Iain Correia

Backend developer on a production LLM chatbot for a bond-investing platform, serving real users querying live portfolio and bond data in natural language.

Led the design and implementation of the core LangChain/LangGraph agent graph - nodes, conditional routing, and tool orchestration - as the primary owner of that component.

Collaborated with two other backend developers to integrate tool functions that retrieve and structure live financial data, bridging the LLM and the platform's database.

Built with a focus on clean interfaces, maintainability, and production-grade reliability from day one.

Contributed to key architectural decisions around state management and service boundaries

– Designed and built a complete language-learning web app solo over 2 years: game-based exercises (auto generated crossword, flashcards, memory game), user accounts, and progress tracking.

– Owned the full stack: SQLite schema design, Flask REST API, frontend, and integration of external dictionary APIs to power vocabulary exercises.

– Configured and deployed Ubuntu laptops for educational use; onboarded and supported groups of ~30 students during live sessions.
