About me

Building in public,
shipping as open source

I'm Bipul Kumar — the developer behind BlazeNXT. I spend my time turning ideas into working products: Telegram bots that run 24/7, AI assistants that listen and talk, Flutter apps for phones and TVs, and web platforms built with React & Next.js. Every project lives in the open on GitHub — free to use, free to fork, free to learn from.

  • Python is my home turf — bots, automation, AI & backend tooling
  • Full-stack web with React, Next.js, TypeScript & Tailwind
  • Flutter apps that run on Android phones and Android TV
  • Go services & Telegram bots when performance matters

Bots & Automation

Telegram bots in Python & Go — music bots, refer-&-unlock systems, API admin panels and multi-API SMS forwarders, deployed on Docker & VPS.

AI Assistants

Voice-driven AI systems with OpenAI & Gemini brains, speech recognition and text-to-speech — wired into real system automation.

Apps for every screen

Flutter apps for Android mobile and Android TV — from ad-free music streaming to a D-pad friendly TV web browser.

Privacy & Security

Zero-knowledge tools like vault100 — client-side AES-256 & ChaCha20 encryption where your data never leaves your device.
