Hi, I'm Palak Bhati

AI Engineer & Python Developer | GenAI, RAG, Agents · Django, FastAPI, PostgreSQL | Open-source contributor (Sugar Labs, Kubeflow) | Indore, India

I build two kinds of things in Python: LLM applications that are meant to run in production (access-controlled retrieval, guardrails, evaluation in CI, cost tracking), and backend web apps with role-based access, PostgreSQL, Pytest suites and Docker deploys on Google Cloud Run.

Portfolio | LinkedIn | Email

Open to: AI Engineer, GenAI Engineer, Python Developer and Backend Developer internship roles. Available now.

AI & LLM projects

Project What it shows Live
secure-rag-rbac-chatbot RAG with role-based access enforced inside the vector store (Qdrant payload filters), two-layer prompt-injection guardrails, PII redaction, Ragas evaluation that blocks PRs in CI, LangSmith tracing, per-request cost tracking Demo
nlp-log-classification Hybrid classifier that routes each log to regex, MiniLM embeddings + Logistic Regression (99% accuracy on held-out data), or an LLM fallback; DBSCAN clustering to find regex patterns; FastAPI on Cloud Run API docs

Python backend projects

Project What it shows Live
job-portal Django job board with employer and job-seeker roles, paginated search, permission-checked resume downloads, 74 Pytest tests; Docker on Cloud Run with PostgreSQL, Cloud Storage and Secret Manager Demo
ecommerce-django-react Django REST Framework API + React store: JWT auth with automatic token refresh, per-user cart and order endpoints, checkout in one database transaction Demo
