FAQ
Do I need to provide the technical documentation or database structure for my system?
No, you do not need any technical background. As a full-stack engineer, I handle everything from scratch. You only need to explain your daily business workflow, what your staff does manually, and your ultimate goals.
Do I need to provide my source code before you start?
Yes, please share your source code or provide access to your repository before I begin. This allows me to analyze the issue accurately and give you a realistic timeline and price.
Will you sign a Non-Disclosure Agreement (NDA) to protect my business data and source code?
Absolutely. I understand that your proprietary business data, client details and custom software code are your company's most valuable assets. I am completely open to reviewing and signing a standard mutual NDA before you share any system files or access credentials.
