Developer ui ux designer

I am looking for someone who can: Design and develop the platform from the ground up, or help improve an existing prototype. Recommend the right technologies and architecture. Build a working minimum viable product (MVP). Help identify technical challenges and practical solutions. Test the platform and fix bugs. Advise on hosting, deployment, security, and maintenance. Communicate progress consistently. Collaborate on future improvements and product development. Think beyond writing code and contribute ideas that can make the product successful. Experience building startups, SaaS platforms, mobile apps, web applications, or online marketplaces would be an advantage.
