FAQ
Question 1: What is "Vibe Coding" and how does it benefit my project?
Answer: Vibe Coding is an AI-augmented development workflow. I use advanced AI tools (like Cursor and Copilot) to generate boilerplate and debug code rapidly. For you, this means faster delivery times and lower costs without sacrificing the quality of the final Java application.
Question 2: Do you provide support for existing Java projects?
Answer: Yes! Whether it's an old Java 8 monolith or a modern Spring Boot Microservice, I can jump in to fix bugs, add new features, or optimize your MySQL database performance.
Question 3: Can you integrate AI models into my Spring Boot app?
Answer: Absolutely. I can integrate LLMs (like GPT-4 or Gemini) into your backend to create chatbots, automated data processing, or AI-driven analytics features.
Question 4: Do I need to provide the source code?
Answer: Yes, for bug fixing and feature updates, I will need access to your repository (GitHub/GitLab) or the source code files. All your data and code will be handled with 100% confidentiality.
