Building a scalable autonomous-driving stack adapted to unstructured, laneless Indian traffic, working inside an Agile pod alongside senior engineers.

• BEV Perception & Object Detection: Developing bird's-eye-view perception and detection modules for a self-driving stack tuned to chaotic, laneless Indian roads. Validated end-to-end in CARLA simulation.
• Dino: An offline in-vehicle voice assistant: openWakeWord detection → faster-whisper ASR → Gemma intent classification → Piper TTS, running entirely on-device via llama.cpp on an NVIDIA Jetson Orin Nano Super. Zero cloud dependency.
• NOVA: The successor in-cabin assistant, extending the stack to handle in-car support queries.

Shipped UniBot, a production RAG assistant for a high-velocity fintech application, from retrieval pipeline to production scale.

• UniBot: A production RAG assistant. Built the LangChain + Hugging Face retrieval pipeline, the PostgreSQL data layer, and the Node.js interface, improving response reliability and scaling the system to production.

SCAATA: Self-Critiquing Autonomous Algorithmic Trading Agent

An end-to-end reinforcement-learning trading pipeline across 6 equities. LLMs scraped and normalised 79 algorithmic strategies into a 245,000-sample expert dataset, then a RecurrentPPO agent was warm-started via imitation learning.

Nomly: Full-Stack Airbnb Clone

A production-style booking platform built solo for a full-stack take-home assignment: real JWT auth with bcrypt-hashed passwords, a booking-overlap algorithm that guarantees zero double-bookings, and a full host CRUD dashboard alongside the guest-facing browse, search and book flow.

Redactly: PII Redaction Tool

A CLI and web tool that finds personally identifiable information in PDFs and text, then writes a redacted document with every PII value swapped for a consistent, realistic fake. Uses a hybrid regex + spaCy NER pipeline, evaluated end-to-end against a real SEBI IPO prospectus rather than synthetic data.

Fake News Detection: NLP Misinformation Classifier

An NLP pipeline that classifies news articles as real or fake, comparing Logistic Regression, SVM, Naive Bayes and Random Forest across accuracy, precision and recall to pick the strongest model.
