About Me
Get to know the person behind the code
I'm Alan Fierro, a software engineer focused on backend systems, AI-driven applications, APIs, and data-driven products.
I enjoy building reliable systems that turn real-world problems into practical software. My work focuses on designing backend services, working with databases, and building architectures that are simple to maintain and scale, often powering AI-driven features and intelligent systems.
I'm particularly interested in integrating artificial intelligence into real products, combining backend architecture, data processing, and machine learning capabilities to build systems that are both robust and adaptable.
I also enjoy building small games and interactive systems, exploring how complex mechanics and systems design can translate into engaging experiences.
Currently, I'm studying Software Engineering at Universidad Austral while continuing to work on personal projects and improving my skills as a developer.
