DHRUV MAHESHWARI

A minimal RAG app where you upload a PDF, let the backend ingest it as chunks and embeddings with ChromaDB, then ask questions through direct retrieval or translation modes like multi-query, RAG fusion, decomposition, step-back prompting, and HyDE. Every answer shows the exact chunks retrieved plus latency and token logs, so the grounding is fully auditable.

Move playlists between Spotify and YouTube Music, then share them straight to a friend on the same network using encrypted peer-to-peer transfer. Matching is done with fuzzy title/artist scoring and a custom reliable-UDP protocol.

FastAPI app for Hindi, Tamil, and English service requests. It can transcribe audio or analyze text, then returns structured JSON with detected language, translation, intent, confidence, and urgency.

Built a full-stack social media platform with Django and MySQL supporting authentication, posts, comments, likes, and a symmetric friendship model. Enforced data integrity with check and unique constraints, Django-level permission checks, and database-side logic for mutual-friends lookup, friend counts, and personalized feeds.

Interactive Three.js digital twin of the PES University EC Engineering Block with first-person traversal, interior exploration, teleport hotspots, and guided navigation flow. Baked an animated simulation of students scattered across the campus building using Blender and Python.

Interactive WebGL-based 3D simulation of a 2000cc car engine modelling the impact of varying oil levels on temperature, performance, and mechanical behavior. Real-time physics-driven visualization covering thermal dynamics, oil degradation modelling, RPM-driven piston/crankshaft kinematics, and dynamic thermal overlays highlighting heat and stress zones.
