FAQ
What do I need to provide before we start?
Just your idea and any references you like. I'll help you define the requirements, features, and tech stack during our consultation. If you have wireframes, designs, or documentation—great! If not, I'll guide you through the planning phase to make sure we're aligned before we start building.
Do you provide post-delivery support?
Yes! Every package includes 30 days of bug fixes and minor adjustments after delivery. For ongoing maintenance, feature additions, or long-term support, we can discuss a monthly retainer or separate order.
Can you work with my existing codebase?
Absolutely. I can jump into your existing project to fix bugs, add features, optimize performance, or refactor code. Just share your repository (GitHub, GitLab, etc.) and I'll review it before we start to give you an accurate timeline and cost estimate.
What if I need changes after delivery?
Minor revisions and bug fixes are included in your package for 30 days after delivery. For major feature additions or scope changes, we can create a new milestone or separate order. I'm always available to discuss your evolving needs.
Can you integrate third-party services?
Yes! I have extensive experience integrating: - Payment gateways (Stripe, PayPal, Braintree) - AI APIs (OpenAI, ChatGPT, Claude) - Communication tools (Twilio, SendGrid, Mailchimp) - CRMs and databases (Supabase, Firebase, PostgreSQL) - Any custom API your business needs
