Halo CME Detection & Space Weather Prediction System
Title: ML-Based Early Warning System for Solar Storms (Smart India Hackathon Winner)
Problem: Geomagnetic storms and Coronal Mass Ejections (CMEs) threaten satellite infrastructure, but predicting their arrival and severity is a hard time-series forecasting problem with multi-scale temporal patterns.
My approach: I developed supervised time-series forecasting models (LSTM, GRU) trained on space-weather data, applying lag and rolling-window feature engineering to capture temporal dynamics across multiple scales. I also built a real-time ML-based alerting pipeline for risk assessment and forecasted key geomagnetic indices (Kp, Ap, Dst, Sunspot Number) 7 days ahead.
Tools used: Python, PyTorch/TensorFlow, LSTM, GRU, time-series feature engineering, MLflow
Result: Achieved a 7% improvement in CME/storm prediction accuracy and a 6% improvement in arrival-time prediction. Won Smart India Hackathon 2025 (Ministry of Education's Innovation Cell, Government of India), and the work was published as corresponding author in the Journal of Science, Computing and Engineering Research (JSCER), 2026.

Nayak (/naa-yek/)
n. Hindi for hero
Someone with unique strengths, hidden potential, and a story worth telling.
The idea is simple: everyone carries a superpower inside them. Something they're naturally great at but rarely stop to notice. Nayak helps you discover that hidden power, give it a name and a face, and share it with a community of people doing the same.
- Starting from the AI base
Nayak began with a single prompt. I used Bubble's own prompting guide to write a tight, well-structured first prompt. Clear about the app's purpose, the screens it needed, the data behind them, and the visual direction I was going for. It paid off immediately: the Bubble AI builder generated a solid, properly wired UI foundation on the very first try! Navigation and core pages already in place, not a loose skeleton I'd have to rebuild from scratch.
From there I leaned on Bubble's AI agent to move fast. Spinning up the additional screens and UI states I needed, refining layouts, and wiring flows without hand-building every element. It turned the usually-slow part of a build into something I could iterate on in minutes.
- What Nayak does
A short, deliberate 5-question quiz reveals your hidden superpower.
The Anthropic Claude API interprets your answers and generates a personalized power! Its name, its description, and its personality.
The Pollinations API generates a one-of-a-kind character illustration for it, so every result is a unique, custom hero card for you! No two alike.
Your power then joins the community wall, where you can explore everyone else's superpowers and like the ones that resonate with you.
- Category: Social / Community
Nayak is built around shared discovery, not solo results. The quiz is only the entry point. The heart of the app is the community wall, where every user's superpower lives alongside everyone else's. You can browse the powers other people have discovered, see what makes each one unique, and like the ones that resonate with you. It turns a personal moment of self-discovery into something collective: a growing, feel-good feed of people celebrating what makes each other special.
It's playful, personal, and a little addictive!
Part personality quiz, part social feed, all built around one feel-good idea: there's something special in you. So explore Nayak today and find your superpower!🤫
An unfinished AI MVP, a tight deadline and a pilot with 350 educator -definitely one of the more memorable projects we've worked on.
What's usually the hardest part of getting an MVP ready for real users?
Love seeing AI solving real problems
