Senior Analyst, Product Documentation Development 
 
 
 
 
(Mar 2023 - ongoing) 
Senior Technical Writer | AI Automation Specialist and Tool Developer 
Apart from regular tech-writer related responsibilities, I have been working to future-proof the team and processes as the 
world is adapting to AI. Below are some of the things that I have built: 
 
AI-Chat bot for technical documentation 
Built a RAG-based solution and leverage Vector DB, Graph DB, chunking, ranking, indexing, semantic search, etc. 
This is an independent, offline AI agent that can ingest PDFs and HTML files and then provide answers related to 
them. Since knowledge is not internalized, and the SLM acts only on the retrieved chunks, there is near zero 
hallucination.  
 
PDF-Checker: Automates the process of checking various errors in PDFs and HTMLs before they are published on 
the server. This tool detects errors, such as broken links, various formatting errors, missing images, incorrect legal 
information, incorrect author, document title, filename, etc. This collectively saves 3-5 days for the entire team of 
20 writers. 
 
CRN-Maker: Automates the process of creating Customer Release Notes. It pulls data from the JIRA tickets and 
confluence pages and processes them to create release notes. It takes care of the formatting errors, and dita tags, 
and creates FrameMaker ready ditamaps and topics files, that can be directly uploaded to the CMS. It can also 
compare older and newer versions of CRN to tell the delta and identify the changes. It saves 3-4 days of work for a 
writer for each CRN. 

 
Many other case-specific small scripts: Such as, a script to zip and upload entire documentation suite (50+ folders, 
each having 10 pdfs and htmls folders) to production server, a script to automate process of indexing and creating 
a detailed TOC for semiconductor and chips documentation (excel to pdf), tools to extract images and tables from 
legacy documentation, etc.

Personal Projects and Highlights

• Personal Projects and Highlights
• Meta-CRAG-MM Challenge (2025): Designed and built a multi-source augmentation pipeline for multimodal (image +
• text) retrieval. Implemented custom sentence-level embeddings and hybrid scoring mechanisms combining cosine
• similarity, metadata matching, dialogue context, and diversity penalties. Developed a compact retrieval-augmented
• generation (RAG) system optimized for lightweight local models (e.g., Phi-2, Gemma-2B), balancing retrieval accuracy
• and model inference costs. Achieved high precision in multi-modal QA tasks without relying on large-scale LLMs.
• Image-Based Technical Search (2024): Built RAG-style tool that maps image inputs to index via OCR and caption
• embeddings.
• Research Papers and Extra Curricular
• Bumper Crash Analysis using Ansys (Oct 2015)
