About this gig

Hi, I'm Javier, a software engineer specialized in AI and machine learning with hands-on experience building real-world solutions, from LLM-powered agents to custom predictive models.


I offer end-to-end AI/ML solutions in Python: data preprocessing, model training and evaluation, integration of LLMs such as OpenAI or Claude into your product, and custom AI agents connected to your APIs, databases and internal tools. Every delivery includes clean, documented, production-ready code.


My process is simple: we define the problem and success criteria together, I build a working prototype and iterate based on your feedback, and you receive a tested, documented, deployable solution.


Whether you need a chatbot, a recommendation system, a data pipeline, or a custom ML model, message me before ordering so I can scope your project accurately.

I'm an Interactive Technologies student at UPV and a full-stack developer who moves comfortably between software and hardware. My work blends web development, AI, electronics, and game engines. I learn best by tackling new technical challenges, and I enjoy problems that cross multiple disciplines at once. What drives me is building things that work end to end and understanding how every piece fits together. I've delivered Unity 3D games, interactive installations, Python tools, and full-stack web apps.
