Case Study: Build That Thing - A Suite of Free, Privacy-Focused Tools

A deep dive into 'Build That Thing,' a collection of powerful, client-side tools designed to be free, private, and easy to use without any sign-ups.
The Challenge: The Need for Simple, Private, and Free Online Tools
Many online productivity tools come with a catch: they require user sign-ups, are cluttered with advertisements, or raise concerns about data privacy. The challenge was to create a suite of essential, high-quality tools that were completely free, respected user privacy by running entirely on the client-side, and were accessible to everyone without the friction of creating an account.
My Solution: A Collection of Powerful, Browser-Based Utilities
I developed "Build That Thing," a project dedicated to providing a suite of powerful tools that run directly in the user's browser. This approach ensures complete privacy, as no data ever leaves the user's computer. The platform is designed with a clean, intuitive interface, making each tool a pleasure to use.
- Invoice Builder: A simple yet powerful tool for freelancers and small businesses to create professional invoices with a live preview and instant PDF download.
- Resume Builder: Helps users craft a professional resume with a clean template, offering a live preview and PDF export to streamline the job application process.
- Image Converter: A versatile tool for converting images between different formats (e.g., JPG, PNG, WebP) directly in the browser, perfect for web developers and designers.
- Linkpage Builder: An easy way for users to create a simple, elegant "link-in-bio" page to consolidate all their important links in one place. This is a great example of the custom web design solutions I provide.
Technologies Used
The project was built using a modern, efficient tech stack to ensure a fast and responsive user experience:
- Framework: Vite and React with TypeScript for a fast development environment and a robust, type-safe codebase.
- Styling: Tailwind CSS for creating a clean and consistent user interface across all the tools.
- Client-Side Logic: All tools are built with pure JavaScript/TypeScript, ensuring that all data processing happens locally in the user's browser.
- Deployment: Hosted on Vercel for fast, global delivery.
This project demonstrates my capability to build practical, client-side applications. If you have an idea for a custom tool or a full-stack web application, I'd love to hear about it. Let's build that thing together!
