BuildWithRani

Short Explanation

BuildWithRani is a documentation-first platform built to clearly communicate backend architectures and design decisions. It uses an MDX-driven content pipeline to present domain models, API contracts, lifecycle flows, and access control rules in a structured and maintainable format.

Project Goals

The goal of this project was to create a maintainable documentation system that accurately represents backend system design. The focus was on clearly communicating domain boundaries, request/response flows, and architectural decisions in a way that is easy to evolve alongside the codebase.

Tech Stack Used

• Next.js: Built a static and dynamic documentation platform with optimized routing and content rendering.
• MDX: Authored technical documentation using Markdown with embedded components for structured and reusable content.
• Tailwind CSS: Applied a clean, minimal design system to keep focus on technical content readability.

Features

• MDX-Driven Documentation Pipeline

  Implements an MDX-based content system that allows technical documentation to be authored, structured, and rendered with reusable components and consistent layouts.

• Backend Architecture & Domain Modeling Documentation

  Presents backend system design by documenting domain boundaries such as Product, Cart, and Order, along with their responsibilities and interactions.

• API Contracts & Request Flow Representation

  Documents REST API contracts, request/response structures, and authorization rules to provide a clear understanding of backend communication flows.

• Maintainable Content Structure

  Organizes documentation to scale with additional projects and systems without tightly coupling content to UI or routing logic.

The Problems and How I Deal With It

• Communicating backend system design clearly without relying solely on code or informal explanations.
• Keeping technical documentation maintainable as systems evolve over time.
• Representing domain boundaries and responsibilities in a way that is easy for readers to reason about.
• Documenting API contracts and access rules without duplicating or tightly coupling them to implementation code.
• Balancing technical depth with readability for developers reviewing the system.

Lessons Learned

• Separating content structure from presentation simplifies long-term maintenance and iteration.
• Readable representations of API contracts and request flows reduce the need to infer behavior from code alone.
• Designing a clear information hierarchy improves how quickly engineers can reason about a system.
