At Calaxy, a blockchain-based social media app startup, I specialized in front-end development and quality assurance, contributing heavily to the development, testing, and release of a large scale Progressive Web App (PWA). My work spanned feature implementation, code review, QA leadership, and internal tooling.
* Developed, tested, and maintained frontend features using Vue and TypeScript.
* Reviewed pull requests, identified regressions, and contributed fixes across a large-scale codebase with strict quality standards.
* Defined and maintained 2,000+ functional acceptance criteria based on design specifications, significantly improving implementation consistency and product quality during the transition from native mobile to PWA.
* Led end-to-end QA efforts across the entire PWA, from initial issue documentation to production signoff, ensuring consistent quality and functionality when deployed.
* Contributed to team-wide sprint planning efforts by helping review issue reports and discuss prioritization with engineers.
* Owned the review of all end-user bug reports, independently reproducing issues, identifying root causes, and implementing frontend patches.
* Built, tested, and maintained internal and open-source tools—including a Social Token Leaderboard and Token Distribution Tool—using TypeScript and REST APIs, with custom UIs implemented from Figma designs.
