SHISTECHDelhi, India
  • Co-founded and scaled a technical organization to 50+ members, building all internal software tools, automation systems, and data pipelines from scratch to support a 6,000+ participant annual event
  • Designed and shipped a full-stack cryptic hunt platform using Node.js, EJS, and vanilla JavaScript, sustaining 100+ concurrent users across a live competitive event with zero downtime
  • Drove end-to-end technical ownership across software, data, and operations infrastructure for four years - building, iterating, and maintaining systems with real users and real stakes
Projects
The Originality Engine | Python, NLP, Transformers, FAISS, Pandas, NumPyFeb 2025
  • Built a research-grade ETL and ML pipeline to ingest, embed, and score arXiv abstracts using transformer sentence models and FAISS nearest-neighbour indexing
  • Designed a modular, script-driven architecture with clearly separated ingestion, transformation, indexing, and scoring stages; evaluated outputs against ground-truth similarity metrics
Grounded | JavaScript, Gemini 2.5 Flash, ElevenLabs, face-api.js, Web Audio APIMar 2026
  • Shipped a real-time multi-service AI pipeline at Hack Canada 2026: webcam input, ML-based stress detection, LLM response generation, and TTS voice output, orchestrated end-to-end in under 24 hours
  • Engineered async coordination across three external APIs (Gemini, ElevenLabs, face-api.js) with concurrency guards, fallback logic, and graceful error recovery that held up reliably through a live demo
Disease Detection | Python, TensorFlow, Flask, Pandas, scikit-learn, Raspberry PiAug 2023
  • Trained a dual-mode TensorFlow diagnostic model applying image preprocessing, normalization, augmentation, and iterative hyperparameter tuning to improve generalization across test sets
  • Deployed the model end-to-end on Raspberry Pi via a Flask API, implementing confidence thresholding, structured JSON responses, and full inference pipeline management for real-time portable use
Achievements
National Winner - IIT Delhi Youth Ideathon2024
  • Placed first nationally at the Indian Institute of Technology Delhi's Youth Ideathon, competing against university teams across India in a technology and innovation challenge.
