Restore Wellness: In-Home Massage Marketplace
A three-sided in-home massage marketplace shipped to the App Store. Clients book a licensed therapist to their home, the therapist accepts and fulfills the session, and an admin dispatch panel runs bookings, compliance, and payouts. Stripe Connect handles the client payments and therapist payouts.
TalkToData: Natural Language SQL
AI-powered SQL query interface that converts plain English to SQL. Supports PostgreSQL, MySQL, SQLite, SQL Server, and MongoDB with AI-driven query explanations and error fixing.
ESG Report Search: Cited Answers from Sustainability Reports
A personal project that rebuilds my USC Marshall research pipeline: ask S&P 1500 sustainability reports a question and get an answer citing the exact page each fact came from. Hybrid keyword and vector search with a reranker runs over 289 reports (27,928 passages), and a checker removes any citation the model makes up before the answer is shown. Retrieval is measured against 50 hand-labelled questions.
ReachOut (warmreach): AI Job Outreach
After you apply for a job, finds the founder, the engineering lead and the recruiter at the company, has Claude write each of them an email grounded in real company facts, tailors your résumé to the job, and lands everything as Gmail drafts. Follows up until someone replies and never emails the same person twice.
Music: Personal Music Library
My own music app at music.rutwik.dev. Curated Hindi, Gujarati and Indian hip-hop collections that rotate with the hour in India, a queue you can reorder, and playlists built a song at a time or saved from YouTube. It hosts no audio: every song plays through YouTube, so each play counts for the artist. Read-only for visitors.

Research Assistant
USC Marshall, Los Angeles, CA
- Built a RAG-based semantic search and chat platform in Python and LangChain over 10K+ OpenAI embeddings stored in Chroma, letting researchers query 500GB+ of structured and unstructured sustainability disclosures in natural language.
- Developed chunking and schema-guided LLM pipelines that extract structured ESG fields from unstructured disclosures.
- Shipped a React dashboard and chat interface for 30+ researchers, cutting 15+ hours per week of manual review.
- Integrated an LLM layer grounding answers in retrieved disclosures with citations to reduce hallucination, plus a feedback loop capturing researcher ratings to refine retrieval accuracy over time.
