Hi, This is not an AI generated proposal and I’d like the chance to discuss this project further with you. I understand you need someone who can stay involved as the product grows, not just complete separate tasks. The main challenge is keeping the application easy to improve while adding features and making good technical choices. I work as a solo full-stack developer and have experience building web applications with frontend and backend systems, APIs, databases, and deployment setups. This fits your need for someone who can handle different parts of the product and work independently. My approach would be to understand the current application first, improve the code structure, add features carefully, and keep future changes easier to manage. The exact effort depends on the complexity of the project, and I can give a better estimate once we connect. I have worked on similar web products and can share relevant past work once we align. If you have any questions then feel free to contact me. I am available to start immediately and my time zone is GMT+5. Are you starting with an existing codebase? Regards, Ahmed

I usually work with modern stacks like React for frontend and Node.js for backend, along with REST or GraphQL APIs, and I’m comfortable working with deployments using platforms like AWS or Vercel depending on what the project needs.
