helps AI-generated Figma work stay compliant with a design system through token maps, component registries, and a three-step preflight process.
An open-source skill that reverse-engineers a website's visual taste into design tokens, rationale and trade-offs, with exports for tools such as Claude Code, Cursor, and Windsurf.
Market Position
Lin's work is positioned as a solo-builder portfolio rather than a conventional venture-backed company: JobFlow is a free, lightweight alternative to job-search suites such as Huntr and Simplify, while Coding Wrapped differentiates from coding-analytics products such as WakaTime by focusing on private, local, qualitative reflection on AI-agent sessions. The design skills differentiate by emphasizing design rationale, system compliance, and shipped-looking page structure rather than generic AI-generated output.

Independent product designer, researcher, and builder

Founding Story
JobFlow is described on its official site as a personal side project built to help job seekers move faster and stress less. Lin's broader independent-work direction is to turn personal experience with AI agents into practical, private, open-source tools; Coding Wrapped was motivated by wanting to see how Lin actually worked with Claude Code and Codex rather than only seeing the finished projects.
