vayu
college-projectapril 2026
- production-grade air quality forecasting system for 29 indian cities — live aqi, 6h/12h/24h forecasts, and pollutant source attribution, all in one dashboard
- xgboost regressors trained on 846k hourly readings predict aqi at +6h, +12h, and +24h horizons. xgboost classifier maps current pollutant levels to cpcb's 6-category scale (good → severe)
- shap treeexplainer provides per-prediction feature attribution — shows exactly which pollutant drove each forecast. nmf decomposes the pollutant matrix into latent source profiles for city-level pollution source attribution
- live data pipeline runs hourly via github actions: hits waqi api (multi-station median to avoid single-sensor noise) + openweather air pollution api for raw pollutant concentrations. persists to supabase, serves via fastapi
- deployed and live — frontend at vayu.rachitgoyal.in, backend on render, models hosted on huggingface

hackathonmarch 2026 · india innovates 2026, bharat mandapam
- delhi's road intelligence & safety network - built for india innovates 2026, the world's largest civic tech hackathon, held at bharat mandapam, new delhi. never attending a government hackathon again.
- turns delhi's 3 lakh zomato/swiggy/zepto delivery riders into a passive pothole detection network - they just ride, the app maps every road hazard in real-time
- dual detection: on-device lstm neural network on the accelerometer classifies pothole severity (s1/s2/s3), while yolov8-nano on the forward camera catches water-filled potholes and road edge crumbling 4-5 seconds before impact
- confirmation engine: 3+ accelerometer reports at the same gps coordinate → confirmed on public map. yolo water detection at 91%+ confidence → immediate alert, no wait
- addresses 50 two-wheeler deaths and ₹3,450 crore in annual damage across delhi - connects mcd, ngos, delivery riders, and citizens in one coordination platform

only team to take on the ai video production pipeline challenge in the pharmaceutical space - focused on building for real industry expectations where accuracy and compliance are critical
atrio
personalmedical aijanuary 2026
- ai-assisted angiography workflow platform for cardiologists — turns raw DICOM cine images into prioritized findings, visual evidence, and structured reports
- yolov8-based stenosis detection model: detects and localizes coronary blockages with bounding boxes, identifies the affected artery and vessel segment, and estimates percentage luminal blockage per lesion
- findings inbox surfaces the most critical frames automatically — doctors jump straight to relevant detections instead of scrubbing through hundreds of frames manually
- human-in-the-loop design: ai never finalizes any finding without explicit doctor approval. accept, flag, or edit inline
- voice input during live procedure — doctor records observations while catheter is still in the body, converted to structured timestamped notes
- auto-generates one-page angiography report and procedure notes from voice + detection output
- originally built this for hackaxios but ended up submitting bloop instead — and won. atrio stayed in the drawer. might bring it back.

hackathonjanuary 2026
- ai-powered skin health platform connecting dermatology, mental health, and environmental factors
- built the first android app that combines skin condition detection using fine-tuned dinov2 vision transformers
- mood tracking with emotional pattern analysis and a voice-based mental health agent called "solace"
- my first android app-learned react native, mobile ml inference, and built a production-ready health product from scratch
- early detection can prevent up to 80% of flare-ups
trained custom ml models on diverse skin tones and lighting conditions, deployed inference on-device for real-time diagnosis

bloop
hackathonjanuary 2026
- ai stem learning platform that transforms structured prompts and uploaded documents into fully animated, narration-synchronized educational videos
- engineered end-to-end: llm plans the scene, manim handles programmatic animation, azure tts adds narration, sadtalker generates photorealistic talking avatars — all orchestrated through a fastapi backend
- scene-isolated fault-tolerant rendering: each manim scene runs in an independent context. failures trigger llm-based auto-repair (error log → corrected code → retry). unrecoverable scenes skipped gracefully — 92% render success, 85% auto-repair recovery
- won 2nd overall at hackaxios 2k25 (iiit bhopal × aws). originally built atrio for this hackathon, switched to bloop last minute — and it worked.

built this for rangrezz ntf, the largest theatre fest of india at chitkara uni. the official deployment link is currently paused because they won't buy us vercel premium, but the preview deployment is still live and fully functional
key lesson
use cdn for images instead of bloating the public folder-learned this the hard way when deployment kept timing out
