About Aitor

I am a passionate developer specialized in building cross-platform applications and cloud solutions, with over three years of experience as a Cloud & API Solution Developer. My professional background at Nationale-Nederlanden is focused on the development of Web APIs, Azure Functions, and Logic Apps within Microsoft Azure, as well as the full lifecycle management of APIs using API Gateway tools, exploring OpenAPI 3.0, OAuth, and linters like Stoplight. Notably, I have led the effort to build the ApiOps model from scratch. I work with key technologies such as C#, ASP.NET Core, and SQL, playing a critical role in projects requiring cloud design and deployment.

Currently, I am channeling my ambition into the field of AI Engineering, where I have independently developed a complete automation ecosystem. This includes building custom MCP servers in C#, orchestrating multi-agent systems with FastAPI, and implementing RAG pipelines with Chroma. I have successfully integrated these technologies with N8N and Telegram Bots to automate complex workflows like personal expense management.

Certified in AZ-900 and AZ-204, I am driven by the need to ensure I am not stagnant and can continue growing both professionally and personally. I firmly believe that self-reflection, along with strong mental and physical development, are the essential foundations for achieving any goal and delivering excellence.
