Robert Lisita

Junior Full-Stack Developer building modern web applications and AI-powered tools.

I build modern web applications, including AI-powered tools and full-stack web systems focused on developer productivity, automation and real-world use cases. Through academic study and personal engineering projects, I have built full-stack systems covering frontend, backend services, databases and experimentation infrastructure.

The projects below include real working applications, functional MVP systems and active engineering experiments - not mockups.

Early-stage builder exploring modern web development, AI integration and scalable systems.
