About

Professional summary

I am a Computer Science and Engineering undergraduate and AI engineer focused on building retrieval-augmented generation (RAG) and document AI systems. I work primarily with Python, FastAPI, large language models, retrieval pipelines, and backend services.

I have built RAG applications using hybrid search, reranking, citations, OCR, and evaluation workflows. My work includes improving retrieval quality and latency through dense retrieval, BM25, pgvector HNSW, and cross-encoder reranking.

I have experience developing reliable AI infrastructure, including an OpenAI-compatible LLM gateway with rate limits, retries, provider failover, circuit breakers, streaming, tracing, and operational dashboards. I use Redis, PostgreSQL, OpenTelemetry, Prometheus, Grafana, and Docker in these systems.

During my AI Engineering internship, I built a Siemens Opcenter RAG assistant for manufacturing documents. I also developed document ingestion pipelines using PDF parsing and OCR tools and measured system performance through local benchmarks.

I enjoy solving algorithmic problems and have solved more than 1,000 problems across LeetCode and GeeksforGeeks. I have also mentored students in C programming and contributed to undergraduate research on influence maximization in social networks.

I am seeking opportunities where I can contribute to applied AI, LLM engineering, RAG systems, backend development, and document intelligence products.

Career history

AI Engineering Intern Keystone Automation Solutions Private Limited

Built a Siemens Opcenter RAG assistant using FastAPI, Streamlit, and LangGraph for manufacturing-document workflows. Improved Recall@5 from 48.9% to 73.9% against dense-only Chroma retrieval on 44 labeled questions, with page-level citations.

Implemented PDF and OCR ingestion with PyMuPDF, Tesseract, and PP-StructureV3. Measured median Tesseract extraction time at 0.58 seconds per page across 16 rasterized pages from eight manuals.

Configured two FastAPI replicas with PostgreSQL-backed memory, Redis caching, rate limiting, request-state management, citation validation, LLM-as-a-judge evaluation, and LangSmith tracing.
