Systems engineer working across AI, embedded hardware, and enterprise software.
I build the whole stack — from ESP32 firmware and voice pipelines to the databases, automation, and business portals that run on top of them. Eleven domains, one continuous practice.
Featured projects
Six builds that best represent the range — production portals, an AI automation pipeline, and hardware wired straight into an assistant.
Introduction
Tarunaditya
PROFILEI'm 15 years old, currently in Grade 10 at Scotspine International School, India. Alongside my studies, I work on independent projects spanning hardware, artificial intelligence, and web development.
My focus tends to be on understanding how a complete system fits together rather than a single layer of it — an ESP32 device that also needs a backend, or a web portal that also needs automation running behind it. This portfolio is a collection of what I've built so far.
Every domain, catalogued
The featured builds above are the highlights — this is the complete reference, organized by discipline.
