AI/ML Engineer • Systems Builder • Deep-Tech Explorer

I build things end-to-end — from custom operating systems and neural signal decoders to production ERP systems and autonomous agents. My interests sit at the intersection of AI, embedded systems, aerospace, and neuroscience, and I think in first principles across all of them.


⚡ About Me

  • 🎓 B.Tech in AI & ML — final semester exams completed, currently building & job-hunting
  • 🏭 Built a production ERP system at Fresco Global handling 500+ daily orders with an ML-based task-assignment engine
  • 🧠 Working on a P300 EEG Brain-Computer Interface — 88% cross-subject accuracy on BNCI2014009
  • 💻 Built HelixaOS — a custom x86 operating system from scratch (bootloader → protected mode → GDT/IDT → VESA graphics)
  • 🤖 Building AgentOS — a modular Android AI agent app with on-device tool orchestration
  • 🚀 Deep interest in aerospace/rocketry — turbojets, propulsion, and a from-scratch micro-drone build
  • 🔭 Long-term goal: a deep-tech career at the intersection of AI and aerospace

🛠️ Tech Stack

Python C++ TypeScript React Node.js PostgreSQL PyTorch Flutter Kotlin Assembly ESP32 Linux


🚀 Featured Projects

Brain-computer interface using EEGNet + PyTorch, achieving 88% cross-subject accuracy across all 9 subjects on the BNCI2014009 dataset. FastAPI backend + React frontend for real-time signal visualization.

🖥️ HelixaOS

A custom x86 operating system built from scratch — 2-stage bootloader, protected mode, GDT/IDT, VGA/VESA graphics — written in Assembly and C/C++ with a self-built cross-compiler toolchain.

Assembly C/C++ x86 OS Internals

Production ERP system built during my Fresco Global internship, handling 500+ daily orders across 4 parallel workflows, with an ML-based engine for employee-to-task assignment.

🤖 AgentOS

A modular Android AI agent — Flutter + Kotlin — with pluggable tools (calendar, SMS finance tracking, notifications, file handling), backed by a three-layer memory system and an LLM orchestration layer.

🔭 Currently Exploring

  • 🛰️ Designing a 1U CubeSat demonstrator with onboard AI triage for sensor/imagery prioritization
  • 🚁 Building an ESP32-S3 micro drone from scratch with custom PID firmware
  • 🐧 Running Alpine Linux in a chroot on a KaiOS feature phone (Spreadtrum SoC hacking)
  • 🔥 Studying turbojet propulsion and de Laval nozzle design for a DIY engine build
