You will get a PDF generator that fills your template from your Excel or CSV data
Project details
Stop copy-pasting into the same document. Send your PDF template and a spreadsheet, and you get a generator that produces a finished, print-ready PDF for every row — invoices, certificates, letters, statements.
Your artwork is never redrawn. Values are placed onto a copy of your original file at fixed positions, so every document is pixel-identical to your design. Positions live in a simple settings file, not in code — when your template changes later, it’s a settings tweak, not a rewrite.
Before delivery, the full test batch is verified by reopening every generated file and checking what actually landed — not by trusting that the script ran.
The finished generator runs entirely on your computer — nothing is uploaded to any online service. The script runs on Windows, macOS and Linux with free Python; a point-and-click option is available as a simple local web page (Windows, Mac or Linux) or a macOS app.

About Naveen
AI/LLM Engineer | Java & Spring Boot | RAG, Extraction & Evals
Faridabad, India - 11:39 am local time
That combination is rarer than it should be. Most AI engineering is Python-only, so if your stack is Java and you want LLM features in it, the hiring pool is thin. I've spent 7+ years in Java/Spring Boot and now lead engineering teams building LLM extraction pipelines in production.
In my day job, I'm an Associate Engineering Manager, running teams that turn unstructured documents into structured, reliable data. Accuracy is measured against human-verified baselines and held to contractual targets, with eval-gated deployment and golden-set regression testing before anything ships.
That evaluation discipline is what most LLM projects are missing. Wiring up an API call is easy. Knowing whether the output is actually correct — and catching it when a prompt change quietly breaks something that worked last week — is what separates a demo from something you can put in front of customers.
What I can help with:
• Java/Spring Boot backend and API development — my core expertise, 7+ years, microservices architecture with JUnit test coverage
• LLM extraction pipelines — pulling structured data out of PDFs, emails, forms and other unstructured documents
• RAG systems — retrieval quality, chunking strategy, embeddings, and keeping answers grounded in source material
• LLM stack — Gemini, OpenAI and Anthropic APIs; LangChain and LangGraph; pgvector for retrieval
• Evaluation harnesses — golden sets, regression suites, accuracy measurement, and eval-gated deployment, so you know when a change makes things worse
• Cloud and infrastructure — GCP and AWS, containerised with Docker and Kubernetes
• Identity and access management integration (Keycloak, Auth0)
• Python for data and pipeline work — pandas, ETL, Postgres, MySQL, MongoDB, Excel automation
Background: currently Associate Engineering Manager at Concirrus, building AI-powered underwriting automation for speciality insurance. Previously Senior Software Engineer at CoreValue Technologies. B.Tech in Computer Science.
I'm newer to Upwork than I am to engineering, so my rate is lower than it would be otherwise. You get honest estimates, clear communication, and a straight answer when something isn't the right fit for me.
If you have a specific problem in mind, send me the details, and I'll tell you honestly whether I'm the right person and what it would realistically take.
