This project involved the creation of an AI-powered platform for self-understanding and self-improvement. As a team lead, I lacked the right tools to track my work and wanted to explore new technologies, prompting me to create the tools I needed. The key issue was the absence of proper tools for tracking and managing my work and understanding my behavioral patterns. As a Lead Developer, I designed the architecture and CI/CD pipeline of the app, and used Next.js, Zod, TypeScript, Tailwind CSS, and MySQL to develop this platform. The platform includes tools to track habits and moods, organize tasks, and comprehend behavioral patterns through charts and AI. While the platform is still in development, I anticipate launching a public beta for feedback and potential expansion. This project has been an enjoyable and enlightening journey, highlighting the power of collaboration and innovation.

This project was all about redesigning the frontend search functionality of a product platform. The existing search functionality was outdated and difficult to extend. The primary issue was the outdated code handling the search functionality that had become challenging to expand. My role as the lead frontend developer was to simplify and modernize the code. I consolidated the search functionality into one reusable and type-safe Angular service, employed RxJS observables and subjects to store the search state, and refactored the components that utilized the search service. The project resulted in simplified, readable, and easily maintainable code, enhancing testability and significantly reducing the development effort for building new functionalities.
