In parallel, I specialize in AI-driven applications and custom web platforms, leveraging Private LLMs, Open-Source AI models (such as Llama, GPT-4All, and Mistral), and full-stack technologies such as Node.js, Ruby on Rails, Python, and Laravel. I work with startups and enterprises to implement secure, intelligent solutions that integrate seamlessly with internal workflows, APIs, and data systems.
With over 10 years of experience, I bring together technical depth, business insight, and user-first design thinking to deliver platforms that are not only technically sound but strategically impactful.
