About

I design and build AI-powered applications, either as full-stack web apps (React, Next.js) or with Python-driven frameworks such as Streamlit, Gradio, and Django. My work focuses on creating smart, user-friendly solutions to help businesses grow. I also take on commissioned projects, delivering custom applications tailored to unique business needs. As a Developer Advocate at Streamlit since 2021, I’ve refined my expertise in Python, AI tools, and designing impactful apps that bridge technology and business value. With over 15 years of experience in Business Intelligence, Data Science, and SEO, I’ve worked in industries like Retail, Finance, and Travel, blending technical expertise with strategic insights to drive meaningful results. Let’s connect to explore how AI, data, and web apps can drive innovation for your business!
