Esvin Joshua._
I build production-minded Next.js websites, Flutter apps, cloud backends, and AI products where reliable systems meet sharp user experience.

WHO
Full-stack systems,
from idea to launch.
I'm Esvin Joshua, a full-stack developer from India building production-minded web, mobile, cloud, and AI systems. My work sits at the intersection of Next.js interfaces, Flutter apps, Firebase and Supabase backends, cloud infrastructure, and LLM-powered product experiences.
I care about shipping useful software: fast frontends, reliable APIs, practical AI workflows, and products that feel clear to the people using them. Recent work includes campus platforms, educational AI tools, networking products, custom version control systems, and freelance websites for real organizations.
