👋 Built an app with AI but struggling with bugs, broken features, or code that just won't work? I can help! I'm a Full-Stack Developer with 7+ years of software development experience, specializing in building, debugging, fixing, and improving web applications. AI coding tools like ChatGPT, Claude, Cursor, Lovable, and Bolt can speed up development significantly. But when errors pile up, APIs stop working, or the application isn't ready for production, you need someone who understands the code behind the scenes. That's where I come in. 🛠️ Whether you need to fix a vibe-coded application, complete an unfinished project, resolve difficult bugs, or build a new feature, I'll help you turn your ideas into reliable, working software. 🤖 AI-Generated Code & Vibe Coding Fixes Have an application that's almost working but keeps breaking? Let's get it sorted. ✅ Debug code generated by ChatGPT, Claude, Cursor, Lovable, Bolt, and similar AI tools. ✅ Fix runtime errors, TypeScript issues, and broken functionality. ✅ Resolve frontend, backend, API, and database integration problems. ✅ Fix authentication, form submissions, and data-handling issues. ✅ Clean up duplicated code and improve maintainability. ✅ Review code for common security, performance, and reliability problems. 💻 Full-Stack Web Development From frontend interfaces to backend logic, I can work across your application. ⚛️ Frontend: React, TypeScript, JavaScript, HTML, CSS ⚙️ Backend: Node.js, Express.js, REST APIs 🗄️ Databases: MySQL, Oracle, SQL, PL/SQL 🔗 Integrations: Third-party APIs, Airtable, Zapier, custom services 🛒 E-commerce: BigCommerce, Stencil CLI, storefront customization ☁️ Tools & Analytics: Git, GitHub, GA4, Looker Studio, Google Cloud Platform 🔧 What You Can Hire Me For 🚀 Fixing an AI-built MVP before launch 🐛 Troubleshooting bugs in an existing web application 🔌 Connecting APIs, databases, and external services 🧩 Building new features in an existing codebase ⚡ Improving SQL queries and database performance 🛠️ Refactoring messy code and fixing technical issues 📦 Completing unfinished projects and making them more reliable 🎯 My Approach I don't just patch an error and hope for the best. I work to understand the problem, identify its root cause, and implement a fix that fits your existing application. My process is simple: 1. 🔍 Investigate: Understand the codebase and reproduce the issue. 2. 🧠 Diagnose: Identify the root cause and explain the solution. 3. 🛠️ Fix: Implement the changes using the right tools and approach. 4. ✅ Test: Verify the fix and check for related issues. 5. 📝 Deliver: Summarize what changed and what you need to know. I use AI-assisted development tools where they make sense, while applying real software engineering experience to review the output and make sure the solution is appropriate for your project. 🤝 Let's Get Your Project Working!
