Backend Developer at NTT DATA who connected a generative AI service through LangChain and REST endpoints.

Spain
Message

At NTT DATA, I developed and maintained backend features for an existing application using Python and FastAPI, including bug fixes and issue resolution.

I built a custom LangChain integration that connected a generative AI service to the application, processing requests and responses through REST endpoints.

I also developed, manually tested, and documented REST endpoints with Postman, worked with Azure Cosmos DB through a MongoDB-compatible interface, and integrated the LiveScore API for football data and match statistics.

In my final degree project, I developed a 3D amusement ride simulator in Unity and C#, with movement systems, cameras, user interfaces, and data persistence. I also implemented audio and Spanish and English interface support, and carried out usability testing with users.
