About
01Systems first.Markets on the side.
I'm an Integrated M.Tech Computer Science student at JIIT with a bias for systems that hold up under load — FastAPI services, Elixir backends, and AI pipelines you can actually observe.
Outside of shipping, I trade futures and options and follow macro markets. I like connecting those instincts to engineering: latency, risk, and clean abstractions.
Hit me up if you're building something in AI infra, backend systems, or open source — or if you just want to talk markets.

Work
03Selected projects
A few builds that show how I think about interfaces, signals, and systems that people actually use.
- Real-time signal processing pipeline from Emotiv Epoc X headset input.
- Mapped neural signals into game controls without physical input devices.
- Interactive GUI and game loops built with Pygame.
- Structured around OOP for maintainability and extensibility.
- OpenCV + NumPy pipeline for image processing; Pandas for analysis.
- Streamlit and Pygame surfaces for interaction and demos.
