Products, platforms, and experiments I have built or shaped.
These projects represent different parts of my journey: SaaS products, ecommerce infrastructure, backend platforms, education, consulting, and experiments that turned ideas into real systems.
Some projects are active products, some are founder lessons, and some represent the consulting and teaching direction of my work.
