Tax Vision bridges that gap by letting users quickly convert between the two and better understand their take-home pay.</p> <p>For me, this project was about:</p> <ul> <li>Turning a real-life pain point into a usable tool</li> <li>Keeping the UI clean and focused on one core problem</li> <li>Experimenting with faster development workflows using AI tooling</li> </ul> <p>Repository:<br> 👉 <a href="https://github.com/kobenguyent/tax-vision" rel="noopener noreferrer">https://github.com/kobenguyent/tax-vision</a></p> <h2> Demo </h2> <p>You can explore the project here:</p> <ul> <li> <strong>Source code:</strong> <a href="https://github.com/kobenguyent/tax-vision" rel="noopener noreferrer">https://github.com/kobenguyent/tax-vision</a> </li> <li> <p><strong>App features:</strong></p> <ul> <li>Gross → Net salary calculation</li> <li>Net → Gross salary calculation</li> <li>Simple, user-friendly interface</li> <li>Clear breakdown of results</li> </ul> </li> </ul> <p>The repo includes screenshots and setup instructions so you can run the app locally and try different scenarios.</p> <h2> My Experience with GitHub Copilot CLI </h2> <p>Using <strong>GitHub Copilot CLI</strong> felt like having a very fast, very patient pair-programming partner in the terminal.</p> <p>I mainly used it to:</p> <ul> <li>Scaffold parts of the project structure quickly</li> <li>Generate boilerplate code and configs without breaking flow</li> <li>Get instant suggestions for commands, scripts, and fixes while staying in the CLI</li> </ul> <p>What stood out most was how much it <strong>reduced context switching</strong>. Instead of jumping between docs, Stack Overflow, and my editor, I could ask Copilot CLI directly what I needed and keep building momentum.</p> <p>It didn’t replace thinking or design decisions—but it <em>did</em> remove a lot of friction. That made the whole process more enjoyable and let me focus on what mattered: building something useful.</p> devchallenge githubchallenge cli githubcopilot
