Juang Wiantoro

Juan Gwiantoro developed and maintained core features for the mcp-getgather/mcp-getgather repository, focusing on scalable data extraction, browser automation, and frontend integration. He implemented a React and Tailwind CSS frontend, connected it to a FastAPI backend, and standardized development environments using Volta. Juan introduced browser-automation tools for Amazon and Goodreads, unified data extraction workflows across multiple connectors, and improved code quality with CI/CD enhancements and configuration cleanup. He also refactored code organization, enhanced session management, and created Faker-based mock data for testing. His work demonstrated depth in Python, TypeScript, and DevOps, resulting in more reliable and maintainable systems.

August 2025: Delivered core frontend scaffolding and UI foundation, launched an automation-assisted data extractor for Amazon purchase history, and standardized the development environment to improve consistency and collaboration. Key outcomes include a cohesive React/Tailwind/Shadcn UI frontend connected to the backend, a reusable browser-automation feature for purchase data, and a Volta-based Node.js pinning policy that reduces onboarding time and environment drift. A bug fix resolved an import issue in the Amazon history tool, contributing to more reliable tooling and faster iteration.
