I need a dependable partner to turn my app idea into a polished, production-ready product while also setting up a straightforward contact form on our corporate site. For the app itself, I already have the core concept and basic user flows drafted; I now want you to handle everything from architecture and UI to final store submission, ensuring clean, well-documented code (Swift/Kotlin or cross-platform React Native/Flutter—whichever you feel best suits long-term maintainability). On the web side, the requirement is simple yet essential: a secure, spam-protected contact form that feeds directly into our CRM and triggers an email notification. It has to match the existing corporate design and be GDPR-compliant. Deliverables • A fully functional, tested mobile app (iOS & Android) ready for store release • Source code with clear documentation and build instructions • Implemented contact form on the company website, integrated with CRM and email alerts • Short hand-off session/walk-through so my internal team can take it from there Please outline your proposed tech stack, estimated timeline, and any similar projects you’ve shipped so I can see how your approach aligns with our quality and reliability standards.
