Duc Leanh developed core features for the finbud2024/Finbud repository, focusing on user-centric chat workflows, scalable UI architecture, and internationalization. Over four months, Duc implemented dark mode theming, agent and think chat modes, and a retrieval-augmented generation (RAG) pipeline, integrating both frontend and backend using JavaScript, Vue.js, and Node.js. The work included anonymous chat with session management and English localization to improve accessibility and onboarding. Duc’s approach emphasized modular component development, state management, and clear separation of concerns, resulting in maintainable, production-ready features that enhanced user experience, reduced latency, and supported future extensibility without introducing major bugs.

In August 2025, delivered two major capabilities for Finbud, enhancing user onboarding, engagement, and accessibility while strengthening UI consistency and localization across devices. Focused on anonymous usage patterns and English-language UX to broaden adoption and maintain a high-quality user experience.

June 2025 monthly overview for Finbud: Delivered Retrieval-Augmented Generation (RAG) pipeline integration across frontend and backend, enabling improved query relevance through vector-based retrieval. Key changes include a frontend RAG status display, a new UserInput component to toggle RAG mode, and a vector database retriever service (vectordbRetriever.js). Replaced the legacy chatRoute.js with a cohesive RAG workflow, establishing end-to-end data flow from user query to retrieval to generation to display. This work lays the groundwork for scalable, accurate responses and easier future maintenance. Major bugs fixed: No major bugs reported this month; primary focus on feature delivery and architectural refactor. Overall impact and accomplishments: Enhanced response quality and user experience, reduced latency through retrieval-augmented generation, and a maintainable end-to-end workflow. Clear separation of concerns between frontend display, input controls, and backend retrieval/generation services. Delivered as a focused, production-ready feature with a cohesive code path. Technologies/skills demonstrated: JavaScript/TypeScript, React frontend components, Node.js backend services, vector database integration, RAG architecture, frontend-backend integration, and refactoring for end-to-end data flow.
