YiKai T.

I build and maintain SaaS applications, admin dashboards, and customer portals using TypeScript, Vue/React, and Node.js. I work with founders and product teams on new applications, ongoing feature development, and improving existing systems. My experience includes six years as a core frontend engineer on School365, a management platform used by more than 20 schools. I worked with backend, product, and QA teams to maintain complex workflows through years of changing requirements and releases. I also independently built Raneen Village, owning its Vue interfaces, NestJS APIs, database design, role-based permissions, reporting, and production deployment. For PaperFlow, an AI writing application, I developed background processing, document editing, and an admin dashboard for managing generation tasks and usage. I can help with user accounts and permissions, approval workflows, content management, reporting, API integrations, and background jobs. My work covers both the interfaces people use and the backend processes that keep the application running. When joining an existing project, I review the relevant workflows and code, agree on a manageable first delivery, and test the changes before handoff. I keep you informed about progress, blockers, and decisions that affect scope or cost. Core tools: TypeScript, Vue, React, Node.js, NestJS, Express, MySQL, PostgreSQL, Redis, and Docker. Tell me about your application and what you need to build or improve. I’m available for ongoing development and maintenance.
