What I actually built.
The problem each one solved, what got built, and where it honestly stands today — including the ones that never left internal use.
BrainBox
Most AI apps ship your data to a server you don't control.
An offline-first AI lifestyle app — on-device LLM chat, personas, habit and routine tracking, journaling, and a gamified wellness engine, all running with zero cloud dependency.
Autonomous Research & Web Generation Pipeline
Competitive research and brand-accurate websites both take days of manual work.
A pipeline that ingests PDFs and slide decks, runs automated competitive analysis, extracts a brand's type and palette, and generates a brand-accurate website — with LLM providers hot-swapped mid-pipeline.
Android Intent & Automation System
Repetitive phone tasks — settings, messaging, reservations — shouldn't need a human every time.
Kotlin automation built on Android Accessibility Services: natural-language 'semantic notes' become multi-step routines, plus automated messaging and IRCTC-style reservation navigation.
Automated Meeting Intelligence
Meetings produce decisions that die in nobody's notes.
Gemini-powered diarization and sentiment analysis that turns a recording into an auto-generated PRD and distributes tasks across QA, Dev, and DevOps.
instauser-understanding
Creators guess at their audience instead of knowing it.
An AI system that maps audience behavior and archetypes into insights a creator can actually act on.
Synergy
College students learn in isolation with no shared platform to collaborate across courses.
A collaborative learning platform for colleges — pitched live at a Tamil Nadu Startup event, where it won a prize.
Drug Analysis System
Reading and comparing molecular structures by hand doesn't scale.
A SMILES (Simplified Molecular Input Line Entry System) parser and analyzer, built from scratch in .NET.
That's the featured seven — sixteen-plus applications shipped in total, several on the Play Store, including a college game and a YouTube spam-comment finder-and-remover bot nobody asked for but everybody's inbox needed.
