Hi, This is Elias from Miami. I’ve reviewed your offer, and from what I understand, you’re looking for a hands-on Full-Stack Engineer who can take a product from concept to production—covering everything from architecture and cloud infrastructure to mobile/web frontends, backend services, DevOps, and AI/ML integration. The goal is to deliver a scalable, production-ready MVP in 6–8 weeks, then grow it to handle tens of thousands of users and investor-level technical scrutiny. With over 10 years of experience in full-stack engineering, I’ve led several 0→1 startup builds, owning the entire stack and making key architectural decisions to balance speed, scalability, and security. I focus on delivering real, usable products fast while leaving room for rapid iteration. I’d be excited to bring that same approach here and help turn your vision into a high-growth reality. A few specific questions: Q1: Do you have an initial tech stack preference, or should I recommend one optimized for rapid MVP delivery and scaling? Q2: For AI/ML features, are we starting with basic integrations (e.g., API-based) or building custom models early on? Q3: Will there be an existing design/brand team, or should I handle UI/UX direction for the MVP? Q4: Is the first 1,000-user target organic or supported by a pre-planned marketing push? Looking forward to connecting. Regards, Elias
