How I Built a Live Web Editor for RenderCV Using Gemini
Resumes as Code: The Elegance of RenderCV
If you are an engineer or an academic, writing resumes in MS Word is a formatting nightmare, and custom LaTeX templates are often too verbose to maintain.
Recently, I stumbled upon a brilliant Python project called RenderCV. It allows you to write your resume content in a clean, structured YAML file and generates a beautifully formatted PDF with perfect typography using Typst under the hood. It treats your resume like code, which means you can version-control it, focus strictly on the content, and let the tool handle page margins, alignment, and styling.
However, RenderCV was designed primarily as a command-line interface (CLI) tool. Every time you make a change, you have to run rendercv render John_Doe_CV.yaml, check the output, open the PDF viewer, and check the alignment. If you make a validation or schema error, you have to read CLI compiler tracebacks.
I wanted to bridge this gap by adding a Live Web Editor—a local single-page web app with a side-by-side Monaco editor, live PDF preview, instant schema validation, and interactive theme/section toggles.
With the help of Gemini, I successfully built and integrated this web interface directly into RenderCV! Here is how we did it.
How I Built PDF Ink for Comfortable Online Learning from PDF Books
Why read PDFs if you can’t write on them?
Hello everyone! I’m Albert, and I love making tools more convenient.
If you have ever tried self-learning, studying programming textbooks, or reading complex technical documents from PDFs on your laptop or tablet, you know this struggle. You open a book, want to highlight a key code snippet, draw a quick diagram arrow next to an explanation, or leave a note on the margins — and realize that standard PDF viewers are either bloated, commercial, or they completely lose your drawings if you accidentally refresh the tab.
I wanted to fix this and create PDF Ink — a lightweight, fast web application for reading and interactively annotating PDF books directly in the browser.
