Ultimate Remote Bookkeeper Toolkits | Freelance Contract
Fiverr • Freelance
Jun 2026 - Present • 1 mo
Converted an AI-generated prototype into a production-ready bookkeeping toolkit web application for a coaching business serving remote bookkeepers and accountants. The client had developed the initial concept with Claude AI but needed technical support to restructure the codebase, resolve deployment issues, and turn the prototype into a reliable live platform. I downloaded the original script, rebuilt the development workflow in VS Code, organized the React and Vite application, created a structured GitHub repository, and deployed the finished web app on Vercel. I also implemented a secure Claude API integration through Vercel Serverless Functions, protecting the Anthropic API key while enabling the platform’s ProAdvisor chat assistant to provide AI-powered bookkeeping and QuickBooks support. The completed platform now provides users with 40+ tools for bookkeeping training, accounting workflows, job applications, interview preparation, client onboarding, monthly tasks, year-end processes, and AI-assisted guidance. I also trained the client on how to manage the deployed system confidently. Key contributions: • Converted an incomplete AI-generated prototype into a production-ready web application • Restructured the React and Vite codebase for cleaner development and maintenance • Implemented secure Claude API and Anthropic API integration • Configured Vercel Serverless Functions to protect API credentials • Resolved deployment, proxy-routing, and API-response issues • Created and organized the GitHub repository with deployment documentation • Deployed the live application successfully on Vercel • Trained the client on platform management and ongoing maintenance Core technologies and services: React, Vite, JavaScript, Claude API, Anthropic API, Vercel, Vercel Serverless Functions, GitHub, VS Code, API Integration, AI Web App Development, Full-Stack Development, Deployment Troubleshooting, Git Version Control

Cornerstone PLC internal SaaS Form Builder With next.js, Claude Code, Supabase, Vercel
May 2026 - Present • 2 mos
Built a custom internal form builder for Cornerstone PLC designed to help teams create, manage, preview, and organize forms inside a clean, structured SaaS interface. The project was focused on improving internal workflow efficiency, simplifying form creation, and delivering a reliable tool that feels fast, intuitive, and easy for business teams to use. The application was developed using Next.js, Claude Code, VS Code, Supabase, GitHub, and deployed on Vercel. My role covered full-stack development, SaaS development, internal tool development, form builder development, API integration, workflow logic, and responsive UI implementation. I also handled the structure of the builder experience, including the field library, editing canvas, live preview panel, properties section, and input components such as text, text area, email, number, dropdown, radio, checkbox, and date fields. This project reflects my ability to turn a business requirement into a working product with clean architecture, strong user experience, and production-ready deployment. It also demonstrates practical experience with AI SaaS development, frontend development, backend integration, Supabase workflows, Vercel deployment, and GitHub-based version control.
Freelance Full-Stack Web Developer | Bubble.io to Next.js Migration | Claude Code
Dec 2025 - Present • 7 mos
Worked on LiveWall, an event-based photo and message sharing MVP that allowed guests and photographers to upload images, send messages, and have submissions reviewed by an admin before being displayed live. The product was initially built on Bubble.io, but after assessing the client’s need for full code ownership, better scalability, and more flexible billing, I recommended and led a complete rebuild using Next.js with an AI-assisted development workflow powered by Claude Code. I focused on recreating the core functionality in a more maintainable, code-first structure while preserving the original user experience and interface flow. The project involved building and organizing reusable components, managing source control with GitHub, developing in VS Code, and deploying the final version on Vercel for a reliable production launch. The result was a cleaner, faster, and more scalable SaaS MVP that gave the client full control over the product going forward.

This is my third time working with Emman, and honestly, he has been such a blessing. Every Claude web app idea I had was brought to life exactly the way I envisioned it, and he made the whole process feel easy and stress free. What I appreciate most is that he never assumes. He always asks questions...
